[0003] At present, the quick-change structure of the parts press-fitting station adopts T-block insertion. That is, the tooling quick-change plate is inserted into the tooling fixed plate through the T-block, and then the position is fixed by the plunger. Summary of the invention
[0004] The utility model aims to provide a tooling quick-change structure for a parts press-fitting station which is different from the T-shaped block insertion.
[0005] In order to achieve this purpose, the technical solution of the utility model is as follows: a tooling quick-change structure for a part press-fitting station, comprising: a tooling fixed plate and a tooling quick-change plate below the tooling fixed plate; a fixed plate groove extending along the front-to-back direction is formed on the top surface of the tooling fixed plate, the fixed plate groove has a groove front section, a groove middle section and a groove rear section, the groove middle section is through-connected from top to bottom, a sliding slider is provided inside the fixed plate groove, the sliding slider has a slider front section sliding along the groove front section and a slider rear section sliding along the groove rear section ; An L-shaped hook is formed on the top surface of the tooling quick-change plate, and the L-shaped hook passes upward through the middle section of the groove. The tooling quick-change plate is suspended on the front section of the slider through the L-shaped hook, thereby locking the tooling fixed plate and the tooling quick-change plate; the sliding slider is displaced forward, and since the middle section of the groove limits the front and rear displacement of the L-shaped hook, the front section of the slider and the L-shaped hook are misaligned up and down, and the tooling quick-change plate automatically falls due to its gravity, thereby unlocking the tooling fixed plate and the tooling quick-change plate.
[0006] As a preferred solution for the quick-change structure of the tooling at the part press-fitting station, the portion of the top surface of the front section of the slider that matches with the L-shaped hook is a slope that is higher in the front and lower in the back.
[0007] As a preferred solution for the quick-change structure of the tooling at the part press-fitting station, the front end of the fixed plate groove is closed, and a spring is provided between the front section of the slider and the front end of the fixed plate groove.
[0008] As a preferred solution for the tooling quick-change structure of the part pressing station, the tooling fixed plate and the tooling quick-change plate are both square structures, the bottom surface of the tooling fixed plate has locating pins at one set of diagonal positions, and the top surface of the tooling quick-change plate has bushings at one set of diagonal positions and the bushings are opposite to the locating pins, and the locating pins cooperate with the axial holes of the bushings to achieve rapid positioning of the tooling fixed plate and the tooling quick-change plate.
[0009] As a preferred solution for the quick-change structure of the tooling at the part pressing station, the rear end of the fixed plate slot is an open end, and in a locked state, a portion of the rear section of the slider is at the rear section of the slot, while the other portion is behind the rear section of the slot and exposed outside the tooling fixed plate.
[0010] Compared with the prior art, the beneficial effects of the present invention are at least as follows: through the design of the sliding block and the L-shaped hook, the rapid assembly and disassembly of the tooling fixing plate and the tooling quick-change plate can be achieved; through the design of the positioning pin and the sleeve, the accurate positioning of the tooling fixing plate and the tooling quick-change plate can be achieved; under the premise of controlling the processing difficulty, the precision requirements of the tooling are guaranteed, and the simplicity of the changeover is also guaranteed.

[0016] The present invention is further described in detail below through specific implementations in combination with the accompanying drawings. It should be noted that the description of these implementations is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0017] See also Figure 1, shown in the figure is a quick-change structure for tooling in a parts press-fitting station. The quick-change structure for tooling in a parts press-fitting station is used for press-fitting parts such as stators on automobile air-conditioning compressors and powertrains, shaft systems, and housing assembly lines.
[0018] The tooling quick-change structure of the part press-fitting station includes: a tooling fixing plate 1 and a tooling quick-change plate 2 below the tooling fixing plate 1. The tooling fixing plate 1 is fixed. The tooling fixing plate 1 abuts against the tooling quick-change plate 2. A pressing head 3 is provided below the tooling quick-change plate 2.
