Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a positioning fixture for a transfer mounting base. Background Technology

[0002] As an important intermediate carrier component in mechanical equipment or production lines, the transfer mounting base is usually a non-standard part, which needs to be specially designed and processed according to the interface and functional requirements of the specific equipment.

[0003] Figure 1 The image shows one type of transfer mount. This transfer mount has a circular groove with a through hole in the center. It also has mounting holes located next to the circular groove. The mounting holes and the circular groove mate to secure other components. In CNC machining, this special transfer mount typically uses a vise to clamp the workpiece. The vise clamps both sides of the workpiece. Because the sides of the transfer mount need to be machined, only two sides can be machined at a time after clamping the transfer mount with the vise. After machining, the workpiece position is changed and re-clamped to machine the other two sides. This method has obvious drawbacks: firstly, the clamping process is cumbersome, making it difficult to ensure consistent position between the two clamping operations; secondly, the second clamping clamps the two already machined sides, which can easily scratch or wear the workpiece surface. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by designing a positioning fixture for a transfer mounting base, which solves the problems of cumbersome steps and easy scratching during the clamping process of the transfer mounting base.

[0005] The technical solution of this utility model to achieve the above objectives is a positioning fixture for a transfer mounting base, comprising: The tooling base has a positioning platform for placing a transfer mounting base to be processed. One side of the positioning platform protrudes upward to form a positioning part for interlocking with the bottom of the transfer mounting base to be processed. A threaded hole is provided in the center of the positioning part. The positioning post has a first mounting hole and a second mounting hole on the positioning platform. The first mounting hole and the second mounting hole are symmetrically distributed with respect to the positioning part. The positioning post is vertically installed in the first mounting hole or the second mounting hole. The position of the positioning post is adapted to the position of the bottom circular groove of the transfer mounting seat to be processed.

[0006] Preferably, the positioning post is inserted into the first mounting hole or the second mounting hole and is interference-fitted with the first mounting hole or the second mounting hole.

[0007] Preferably, the first mounting hole and the second mounting hole are threaded holes, and the positioning pin is threadedly connected to the first mounting hole or the second mounting hole.

[0008] Preferably, the top surface of the positioning post has an internal hexagonal hole.

[0009] Preferably, the bottom of both sides of the tooling base protrudes outward to form a support portion, and the support portion is provided with at least one third mounting hole.

[0010] Preferably, the third mounting hole is a smooth hole or a threaded hole.

[0011] Preferably, the positioning platform has two threaded holes, which correspond to the first mounting hole and the second mounting hole respectively, and are located on the side of the first mounting hole and the second mounting hole away from the positioning part respectively.

[0012] Preferably, a pressure plate is provided above the positioning part for pressing and fixing the transfer mounting seat to be processed onto the tooling base.

[0013] Its advantages over existing technologies are: This utility model's positioning fixture has advantages such as simple clamping and strong compatibility. After the transfer positioning seat to be processed is placed on the positioning platform, the positioning part on the fixture base will embed into the groove at the bottom of the transfer positioning seat and provide support for the groove bottom. The positioning pin can be inserted into the corresponding hole at the bottom of the transfer positioning seat to position the transfer positioning seat and prevent the transfer positioning seat from deflecting during processing. Finally, the bolt is threaded through the threaded hole on the positioning part of the transfer positioning seat and threadedly connected to it, thereby fixing the transfer mounting seat on the positioning fixture. One clamping can simultaneously meet the processing requirements of four sides of the transfer mounting seat, and the positioning fixture will not scratch or wear the sides of the transfer positioning seat.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Example 1 like Figure 2 As shown, a preferred embodiment of this utility model provides a positioning fixture for a transfer mounting base 4. The positioning fixture mainly includes a fixture base 1 and a positioning post 2. The fixture base 1 is used to place and support the transfer positioning base, and the positioning post 2 is used to position the transfer positioning base and prevent it from rotating.

[0018] For details, see Figure 3 The tooling base 1 has a cubic structure. A positioning platform 11 is formed on the upper surface of the tooling base 1 to support the transfer mounting base 4 and raise the transfer mounting base 4 to a certain height so that the machining head can process the tooling base 1. On the side of the positioning platform 11 near its length, a circular positioning part 101 is formed by protruding upward. The size of the positioning part 101 is adapted to the size of the groove at the bottom of the transfer mounting base 4, which can support the bottom of the groove and prevent the hollow area from being deformed by force during the processing.

