Description

Technical Field

[0001] This application relates to the field of industrial production technology, specifically a rotary gear shifting mechanism. Background Technology

[0002] In industrial production, molds are used to shape workpieces. For example, when producing silicone oil housings, molds are often used to shape the silicone oil housings. Since silicone oil housings are commonly used in the automotive industry and are widely used, they often need to be produced in batches. When producing workpieces in batches, a rotary shifting mechanism is required. This structure can quickly adjust the position of the mold to meet the needs of processing multiple workpieces with the same set of molds.

[0003] Existing rotary wheel positioning mechanisms typically include a mold, a mounting plate, and a rotary wheel. The mold is fixedly connected to the mounting plate, while the rotary wheel is usually fixedly mounted on the top of the fixed plate. When the position of the mold needs to be adjusted, the mounting plate can be pushed.

[0004] Although the above structure enables mold repositioning, in order to ensure stable displacement, the number of rotating wheels is usually four. If at least four sets of rotating wheels are installed at the bottom of the mounting plate, they will occupy a large area. Furthermore, when the mold is processing the workpiece, the workpiece cannot be positioned, which will affect the quality of workpiece processing to some extent. Therefore, it is necessary to provide a rotating wheel repositioning mechanism to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a rotary wheel positioning mechanism that solves the problem that the rotary wheel positioning mechanism cannot position the mold when the mold is processing the workpiece.

[0007] The technical solution adopted by this application to solve its technical problem is: a rotary wheel switching mechanism, comprising: a rear plate; a slide rail, which is fixedly installed on both sides of the rear plate; a slider, which is slidably installed on the slide rail; a valve block, which is fixedly installed on the slider, with a hydraulic cylinder fixedly installed at the bottom of the valve block, and the output end of the hydraulic cylinder passing through one side of the rear plate; at least two sets of positioning mechanisms, which are arranged on both sides of the slider, each positioning mechanism including a fixed plate fixedly installed on one side of the slider, a support block fixedly installed on one side of the fixed plate, and a connecting rod fixedly installed on the top of the support block; A main positioning block is fixedly installed on the top of one side of the connecting rod, and the main positioning block is hollow inside to form a first chamber; a protruding block is integrally disposed on one side of the main positioning block, and the protruding block is hollow inside to form a second chamber, which communicates with the first chamber; a first driving block is located in the first chamber, and a first spring is fixedly installed between the first driving block and the connecting rod; a first clamping block is fixedly installed on the side of the first driving block away from the connecting rod, and the first clamping block is located in the second chamber.

[0008] Furthermore, a clamping pad is fixedly installed at the other end of the first clamping block, and the surface of the clamping pad is arc-shaped.

[0009] Furthermore, a secondary positioning block is integrally provided on both sides of the main positioning block. The interior of the secondary positioning block is hollow and forms a third chamber. The third chamber communicates with the first chamber. A first inclined surface is provided on both sides of the first driving block. A second driving block is provided on both sides of the first driving block. A second inclined surface is provided on the second driving block. The first inclined surface and the second inclined surface are in contact.

[0010] Furthermore, a third clamping block is fixedly installed on both sides of the second driving block. One section of the third clamping block extends into the third chamber. The inner diameter of the third chamber is adapted to the inner diameter of the second driving block. A second spring is fixedly installed on the side of the third clamping block away from the second driving block, and a second clamping block is fixedly installed on the other side of the second spring.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figures 1-2 As shown, this application provides a rotary wheel switching mechanism, including a rear plate 1, which is the support part of the rotary wheel switching mechanism and provides support for subsequent mold switching. Slide rails 2 are fixedly installed on both sides of the rear plate 1, and sliders 21 are slidably installed on the slide rails 2.

[0026] A valve block 4 is fixedly installed on the slider 21. When the slider 21 slides on the slide rail 2, it is suitable to drive the valve block 4 to slide synchronously. A hydraulic cylinder 3 is fixedly installed at the bottom of the valve block 4. The output end of the hydraulic cylinder 3 passes through one side of the rear plate 1. So when the valve block 4 slides under the drive of the slider 21, the hydraulic cylinder 3 will slide synchronously. Through the cooperation of the slider 21 and the slide rail 2, the rotary wheel is replaced, which occupies less space and facilitates the adjustment of the position of the valve block 4.

[0027] In industrial production, workpieces are typically placed on valve block 4 and then processed using a mold. Although the position of valve block 4 can be adjusted using slider 21, the workpiece cannot be fixed when it is on valve block 4. To solve this problem, such as... Figure 1 , Figures 3-4 As shown, positioning mechanisms 5 are provided on both sides of the slider 21. The positioning mechanism 5 includes a fixed plate 51 fixedly installed on one side of the slider 21, a support block 52 fixedly installed on one side of the fixed plate 51, a connecting rod 53 fixedly installed on the top of the support block 52, and a main positioning block 54 fixedly installed on the top of one side of the connecting rod 53. The main positioning block 54 is hollow inside and forms a first chamber.

