Description
Technical Field
[0001] This utility model belongs to the field of trimmer technology, specifically a pneumatic gripper mechanism for trimmers. Background Technology
[0002] In modern industrial production, trimming machines are widely used in the processing of various products, such as edge trimming and burr removal of rubber and plastic products. The efficient operation of trimming machines relies on their key actuators—the gripper mechanism. Pneumatic gripper mechanisms, with their advantages of fast response, ease of operation, and relatively low cost, have been widely used in the trimming machine field.
[0003] Existing pneumatic gripper mechanisms also have shortcomings in terms of stability and reliability. During long-term continuous operation, due to factors such as air pressure fluctuations and seal wear, malfunctions such as gripper loosening and abnormal operation are prone to occur, which not only reduces production efficiency but also increases equipment maintenance costs and downtime.
[0004] Therefore, this utility model provides a pneumatic gripper mechanism for a trimmer. Utility Model Content
[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a pneumatic gripper mechanism for a trimming machine is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A pneumatic gripper mechanism for a trimmer, comprising a protective plate; a fixing ring is fixedly installed on one side of the inner wall of the protective plate; a pneumatic component is provided on the inner wall of the protective plate; a clamping component is provided on the side of the protective plate near the fixing ring; a fixing component is provided on the inner wall of the protective plate; an anti-slip and detachment component is provided on the side of the protective plate near the clamping component; and a limiting component is provided on the inner wall of the protective plate; the fixing component includes a fixing plate and a fixing block; several sets of fixing plates are provided, and these sets are fixedly installed in a ring on the inner wall of the protective plate; the side of the fixing plate away from the protective plate is fixedly installed with the fixing block; the cooperation of the fixing plate and the fixing block can reinforce the pneumatic component, enabling it to be used stably and safely, while also providing a stable sliding space for the limiting slide bar.
[0007] Preferably, the pneumatic assembly includes a cylinder, a cross-shaped push plate, and a linkage plate. The cylinder is fixedly installed on the inner wall of the fixed block, and the output end of the cylinder is fixedly installed with the cross-shaped push plate. Several sets of linkage plates are provided, and the several sets of linkage plates are installed in a ring rotation on both sides of the cross-shaped push plate. In this scheme, the cooperation between the cylinder and the cross-shaped push plate can realize the function of simultaneously pushing four sets of clamping frames, so that the clamping frames can have strong precision and clamping force. The linkage plate can realize the connection between the cross-shaped push plate and the clamping frames, so that the cylinder can control the clamping of the clamping frames by extension and retraction.
[0008] Preferably, the clamping assembly includes a fixed shaft block and a clamping frame. The fixed shaft block is provided in four sets, and the four sets of fixed shaft blocks are fixedly installed in a ring on the side of the protective plate near the fixed ring. The inner wall of the fixed shaft block away from the protective plate is rotatably installed with the clamping frame. The linkage plate is rotatably installed with the clamping frame on the side away from the cross push plate. In this solution, the cooperation between the fixed shaft block and the clamping frame can improve the clamping stability through the multi-set linkage design, effectively preventing the clamped object from falling off and causing a deterioration in trimming quality.
[0009] Preferably, the anti-slip detachment component includes an arc-shaped plate and an anti-slip strip. The arc-shaped plate is fixedly installed at the end of the clamping frame away from the fixed shaft block, and the inner side of the arc-shaped plate is fixedly installed with the anti-slip strip. In this solution, the arc-shaped plate can clamp the item, and its own curvature can better fit some round items. The anti-slip strip can play an anti-slip role, further ensuring that the item will not fall off during trimming.
[0010] Preferably, the limiting component includes limiting slide rods and limiting holes. The limiting holes are formed on the surface of the fixed plate. Four sets of limiting slide rods are provided, and the four sets of limiting slide rods are fixedly installed in a ring on the side of the cross push plate near the cylinder. The limiting slide rods are slidably connected to the fixed ring through the limiting holes. In this design, the limiting holes enable the limiting slide rods to slide more stably and smoothly. The limiting slide rods can provide support for the cross push plate when it extends and retracts, reducing the support burden on the cylinder.
[0011] Preferably, the surfaces of the arc-shaped plate, the clamping frame, and the protective plate are all coated with anti-rust paint. In this solution, the application of anti-rust paint can effectively prevent the machinery from rusting after long-term use, thereby improving the service life of the machinery and playing a protective role.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The pneumatic gripper mechanism for a trimmer described in this utility model, through the setting of a fixed plate and a fixed block, enables the pneumatic components to be reinforced and used stably, ensuring safe use, while also providing a stable sliding space for the limit slide bar.
[0014] 2.

[0025] Specific implementation examples are given below.