[0019] A bolt hole 1011 is provided in the central area (i.e., the area where the center is located) of the positioning part 101. The bolt hole 1011 is a threaded hole. After the transfer positioning seat is placed on the positioning platform 11, the positioning part 101 will be embedded into the groove at the bottom of the transfer positioning seat. Then, the bolt with the cap is passed through the transfer mounting seat 4 and threadedly connected to the threaded hole on the positioning part 101, thereby initially fixing the transfer mounting seat 4.

[0020] like Figure 3 As shown, on the tooling base 1, two mounting holes are provided on the side of the positioning platform 11 away from the positioning part 101, namely the first mounting hole 102 and the second mounting hole 103. The first mounting hole 102 and the second mounting hole 103 are located on both sides of the positioning platform 11 in the width direction and are symmetrically distributed with respect to the positioning part 101.

[0021] In this embodiment, both the first mounting hole 102 and the second mounting hole 103 are blind holes, and the blind holes are smooth holes. One positioning post 2 is provided, and the positioning post 2 can be inserted into the first mounting hole 102 to form an interference fit therewith, and can also be inserted into the second mounting hole 103 to form an interference fit therewith.

[0022] There are two styles of transfer positioning seats, and the difference between these two styles lies in the different positions of the circular holes at the bottom of the transfer positioning seats, which are approximately symmetrically distributed. For details, please refer to Figure 1 Therefore, by selectively inserting the positioning post 2 into the first mounting hole 102 or the second mounting hole 103, the positioning requirements of the two types of transfer positioning seats can be met.

[0023] Referring to Figure 2 , Figure 3 , on the tooling base 1, two bolt holes 1011 are further provided on the positioning platform 11, and both of the two bolt holes 1011 are threaded holes. The two bolt holes 1011 are in one-to-one correspondence with the first mounting hole 102 and the second mounting hole 103 respectively, and the first mounting hole 102 and the second mounting hole 103 are respectively located between the two bolt holes 1011 and the positioning portion 101. The positions of the two bolt holes 1011 correspond to the positions of the two bolt holes on the transfer positioning seat.

[0024] Referring to Figure 4 , after the transfer positioning seat is placed on the positioning platform 11, the positioning portion 101 is fixed to the transfer mounting seat 4 by bolts, then bolts pass through the bolt holes on the transfer mounting seat 4 and are threadedly connected with the above two bolt holes 1011 on the tooling base 1. Through three bolts, three-point positioning can be realized, and the transfer mounting seat 4 can be stably fixed on the tooling base 1.

[0025] As shown in Figure 2 , supporting portions 104 are formed protruding outward at the bottoms of both sides of the tooling base 1, so that the cross-sectional shape of the positioning tooling presents a "convex" shape. The supporting portions 104 located on both sides of the tooling base 1 can provide stable support for the tooling base 1. Among the two supporting portions 104, one supporting portion 104 is provided with one mounting hole, that is, the third mounting hole 1041. The other supporting portion 104 is provided with two third mounting holes 1041, and the three third mounting holes 1041 are distributed in a triangle. The third mounting hole 1041 is a smooth hole or a threaded hole. After a bolt passes through the third mounting hole 1041, it is threadedly connected with a platform plate on a machine tool, thereby fixedly mounting the positioning tooling on the platform plate.

[0026] In other embodiments, two or more mounting holes may also be provided on each supporting portion 104, and the number depends on the size of the positioning tooling.

[0027] Example 2 The difference in this embodiment is that both the first mounting hole 102 and the second mounting hole 103 are blind holes, and these blind holes are threaded holes. Figure 5 As shown, a hexagonal socket 201 is provided on the top surface of the positioning post 2, and a thread is provided on the outer edge surface of the positioning post 2. Therefore, the lower end of the positioning post 2 can be threadedly connected to the first mounting hole 102 or the second mounting hole 103. By inserting a wrench into the hexagonal socket 201, the positioning post 2 can be rotated to quickly insert the positioning post 2 into the first mounting hole 102 or the second mounting hole 103.

[0028] Example 3 like Figure 6 As shown, in this embodiment, in order to stably fix the transfer mounting base 4 to the positioning part 101 on the tooling base 1, a pressure plate 3 is provided above the positioning part 101. The size of the pressure plate 3 is much smaller than the size of the transfer positioning base. The pressure plate 3 presses the transfer mounting base 4 tightly onto the positioning part 101, and then bolts pass through the pressure plate 3 and the transfer mounting base 4 to connect with the bolt holes 1011 on the positioning part 101.

[0029] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
