Description

Technical Field

[0001] The utility model relates to the technical field of jigs for preventing bending during heat treatment of springs, in particular to a jig for preventing bending during heat treatment of springs. Background Art

[0002] The spring heat treatment anti-bending fixture can avoid deformation of the spring during heat treatment and quenching, ensuring the spring's shape.

[0003] For example, a heat treatment anti-deformation jig with the announcement number "CN220951927U" is provided with a fixed block on the right side wall of the clamping block in the adjustment component of the placement mechanism, which is connected by the left mounting block and the right mounting block in the installation mechanism to realize simultaneous processing of multiple jigs, greatly reducing the working time of the processing personnel. It is quickly positioned by the positioning component in the placement mechanism. At the same time, the adjustment component can quickly adjust the spacing of the clamping blocks, which is suitable for use with workpieces of different sizes. However, in the use of the heat treatment anti-bending jig, only the workpieces within the space can be used. Although heat treatment of workpieces of multiple specifications is achieved, the clamping positioning is fixed with multiple bolts, which is not convenient for disassembly and assembly of the heat treatment anti-bending jig, increases the difficulty of using the heat treatment anti-bending jig, and makes the heat treatment anti-bending jig have usage limitations. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the use of the heat treatment anti-bending jig is difficult and the heat treatment anti-bending jig has usage limitations, and to propose a jig for heat treatment anti-bending of springs.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A jig for preventing spring bending during heat treatment is designed, comprising a base plate and a bracket. The left side of the base plate is fixedly connected to the right bottom of the bracket, the left top of the bracket is connected to a top plate, the inner wall of the top plate is connected to a fixing structure, the inner wall of the fixing structure is connected to the outer wall of the bracket, and the inner wall of the bracket is connected to a supporting structure.

[0007] Preferably, the fixing structure includes a screw and a handle, the outer wall of the screw is threadedly connected to the inner wall of the top plate, the top of the screw is fixedly connected to the bottom of the handle, and the bottom of the outer wall of the screw is rotatably connected to a splint.

[0008] Preferably, the inner wall of the splint is slidably connected to the outer wall of the bracket.

[0009] Preferably, the support structure includes a round rod and a straight plate, the outer wall of the round rod is plugged into the lower inner wall of the bracket, the left side of the round rod is fixedly connected to the right side of the straight plate, and the front and rear sides of the outer wall of the straight plate are respectively threaded with bolts.

[0010] Preferably, the right side of the straight board fits in with the left side of the bracket.

[0011] Preferably, the right side of the outer wall of the bolt is threadedly connected to the left circular opening of the bracket.

[0012] The utility model proposes a jig for heat treatment and anti-bending of springs, which has the beneficial effect of: the screw is rotated downward through the top plate by cooperating with the handle in the fixed structure, and the rotating screw carries the clamping plate downward on the outer wall of the bracket, so that the bottom of the clamping plate is clamped with the top of the spring, and then the fixed spring is heat treated, which changes the original multi-point bolt fixing form, reduces the difficulty of using the heat treatment anti-bending jig, and eliminates the usage limitations of the heat treatment anti-bending jig.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-4 : In this embodiment, a jig for preventing spring bending during heat treatment includes a base plate 1 and a bracket 4. The left side of the base plate 1 is fixedly connected to the right bottom of the bracket 4. The top left side of the bracket 4 is connected to a top plate 5. The inner wall of the top plate 5 is connected to a fixed structure 2. The inner wall of the fixed structure 2 is connected to the outer wall of the bracket 4. The inner wall of the bracket 4 is connected to a support structure 3.

[0021] The fixing structure 2 includes a screw 201 and a handle 202. The outer wall of the screw 201 is threadedly connected to the inner wall of the top plate 5. The screw 201 is subjected to force to rotate up and down through the inner wall of the top plate 5. The top of the screw 201 is fixedly connected to the bottom of the handle 202. The handle 202 is convenient for driving the screw 201 to rotate. The bottom of the outer wall of the screw 201 is rotatably connected to a splint 203. The bottom of the outer wall of the screw 201 is subjected to force to rotate through the left bearing at the top of the splint 203. The inner wall of the splint 203 is slidably connected to the outer wall of the bracket 4. The splint 203 is subjected to force to slide up and down through the outer wall of the bracket 4.

[0022] By using the handle 202 in the fixing structure 2, the screw 201 is rotated downward through the top plate 5. The rotating screw 201 moves downward with the clamping plate 203 on the outer wall of the bracket 4, so that the bottom of the clamping plate 203 is clamped with the top of the spring. The fixed spring can then be heat-treated, which changes the original multi-point bolt fixing form, reduces the difficulty of using the heat treatment anti-bending jig, and eliminates the limitations of the use of the heat treatment anti-bending jig.

[0023] The supporting structure 3 includes a round rod 301 and a straight plate 302. The outer wall of the round rod 301 is plugged into the lower part of the inner wall of the bracket 4. The left side of the round rod 301 is fixedly connected to the right side of the straight plate 302. The front and rear sides of the outer wall of the straight plate 302 are respectively threaded with bolts 303. The bolts 303 fix the straight plate 302 and the bracket 4. The right side of the straight plate 302 fits against the left side of the bracket 4. The right side of the outer wall of the bolt 303 is threadedly connected to the left round mouth of the bracket 4.

[0024] Working principle:

[0025] Spring heat treatment anti-bending fixture spring support:

[0026] Insert the round rod 301 corresponding to the inner diameter of the spring into the inner wall of the bracket 4 from left to right until the right side of the straight plate 302 fits with the left side of the bracket 4. Then, thread the bolt 303 through the straight plate 302 from left to right and connect it with the left side of the bracket 4 to complete the fixation of the round rod 301. Then, put the spring on the outer wall of the round rod 301.

[0027] Spring heat treatment anti-bending fixture spring fixation:

[0028] Then, the handle 202 is used to rotate the screw 201 downward through the top plate 5. The rotating screw 201 moves the clamping plate 203 downward on the outer wall of the bracket 4, so that the bottom of the clamping plate 203 is clamped with the top of the spring. The fixed spring is then heat-treated. Without installing the round rod 301, the workpiece is placed on the top of the bottom plate 1 and then fixed by the clamping plate 203 to complete the fixation of the workpiece other than the spring.

[0029] Example 2:

[0030] See also Figure 1-4 : In this embodiment, a jig for preventing spring bending during heat treatment also includes a baffle 6, the outer wall of the baffle 6 is plugged into the top slot of the bracket 4.

[0031] Working principle:

[0032] After the workpiece is installed, the baffle 6 is inserted into the bracket 4 from top to bottom, so that the baffle 6 isolates the fixed workpiece and the screw 201 on the left side to prevent the screw from being overheated during the heat treatment of the workpiece.
