Problems solved by technology

The most important process before the blade is formed is tooth making, and how to process the front and back of the thin steel plate with a thickness of only 7mm is less than 1.5mm in thickness, which seriously restricts the production efficiency of the blade
The defects of this fixture are: because the hydraulic oil can be compressed, there may be continuous vibration after the oil cylinder is stressed, which affects the cutting speed of the machine tool, thereby affecting the processing efficiency

Embodiment 1

[0040] see Figure 1-5, a multi-station tooth-making fixture for tools used in the sugar industry, which includes an indexing plate 7, a transition plate 6 is fixedly installed on the top of the indexing plate 7, and the top of the transition plate 6 is uniform along the circumferential direction. The cloth is provided with a plurality of stations, and each station is correspondingly arranged with a set of fixtures; each set of fixtures includes a set of self-locking booster mechanism, and the booster mechanism includes a workpiece positioning plate 12, a workpiece pad plate 11, pressing plate 2, backing plate 9, oil cylinder 10 and slide block 8; two hydraulic support cylinders 13 are installed above the workpiece positioning plate 12; contact bolts are all installed on each of the hydraulic support cylinders 13 14; the left and right directions of the workpiece backing plate 11 are respectively equipped with a positioning plate 19 and a guide block 17; the guide block 17 is ...

Embodiment 2

[0055] The method for clamping workpieces by using any one of the multi-station tooth-making fixtures for tools used in the sugar industry includes the following steps:

[0056] Step 1: In the initial state, the oil cylinder 10 is in the retracted state, and the pressure plate 2 is in the loosened state; firstly, the index plate 7 is manually operated to rotate to the loading and unloading position, and then the operator manually pulls the spring rocker 15 with the right hand to make the push rod 18 go toward Retract, put the workpiece 1 under the pressure plate 2 with the left hand; then release the left and right hands at the same time and then hold the workpiece 1 to pull the workpiece 1 away from the rotation center, so that the workpiece 1 can be positioned in the width direction; after loosening the workpiece 1 due to the length The effect of direction compression spring clamping, the workpiece 1 has been fixed in a specific position and cannot be moved;

Abstract

The invention provides a multi-station tooth-making fixture and a clamping method for cutting tools used in the sugar industry. Reset mechanism, positioning clamping and releasing mechanism in the length direction of the workpiece. The mouse-tooth indexing plate can ensure the accuracy of indexing at any integer degree, the transition plate can convert the oil circuit of the turntable plane to its own outer circle, and the total force ratio of the self-locking clamping mechanism 7:1, respectively composed of a set of self-locking booster mechanism and a set of lever booster mechanism, the press plate reset mechanism is a set of tension spring reset mechanism shared by the 3-station press plate. The multi-station tooth-making scheme of the tool used in the sugar industry of the present invention adopts the scheme of 3 rotating stations instead of 3 parallel arrays, which greatly reduces the occupied space of the equipment and reduces the cost of equipment procurement.

Description

technical field [0001] The invention relates to a multi-station tooth-making fixture and method for a tool used in the sugar industry, and belongs to the technical field of tool clamping and processing. Background technique [0002] my country is the main sugar producing and consuming country in the world. Sugarcane and sugar beet are the two most widely used raw materials in the sugar industry. Cane sugar production areas are mainly in Guangxi, Yunnan and Guangdong, while beet sugar production areas are mainly in Xinjiang, Heilongjiang and Inner Mongolia. At present, the overall technology and equipment level of my country's sugar industry is still relatively backward, the production cost is high, the product quality is unstable, the comprehensive utilization efficiency is low, and the pollution is serious. [0003] In the process of using sugar beets, it is necessary to use a special chip cutter to cut the beets into thin and uniform slices to facilitate the precipitation...