[0019] See also Figure 2 , the figure shows the tooling fixing plate 1. A long fixing plate groove 11 is formed on the top surface of the tooling fixing plate 1. The fixing plate groove 11 extends along the front-to-back direction. The front end of the fixing plate groove 11 is closed, while the rear end of the fixing plate groove 11 is open. The fixing plate groove 11 has a groove front section 111, a groove rear section 113, and a groove middle section 112 between the groove front section 111 and the groove rear section 113. The groove front section 111, the groove middle section 112, and the groove rear section 113 are all straight line sections and have a common center line. The widths of the groove front section 111, the groove middle section 112, and the groove rear section 113 are in the following relationship: the width of the groove middle section 112>the width of the groove front section 111>the width of the groove rear section 113. The tooling fixing plate 1 is through-through at the position of the groove middle section 112.
[0020] See also Figure 2 , the fixed plate slot 11 contains a long sliding slider 12. The sliding slider 12 has a slider front section 121 and a slider rear section 122. The slider front section 121 and the slider rear section 122 are both straight segments and have a common center line. The slot front section 111 slides along the slider front section 121. The slider rear section 122 slides along the slot rear section 113. There is a spring 13 between the slider front section 121 and the front end of the fixed plate slot 11. Locked state: the slider front section 121 abuts against the rear end surface of the slot middle section 112. At this time, one part of the slider front section 121 is at the slot front section 111, and the other part is at the slot middle section 112. There is a sliding distance between the slider front section 121 and the front end of the fixed plate slot 11, and one part of the slider rear section 122 is at the slot rear section 113, and the other part is behind the slot rear section 113 and exposed outside the tooling fixed plate 1.
[0021] See also Figure 3 and Figure 4, an L-shaped barb 21 is formed on the top surface of the tooling quick-change plate 2. The L-shaped barb 21 is located at the middle section 112 of the groove and on the left and right sides of the front section 121 of the slider. The L-shaped barb 21 has a barb transverse portion 211 and a barb vertical portion 212. Locked state: the barb transverse portion 211 is directly above the front section 121 of the slider. The front section 121 of the slider supports the tooling quick-change plate 2 through the barb transverse portion 211. That is, the tooling quick-change plate 2 is suspended on the front section 121 of the slider through the L-shaped barb 21. The front end face and the rear end face of the middle section 112 of the groove are used to limit the displacement of the barb transverse portion 211 in the front and rear directions. Lower, the mating surface of the barb transverse portion 211 and the front section 121 of the slider is an inclined surface, and the inclined surface is higher in the front and lower in the back.
[0022] See also Figure 5 , unlocked state: a forward force is applied to the sliding slider 12 (preferably, the forward force is applied to another part of the slider rear section 122), and the slider front section 121 overcomes the backward force of the spring 13 and moves forward, while the front and rear positions of the L-shaped barb 21 remain unchanged. At this time, the slider front section 121 and the barb transverse portion 211 of the L-shaped barb 21 are staggered in the up and down directions, that is, the slider front section 121 can no longer support the tooling quick-change plate 2 through the barb transverse portion 211, and the tooling quick-change plate 2 automatically falls due to its gravity, thereby separating the tooling fixed plate 1 from the tooling quick-change plate 2.
[0023] It should be noted that the barb transverse portion 211 is staggered left and right from the slider rear section 122 , so as not to affect the automatic falling of the tooling quick-change plate 2 when the slider rear section 122 enters the slot middle section 112 .
[0024] Preferably, the tool fixing plate 1 and the tool quick-change plate 2 are both square structures. The bottom surface of the tool fixing plate 1 has a positioning pin 4 at one of the diagonal positions, and the top surface of the tool quick-change plate 2 has a bushing 5 at one of the diagonal positions. The positioning pin 4 cooperates with the axial hole of the bushing 5 to achieve accurate positioning in the locked state. In addition, the design of the positioning pin 4 and the bushing 5 can further reduce the manufacturing difficulty. When changing the mold, only the holes need to be aligned, which is convenient for operation and reduces the changeover time.
[0025] The above only expresses the implementation mode of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
