Adjustable sizing block

Abstract

The invention discloses an adjustable sizing block, comprising a steel wire check ring, a locking block, a locking bolt, a base, spanner holes, a nut sleeve and a groove face top block. The steel wire check ring is arranged in the groove face top block, and the nut sleeve is arranged on the base. Four spanner holes are uniformly distributed along the circumference of the nut sleeve (only one is drawn in the figure) so that the nut sleeve can be rotated by a matched spanner to ascend or descend a slotted surface press block. When the nut sleeve is rotated to an ideal position, the locking bolt is rotated by using the other end of the matched spanner to tightly press the locking block on the thread part of the sleeve, wherein the inner face of the locking block is provided with screw threads with the same specification as that of the sleeve, thereby the slotted surface press block is prevented from gliding downwards due to workpiece vibration or other conditions. In order to fix the base with a boring mill worktable, the two sides of the base are provided with elongated slots for installing T-shaped bolts.

Description

technical field [0001] The invention relates to a tooling, in particular to an adjustable pad iron. Background technique [0002] For metal processing plants or machining workshops that mainly process external processing, most of the processed parts have the following characteristics: the quantity is not large enough to form a batch, the variety does not have commonality, the processing difficulty is relatively large, and customers are unwilling to process... …This puts forward relatively strict requirements on the fixture design: it is impossible to manufacture expensive special fixtures, the manufactured fixtures should be as simple as possible and easy to operate and maintain, and the manufacturing cycle should be as short as possible. [0003] Most of the external parts in the applicant's machining workshop are connection boxes or reducer boxes, and these two boxes must be bored on the T125 type boring machine in the workshop. Depend on figure 1 It can be seen that eac...

Problems solved by technology

However, with the use of the operator, complaints follow. For example, the parallel iron cannot be fixed with the boring machine table, and it is very easy to run away or even hit it during the process of placing the box with the crane. If several parallel irons are used This is especially true for combined use; after the box is placed, in the process of knocking on each wedge-shaped iron to adjust the height of the box, several positions interfere with each other, and often take care of one and lose the other, and often have to adjust repeatedly, etc.

In other words, the old-style fixtures have problems such as low positioning accuracy, unreliable clamping, low efficiency, and high labor intensity for workers.
