Description

Technical Field

[0001] This utility model relates to the field of chain plate processing technology, specifically a fixture for chain plate processing. Background Technology

[0002] Chain plate processing fixtures are indispensable tools in the chain plate processing process. Through precise positioning and clamping mechanisms, they ensure that the chain plate remains stable and in the correct position during processing.

[0003] In existing chain plate machining processes, due to the presence of non-common holes in the chain plate's structure, multiple specialized fixtures are typically designed and used to accommodate machining requirements on different planes. This necessitates repeated clamping and positioning of the chain plate in multiple directions. Each clamping and positioning inevitably introduces some error, which accumulates gradually over multiple machining processes, potentially leading to a significant decrease in machining accuracy and affecting the overall performance and quality of the chain plate. When changing machining planes, the need to change fixtures and the accumulation of workpiece positioning errors make it difficult to ensure consistent surface finish and roughness of the chain plate, affecting its wear resistance and reliability in practical applications. Currently, clamping plate fixtures are commonly used for workpiece clamping and positioning. This tight-fitting clamping method is prone to loosening during use, resulting in significant wear and impacting machining quality and accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for chain plate processing, so as to solve the problem mentioned in the background art that the use of positioning pins or bolts for positioning, the time consumption for adjusting the position and aligning the positioning holes is large, which affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for chain plate processing, comprising:

[0006] The mounting base has a positioning plate at the top center, a side clamp plate (first) at the top front of the mounting base, and a side clamp plate (second) at the top rear of the mounting base.

[0007] A pre-positioning component is provided on the outside of the positioning plate. The positioning plate includes a limiting plate, and both the left and right ends of the limiting plate are provided with adjusting support plates. The top of the adjusting support plate is provided with a side limiting baffle. The pre-positioning component is used for pre-positioning support of the bottom of the workpiece.

[0008] A temporary storage component is located at the rear end of the second side clamping plate, and the temporary storage component includes a fixing plate. A temporary storage rack is connected to the rear end of the fixing plate. The temporary storage component is used to place the positioning pin.

[0009] Preferably, chain plate workpieces are provided on both the left and right sides of the top outer side of the positioning plate, and plug bolts penetrate the inner side of the positioning plate.

[0010] Preferably, a positioning slot is provided in the middle of the inner side of the mounting base plate, and clamping slots are provided at both the front and rear ends of the inner side of the mounting base plate.

[0011] Preferably, a fixed support plate is installed on the bottom of both the front and rear sides of the positioning plate, and a buffer connector assembly is connected to the top of the fixed support plate. A limit plate is connected to the top of the buffer connector assembly, and a pre-positioning groove is provided on the top wall of the limit plate.

[0012] Preferably, the positioning plate has a positioning hole on its inner side, and the side clamp has a docking hole on its inner side.

[0013] Preferably, the bottom of both ends of the positioning plate is provided with an adjustment support plate, and the inner side of the adjustment support plate is provided with a guide post.

[0014] Preferably, an adjusting screw is threadedly connected to the inner center of the adjusting support plate, and a side limiting baffle is connected to the top of the adjusting screw. A rotating shaft is connected between the adjusting screw and the side limiting baffle.

[0015] Preferably, the fixing plate is located at the rear end of the second side clamp, and the inner side of the fixing plate is connected with positioning bolts, and the rear end of the fixing plate is fixedly connected with six temporary storage racks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model patent's main clamping component consists of a positioning plate, a first side clamping plate, and a second side clamping plate. It achieves the effect of machining non-common holes in the chain plate workpiece in a single clamping operation, avoiding the error accumulation caused by multiple clamping and repositioning in traditional machining. This significantly improves machining accuracy, ensures the stability and accuracy of chain plate machining, and helps maintain the consistency of the chain plate's surface finish and roughness. During positioning, the inner bottom end of the chain plate workpiece contacts the limiting plate for support, while the outer bottom end is fitted with the adjusted side limiting baffle, achieving a pre-positioning effect. This effectively reduces the risk of workpiece wear and loosening during machining, thereby improving machining efficiency.

[0018] In addition, this fixture is equipped with a buffer connection assembly on the fixed support plate. This assembly can effectively absorb and disperse the vibration energy generated during equipment operation, adapt to different load conditions, and thus maintain machining accuracy.

[0019] To further improve installation efficiency, this utility model uses positioning bolts to temporarily store the plug-in bolts before and after positioning. The cross-section of the temporary storage rack is semi-circular and at the same height as the docking hole and positioning hole, which facilitates the direct insertion and positioning of subsequent plug-in bolts, thereby further improving installation efficiency.

[0025] 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.

[0026] 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.

[0027] like Figure 1-4 As shown, this application provides a fixture for chain plate processing, including: a mounting base plate 1, a positioning plate 2 provided at the top center of the mounting base plate 1, a side clamping plate 3 provided in front of the top of the mounting base plate 1, and a side clamping plate 4 provided behind the top of the mounting base plate 1.

[0028] Specifically, such as Figure 1 As shown, chain plate workpieces 5 are provided on both the left and right sides of the top outer side of the positioning plate 2, and a plug bolt 8 is passed through the inner side of the positioning plate 2. The plug bolt 8 is used to plug and position the chain plate workpieces 5.