[0026] like Figures 1 to 6 As shown in the embodiment of this utility model, a pneumatic gripper mechanism for a trimmer includes a protective plate 1; a fixing ring 2 is fixedly installed on one side of the inner wall of the protective plate 1; a pneumatic component 4 is provided on the inner wall of the protective plate 1; a clamping component 5 is provided on the side of the protective plate 1 near the fixing ring 2; a fixing component 6 is provided on the inner wall of the protective plate 1; an anti-slip and detachment component 7 is provided on the side of the protective plate 1 near the clamping component 5; and a limit component 8 is provided on the inner wall of the protective plate 1; the fixing component 6 includes a fixing plate 61 and a fixing block 62; several sets of fixing plates 61 are provided, and several sets of fixing plates 61 are fixedly installed in a ring on the inner wall of the protective plate 1; the side of the fixing plate 61 away from the protective plate 1 is fixedly installed with the fixing block 62; the pneumatic component 4 includes a cylinder 41, a cross pusher plate 42, and a linkage plate 43; the cylinder 41 is fixedly installed on the inner wall of the fixing block 62, and the output end of the cylinder 41 is fixedly installed with the cross pusher plate 42; several sets of linkage plates 43 are provided, and several sets of linkage plates 43 are rotatably installed in a ring on the cross pusher plate. On both sides of 42, the clamping assembly 5 includes a fixed shaft block 51 and a clamping frame 52. Four sets of fixed shaft blocks 51 are provided, and the four sets of fixed shaft blocks 51 are fixedly installed in a ring on the side of the protective plate 1 near the fixed ring 2. The inner wall of the fixed shaft block 51 away from the protective plate 1 is rotatably installed with the clamping frame 52. The linkage plate 43 is rotatably installed with the clamping frame 52 on the side away from the cross push plate 42. The anti-slip assembly 7 includes an arc-shaped plate 71 and an anti-slip rubber strip 72. The arc-shaped plate 71 is fixedly installed on the clamping frame 52 away from the fixed ring 2. One end of the fixed shaft block 51, the inner side of the arc plate 71 and the anti-slip rubber strip 72 are fixedly installed. The limiting component 8 includes a limiting slide rod 81 and a limiting hole 82. The limiting hole 82 is opened on the surface of the fixed plate 61. There are four sets of limiting slide rods 81. The four sets of limiting slide rods 81 are fixedly installed in a ring on the side of the cross push plate 42 near the cylinder 41. The limiting slide rods 81 are slidably connected to the fixed ring 2 through the opening of the limiting hole 82. The surfaces of the arc plate 71, the clamping frame 52 and the protective plate 1 are all coated with anti-rust paint.
[0027] like Figures 1 to 6As shown, the cooperation of the fixed plate 61 and the fixed block 62 can reinforce the pneumatic component 4, ensuring its stable and safe operation. It also provides a stable sliding space for the limit slide bar 81. The cooperation of the cylinder 41 and the cross push plate 42 enables the simultaneous pushing of four sets of clamping frames 52, giving the clamping frames 52 high precision and clamping force. The linkage plate 43 connects the cross push plate 42 and the clamping frames 52, allowing the cylinder 41 to control the clamping of the clamping frames 52 through extension and retraction. The cooperation of the fixed shaft block 51 and the clamping frames 52 enables multiple sets of linkage... The design enhances clamping stability, effectively preventing items from slipping off and compromising trimming quality. The curved plate 71 grips the items and its curvature better accommodates round objects. The anti-slip strip 72 provides anti-slip protection, further ensuring items don't slip during trimming. The limiting hole 82 allows the limiting slide rod 81 to slide more stably and smoothly, providing support for the cross push plate 42 during extension and retraction, reducing the load on the cylinder 41. The anti-rust coating effectively prevents rust from forming during prolonged use, extending the machine's lifespan and providing protection.
[0028] Working principle: During operation, first install the protective plate 1 into the usage position, and then it can be used. When clamping is required, first start the cylinder 41 to push the cross push plate 42 to one side. When the cross push plate 42 moves, the limit slide rod 81 will slide to ensure that the movement of the cross push plate 42 is more stable. At the same time, the movement of the cross push plate 42 will push the linkage plate 43 to move. The movement of the linkage plate 43 will rotate the clamping frame 52 outward around the fixed shaft block 51. When the four clamping frames 52 rotate at the same time, the hooks open and the items to be clamped are placed inside the arc plate 71. Then start the cylinder 41 to pull the cross push plate 42 to retract. The retraction of the cross push plate 42 will pull the linkage plate 43 to move. The movement of the linkage plate 43 will pull the clamping frame 52 to rotate. When the clamping frame 52 rotates, it will clamp the items through the arc plate 71. The four clamping frames 52 in this utility model can enhance the clamping effect and effectively prevent the items from falling off during the clamping process.