[0028] A protruding block 541 is integrally provided on the side of the main positioning block 54 away from the connecting rod 53. The protruding block 541 is hollow and forms a second chamber. The first chamber is connected to the second chamber. A first driving block 56 is provided on the side of the first chamber near the second chamber. The width of the side of the first driving block 56 away from the connecting rod 53 is greater than the width of the second chamber. The first driving block 56 is trapezoidal. A first spring 55 is fixedly installed between the first driving block 56 and the connecting rod 53. Due to the elastic force of the first spring 55, one side of the first driving block 56 abuts against the side of the first chamber away from the connecting rod 53.

[0029] A first clamping block 59 is fixedly installed on the side of the first drive block 56 away from the connecting rod 53. The first clamping block 59 is located in the second chamber. A clamping pad 510 is fixedly installed on the other end of the first clamping block 59. It should be noted that the protruding block 541 and the first clamping block 59 are both located on the valve block 4. When the workpiece is located on the valve block 4, its two ends are suitable for contacting the clamping pad 510. If the width of the valve block 4 is greater than the distance between the clamping pads 510 on both sides of the valve block 4, the workpiece will exert a squeezing effect on the clamping pad 510, so that the clamping pads 510 on both sides move in a direction away from each other, and the first spring 55 is compressed. Thus, the first clamping block 59 and the clamping pad 510 can clamp the workpiece.

[0030] Meanwhile, in order to facilitate the workpiece to reach the clamping pad 510, the surface of the clamping pad 510 is arc-shaped. During the workpiece processing, the operator can adjust the position of the valve block 4 through the slider 21 to adapt to different workpieces for processing, and clamp them through the positioning mechanism 5 during the processing.

[0031] However, since the workpieces are of different models and batches, and are not only wide but also long, a single set of clamping pads 510 is insufficient for stable clamping. To address this issue, further research is needed. Figures 3-4 A secondary positioning block 58 is integrally provided on both sides of the main positioning block 54. The secondary positioning block 58 is hollow and forms a third chamber. The secondary positioning block 58 is L-shaped. The third chamber is connected to the first chamber. At the same time, a first inclined surface is provided on both sides of the first driving block 56, and a second driving block 57 is provided on both sides of the first driving block 56. The second driving block 57 has a second inclined surface that cooperates with the first inclined surface. In the initial state, the first inclined surface and the second inclined surface are in contact with each other. When the first driving block 56 is subjected to external force, it moves towards the position of the connecting rod 53. At this time, the first inclined surface exerts a squeezing effect on the second inclined surface, and the second driving block 57 is adapted to move in a direction away from each other.

[0032] A third clamping block 513 is fixedly installed on both sides of the second driving block 57. One part of the third clamping block 513 extends into the third chamber. It should be noted that the inner diameter of the third chamber is adapted to the inner diameter of the second driving block 57. Therefore, due to the restriction of the third chamber, the second clamping block 512 can only slide in a straight line and cannot deviate during the sliding process.

[0033] A second spring 511 is fixedly installed on the side of the third clamping block 513 away from the second driving block 57, and a second clamping block 512 is fixedly installed on the other side of the second spring 511. The main body of the second clamping block 512 is located in the third chamber, and a second clamping pad is fixedly installed at the end of the second clamping block 512 away from the second spring 511.

[0034] It should be noted that in this application, the second spring 511 has a high elastic strength. When the second spring 511 is subjected to compressive force, since the secondary positioning block 58 is "L" shaped, the second spring 511 will bend first and then compress. Secondly, the distance between the second driving block 57 and the inner walls on both sides of the first chamber is less than the length of the second clamping block 512 in the third chamber. Therefore, when one side of the second driving block 57 is in contact with the inner wall of the first chamber, the second clamping block 512 will not come out of the third chamber.

[0035] When the workpiece is clamped by the clamping pad 510, it will exert a squeezing effect on the first driving block 56. The first driving block 56 moves towards the position of the connecting rod 53. At this time, the first inclined plane exerts a squeezing effect on the second inclined plane, so the second driving block 57 moves away from each other. The movement of the second driving block 57 drives the third clamping block 513 to move away from each other. At the same time, the second spring 511 moves away from each other. Finally, the second clamping block 512 is disengaged from the third chamber, and the second clamping pad extends out to clamp the side of the workpiece. When the clamping pad 510 and the second clamping pads on both sides are on the same horizontal line, and when the side of the second driving block 57 is in contact with the side of the first chamber, the clamping force of the positioning mechanism 5 on the workpiece is the maximum.

[0036] In summary, during workpiece processing, the operator can adjust the position of the valve block 4 by cooperating with the slider 21 and the slide rail 2. After the position is adjusted, the workpiece on the valve block 4 can be clamped by the positioning mechanism 5, thereby making the workpiece more stable during processing.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