[0029] Specifically, such as Figure 2As shown, a positioning slot 6 is provided in the middle of the inner side of the mounting base plate 1, and clamping plate slots 7 are provided at both the front and rear ends of the inner side of the mounting base plate 1. The clamping plate slots 7 are used for the insertion and positioning of the side clamping plate 3 and the side clamping plate 4, and the positioning slot 6 is used for the insertion and positioning of the positioning plate 2. The mounting base plate 1 can be adjusted as the size of the chain plate workpiece 5 is adjusted.

[0030] A pre-positioning component is provided on the outer side of the positioning plate 2. The positioning plate 2 includes a limiting plate 11, and both the left and right ends of the limiting plate 11 are provided with adjusting support plates 15. A side limiting baffle 18 is provided at the top of the adjusting support plate 15. The pre-positioning component is used for pre-positioning support of the bottom of the workpiece.

[0031] Specifically, such as Figure 3 As shown, fixed support plates 9 are installed on the bottom of both the front and rear sides of the positioning plate 2, and a buffer connector group 10 is connected to the top of the fixed support plate 9. A limit plate 11 is connected to the top of the buffer connector group 10, and a pre-positioning groove 12 is opened on the top wall of the limit plate 11. The fixed support plate 9 provides buffer support for the limit plate 11 through the buffer connector group 10. Then, the inner arc-shaped position of the chain plate workpiece 5 is placed in the pre-positioning groove 12 for initial pre-positioning.

[0032] Specifically, such as Figure 3 As shown, the inner side of the positioning plate 2 is provided with a positioning hole 14, and the inner side of the side clamping plate 3 is provided with a mating hole 13. The mating hole 13 and the positioning hole 14 are mated together to facilitate the connection and fastening of the plug bolts 8 between the base plate 1, the positioning plate 2 and the side clamping plate 3.

[0033] Specifically, such as Figure 4 As shown, the bottom of both ends of the positioning plate 2 is provided with an adjustment support plate 15, and the inner side of the adjustment support plate 15 is provided with a guide post 17. The guide post 17 is used to guide and limit the movement of the side limit baffle 18.

[0034] Specifically, such as Figure 4 As shown, an adjusting screw 16 is threadedly connected to the inner center of the adjusting support plate 15, and a side limiting baffle 18 is connected to the top of the adjusting screw 16. A rotating shaft is connected between the adjusting screw 16 and the side limiting baffle 18. The rotation of the adjusting screw 16 inside the adjusting support plate 15 will cause the adjusting screw 16 to move up and down, so that the side limiting baffle 18 will also move. The rotating shaft prevents the side limiting baffle 18 from rotating with the adjusting screw 16. The top wall of the side limiting baffle 18 is attached to the bottom wall of the chain plate workpiece 5 for support and limitation.

[0035] The rear end of the side clamp 4 is provided with a temporary storage component, which includes a fixing plate 19. The rear end of the fixing plate 19 is connected to a temporary storage rack 20. The temporary storage component is used to place the positioning pin.

[0036] Specifically, such as Figure 2 As shown, the fixing plate 19 is located at the rear end of the side clamping plate 2 4, and the inner side of the fixing plate 19 is connected with the positioning bolt 21. The rear end of the fixing plate 19 is fixedly connected with six temporary storage racks 20. After the plug bolt 8 and the positioning pin are unscrewed, they can be placed inside the temporary storage rack 20, so that when the next set of chain plate workpieces 5 are processed, they can be directly pushed in and screwed to complete the positioning. When not needed, the positioning bolt 21 can be loosened and removed.

[0037] In this embodiment: the chain plate workpiece 5 is placed in a fixture composed of positioning plate 2, side clamping plate 3 and side clamping plate 4, and the bottom end of the inner side contacts the limiting plate 11 for support, and the bottom end of the outer side is adapted to the adjusted side limiting baffle 18. The placement of the chain plate workpiece 5 achieves the effect of pre-positioning, reducing the adjustment time when the subsequent insertion bolt 8 is inserted and positioned. The positioning bolt 21 is set to temporarily store the insertion bolt 8 before and after positioning. The cross section of the temporary storage rack 20 is set to be semi-circular and at the same height as the docking hole 13 and the positioning hole 14, so that the subsequent insertion bolt 8 can be directly pushed into the insertion and positioning.

[0038] The specific steps of this solution are as follows: During use, firstly, select a suitable mounting base plate 1 according to the size of the chain plate workpiece 5. Then, insert the appropriate side clamping plates 1 and 2 on the clamping plate slots 7. Next, clamp the chain plate workpiece 5 on both outer ends of the positioning plate 2. At this time, the part of the chain plate workpiece 5 inside the side clamping plates 1 and 2 on the side clamping plates 3 and 4 rests on the pre-positioning slots 12 inside the limiting plate 11. The bottom buffer connecting assembly 10 provides buffer support. Then, the side limiting stop is controlled by rotating the adjusting screw 16 on the outside. The height of plate 18 allows the outer bottom wall of the chain plate workpiece 5 to fit against the top wall of the side limiting baffle 18 for outer support and limitation. The stability of the pre-positioning of the chain plate workpiece 5 is ensured by the support at two points. Then, the plug bolt 8 is passed through the second side clamping plate 4, the chain plate workpiece 5, the positioning plate 2, and the first side clamping plate 3 in sequence and tightened to position and clamp the chain plate workpiece 5. When replacing the chain plate workpiece 5, the unscrewed plug bolt 8 and positioning pin can be placed on the temporary storage rack 20 for easy direct plugging and tightening later.
