Abstract

The utility model discloses U -shaped bolt heat treatment process's centre gripping frock, include two vertical grip blocks, be equipped with the connecting piece between two grip blocks, set up the vertical draw -in groove that inserts the U -shaped bolt on the grip block, vertical screw is seted up to the bottom of grip block, be equipped with the adjusting bolt who presss from both sides tight U -shaped bolt in the screw. In inserting vertical draw -in groove with multiunit U type bolt, fix with the centre gripping frock, tighten adjusting bolt after, each position of U type bolt is all under the restriction of centre gripping frock. During thermal treatment U type bolt can only with the synchronous inflation of frock, contract in step again during the cooling and get back to original state. Unscrew adjusting bolt behind the thermal treatment, loosen the U -shaped bolt, can follow and take out U type bolt in the vertical draw -in groove. The utility model discloses an easy operation is convenient, and safe and reliable can solve the deformations problems among the U type bolt heat treatment process.

Description

The clamping tooling of U bolt heat treatment process

Technical field

The utility model relates to a kind of clamping tooling, is specifically related to a kind of clamping tooling of U bolt heat treatment process.

Background technology

U bolt, i.e. U-bolts, criteria of right and wrong part, so be shaped as U-shaped also referred to as U-bolt, two has screw thread to be combined with nut, is mainly used in fixing tube if water pipe or tablet are as the leaf spring of automobile, due to the mode of its mounting article as people horseback, therefore be called U-bolts.

U-bolt is bending in forming process, because there being internal stress to exist, when heat treatment U-bolt distortion serious, main deformation is: U-bolt bipod fork, closed, warpage etc. Product after distortion can not meet user's instructions for use at all, only has employing manually to correct, not only waste time and energy, and inefficiency, the product quality after rectification is also difficult to ensure. Therefore, need to consider to solve the problem on deformation in U-bolt heat treatment process.

Utility model content

The purpose of this utility model is to provide a kind of clamping tooling of U bolt heat treatment process, under the constraint by clamping tooling and restriction, prevents the distortion of U bolt after heat treatment.

For achieving the above object, the technical solution of the utility model is: the clamping tooling of U bolt heat treatment process, two vertical grip blocks are comprised, between two grip blocks, be provided with connector, on described grip block, offer the vertical draw-in groove that inserts U bolt, the bottom of described grip block offers vertical screw, is provided with the adjusting bolt that clamps U bolt in described screw.

While adopting technique scheme, will organize U-bolt more and insert in vertical draw-in groove, and be fixed with clamping tooling, and tighten after adjusting bolt, each orientation of U-bolt is all under the restriction of clamping tooling. When heat treatment, U-bolt can only be synchronizeed and expand with frock, synchronous and get back to initial state again when cooling. After heat treatment, unscrew adjusting bolt, unclamp U bolt, can from vertical draw-in groove, take out U-bolt. Of the present utility model simple to operation, safe and reliable, can solve the problem on deformation in U-bolt heat treatment process.

Further, the end of described vertical draw-in groove is circular arc. Be arranged to circular arc, can increase the laminating degree of U bolt and vertical draw-in groove end, can further suppress the deformation of U bolt.

Further, the end of described adjusting bolt is provided with the pad of arc. Compare adjusting bolt end and contact with the direct of U bolt, can increase and the contact area of U bolt by the pad of arc.

Further, described connector is positioned at the middle part of grip block. Connector is fixed on to the middle part of two grip blocks, can force balance, avoid deformation.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

Fig. 1 is the structural representation of the clamping tooling embodiment of the utility model U bolt heat treatment process;

Fig. 2 is the plan structure schematic diagram of Fig. 1.

Brief description of the drawings: grip block 1, connector 2, vertical draw-in groove 3, adjusting bolt 4, U bolt 5.

Detailed description of the invention

As depicted in figs. 1 and 2, the clamping tooling of the utility model U bolt heat treatment process, has comprised that two vertical 1, two grip blocks 1 of grip block are identical. The connector 2 that is welded with metal between two grip blocks 1, connector 2 is positioned at the middle part of grip block 1. Connector 2 is fixed on to the middle part of two grip blocks 1, can force balance, avoid deformation. On grip block 1, offer the vertical draw-in groove 3 that has inserted U bolt 5, the end of vertical draw-in groove 3 is circular arc. Be arranged to circular arc, can increase the laminating degree of U bolt 5 and vertical draw-in groove 3 ends, can further suppress the deformation of U bolt 5. The bottom of grip block 1 offers vertical screw, is provided with the adjusting bolt 4 that clamps U bolt 5 in screw. The end of adjusting bolt 4 is provided with the pad of arc. Compare adjusting bolt 4 ends and contact with the direct of U bolt 5, can increase and the contact area of U bolt 5 by the pad of arc.

While adopting technique scheme, six groups of U-bolts 5 are inserted in vertical draw-in groove 3, fixed with clamping tooling, tighten after adjusting bolt 4, each orientation of U-bolt 5 is all under the restriction of clamping tooling. When heat treatment, U-bolt 5 can only be synchronizeed and expand with frock, synchronous and get back to initial state again when cooling. After heat treatment, unscrew adjusting bolt 4, unclamp U bolt 5, can from vertical draw-in groove 3, take out U-bolt 5. Of the present utility model simple to operation, safe and reliable, can solve the problem on deformation in U-bolt 5 heat treatment processes.

Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
