The invention discloses a grinding process of the inner wall of an oil-free vacuum pump cylinder. Rough machining is performed on the inner wall of the cylinder, and the grinding tool for the oil-free vacuum pump cylinder is used for finishing the inner wall of the cylinder. The grinding process of the inner wall of the oil-free vacuum pump cylinder mainly includes the following steps: S1, rough grinding and installation of the cylinder body; S2, rough grinding and clamping of the cylinder body; S3, rough grinding and taking out the inner wall of the cylinder body; S4, fine honing of the cylinder body Installation; S5, the cylinder block is honed and taken out. In the invention, the processing technology of rough grinding and fine honing of the inner wall is adopted, and two different clamping structures are proposed to fix and clamp the irregular hole-shaped workpiece on the outer wall, so as to prevent the vacuum pump body from swinging in the process of processing, and increase the number of vacuum pump The fixing effect of the cylinder body improves the processing accuracy of the product, improves the sealing of the finished product, and ensures the quality of the product.

The invention discloses an anti-disengaging clamp which comprises two clamping units, wherein the two clamping units are matched and are of the same structure. The clamping units comprise clamping portions and reinforcing portions which are hinged to each other, wherein the clamping portions are hinged to achieve primary clamping of an object to be clamped. The length of the reinforcing portions is larger than that of the clamping portions, and one ends of the two reinforcing portions are respectively hinged to the tail ends of the two clamping portions. The two reinforcing portions can rotatetowards the front ends of the two clamping portions respectively so as to realize secondary clamping of the object to be clamped. Elastic limiting pieces are arranged in the reinforcing portions. Theelastic limiting pieces comprise springs and limiting pieces which are fixedly connected, the other ends of the springs are fixed in the reinforcing portions, and limiting portions are arranged at the tail end of the clamping portions. When the springs are compressed, the limiting portions and the reinforcing portions can rotate at one ends of the clamping portions. The anti-disengaging clamp hasthe advantages that the labor is saved, the clamping strength can be guaranteed in real time, the clamping is firm, and the placing size is small.

The invention discloses a waste tire hole detecting and filling device for waste tire reutilization. The waste tire hole detecting and filling device comprises a fixed shell and a conveying channel for conveying out a detected and filled waste tire. A first control block and a second control block for controlling the ground waste tire to rotate are arranged in the fixed shell, a first driving block and a second driving block for driving the first control block and the second control block, and a tire repairing device for detecting and filling the ground waste tire are arranged in the fixed shell. By means of the structural arrangement, the ground waste tire can be clamped through the first control block and the second block, separation of the waste tire is avoided, and the stability of tire repairing is guaranteed. By arranging the first driving block and the second driving block, the waste tire can rotate through the first driving block and the second driving block, so that the wholewaste tire is automatically repaired through the tire repairing device, and the repairing efficiency for the waste tire is effectively improved.

The invention discloses a gear shaft structure, and relates to the technical field of gear shafts. The technical problem that the axial direction of a gear cannot be fixed is solved. According to thetechnical key points, the gear shaft structure comprises a metal round rod shaft and a gear with which the metal round rod shaft is sleeved, the metal round rod shaft is internally provided with an inner cavity arranged on the coaxial line of the metal round rod shaft, the metal round rod shaft is provided with a notch through which the outer wall and the inner cavity of the metal round rod shaftcommunicate, a clamping groove is formed in the inner wall of the gear, a clamping block with the outer wall attached to the inner wall of the notch is arranged in the gap, one end of the clamping block extends out of the metal round rod shaft and is clamped in the clamping groove, and an abutting rod with the outer wall abutting against the surface, close to the axis of the inner cavity, of the clamping block is inserted into the inner cavity. The gear shaft structure has the advantage that the axial direction of the gear can be fixed.

The invention provides a multi-functional transfer device for an internally threaded copper pipe, comprising a transfer vehicle 1, a transfer vehicle 2 and a transfer vehicle 3 arranged in sequence from left to right, and the transfer vehicle 1 is connected with the transfer vehicle 2 through a first pull rope , the transfer vehicle 2 is connected with the transfer vehicle 3 through the second pull rope, and the structure of the transfer vehicle 1 and the transfer vehicle 3 is the same; and supporting system 2, the structures of supporting system 1 and supporting system 2 are consistent; the supporting system 1 and supporting system 2 are provided with internal thread copper pipes. The multifunctional transfer device for the internally threaded copper pipe provided by the invention can facilitate the transfer and storage of the large-sized internally threaded copper pipe in production workshops, warehouses and transportation, and at the same time help the internal threaded copper pipe to be rolled into a large coil. The technical effect has the characteristics of multi-function and excellent economic benefits.

The invention relates to the technical field of automobile spare parts and discloses a filament bending device for an automobile. The bending device comprises a first cylinder body. A first limiting groove is arranged in the inner surface of the first cylinder body. The first cylinder body is in sliding connection with a second cylinder body. A second limiting groove is arranged in the outer surface of the second cylinder body. The second limiting groove and the first limiting groove are oppositely arranged. Up-down symmetrical clamping plates are arranged in the second cylinder body. The clamping plates are arranged to be close to the inner wall of the second cylinder body. Space where filaments are arranged is formed between the clamping plates. Elastic pieces are connected between the clamping plates and the inner wall of the second cylinder body. Through holes are arranged in the second cylinder body and are in sliding connection with pushing rods. The pushing rods are abutted against the clamping plates. By inserting the filament into the second cylinder body, under the squeezing function of the first cylinder body, the filament is fixed and bent. The bending device is advantaged by good filament bending effects and high bending precision.
