Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat cover punching and positioning technology, and in particular to a seat cover punching and positioning mechanism. Background Technology
[0002] In the production of seat covers, punching is a common process requirement, such as for processing ventilation holes, decorative holes, or mounting and positioning holes.
[0003] Existing traditional punching equipment typically uses simple mechanical clamping or manual positioning methods, which makes it difficult to guarantee the accuracy of the punching position. This is especially true when processing flexible materials (such as leather and fabrics), where the material is prone to displacement or deformation, leading to hole position deviations and affecting product quality. Existing equipment often uses a single clamping method (such as mechanical pressure plates or vacuum adsorption), but flexible materials are prone to local deformation or slippage during the punching process due to the punching force, resulting in uneven punching edges or hole position deviations. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of insufficient positioning accuracy and poor fixing stability in the existing technology by providing a seat cover punching positioning mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seat cover punching and positioning mechanism, comprising a punching device, a groove formed on the outer surface of the punching device, a moving block sleeved on the inner wall of the groove, a locking hole formed on the inner wall of the groove, a sliding groove formed on the outer surface of the moving block, a pressing block fixedly connected to one side of the moving block, a moving plate fixedly connected to the outer surface of the pressing block, a locking block fixedly connected to the outer surface of the moving plate, a spring fixedly connected to the outer surface of the locking block, a limit rod fixedly connected to one end of the locking block, a sliding rod sleeved on the inner wall of the moving plate, a knob provided on one side of the moving block, a lead screw fixedly connected to one end of the knob, a pressure plate sleeved on the outer surface of the lead screw, and a bearing fixedly connected to one end of the lead screw.
[0006] In a preferred embodiment, a vacuum plate is fixedly connected to the outer surface of the punching equipment, an extraction tube is fixedly connected to one side of the vacuum plate, and a vacuum pump is fixedly connected to one end of the extraction tube.
[0007] In a preferred embodiment, the outer surface of the vacuum pump is fixedly connected to the outer surface of the punching device, the extraction tube is placed inside the punching device, and the outer surface of the extraction tube is engaged with the inner wall of the punching device.
[0008] In a preferred embodiment, the inner wall of the chute is slidably connected to the outer surface of the moving block, and the inner wall of the pressure plate is threadedly connected to the outer surface of the lead screw.
[0009] In a preferred embodiment, the inner wall of the sliding groove is provided with a groove, and the outer surface of the limiting rod is slidably connected to the inner wall of the groove.
[0010] In a preferred embodiment, one end of the spring is fixedly connected to the inner wall of the sliding groove, and the outer surface of the locking block is slidably connected to the inner wall of the sliding groove.
[0011] In a preferred embodiment, the outer surface of the movable plate is provided with a through hole, and the outer surface of the slide rod is slidably connected to the inner wall of the through hole.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] This invention utilizes a punching device to punch holes in seat covers. A sliding connection between a groove and a movable block ensures the movable block can move normally, thereby moving other components to securely hold the seat cover in place during punching. Once the movable block reaches the desired position, releasing the pressing block allows the spring to return, causing the locking block to engage with the locking hole, thus fixing the movable block in place. Then, rotating a knob rotates a lead screw within a bearing. The lead screw is threadedly connected to a pressure plate, causing the pressure plate to move and adhere to the surface of the seat cover, thus securing and limiting the seat cover and ensuring the punching process proceeds smoothly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a seat cover punching and positioning mechanism, including a punching device 1, a groove 2 on the outer surface of the punching device 1, a moving block 3 sleeved on the inner wall of the groove 2, a locking hole 4 on the inner wall of the groove 2, a sliding groove 5 on the outer surface of the moving block 3, a pressing block 6 fixedly connected to one side of the moving block 3, a moving plate 7 fixedly connected to the outer surface of the pressing block 6, a locking block 9 fixedly connected to the outer surface of the moving plate 7, a spring 11 fixedly connected to the outer surface of the locking block 9, a limit rod 10 fixedly connected to one end of the locking block 9, a sliding rod 8 sleeved on the inner wall of the moving plate 7, a knob 12 on one side of the moving block 3, a lead screw 13 fixedly connected to one end of the knob 12, a pressure plate 14 sleeved on the outer surface of the lead screw 13, and a bearing 15 fixedly connected to one end of the lead screw 13.
[0022] In this embodiment, the seat cover is punched using a punching device 1. A sliding groove 2 is slidably connected to a movable block 3, ensuring the movable block 3 can move normally. This movable block 3 then moves other components, thus securing the seat cover and preventing it from shifting during punching. When the movable block 3 is in motion, the pressing block 6 causes the movable plate 7 to slide along the sliding rod 8, thereby moving the locking block 9 into the sliding groove 5 and simultaneously moving the limiting rod 10. The movement of the locking block 9 compresses the spring 11. After the moving block 3 is moved to the appropriate position, the pressing block 6 is released, and the spring 11 rebounds, causing the locking block 9 to rebound, thereby engaging the locking block 9 with the locking hole 4 to fix the moving block 3 and ensure that the moving block 3 will not move. Then, by rotating the knob 12, the lead screw 13 is driven to rotate inside the bearing 15. The lead screw 13 is threadedly connected to the pressure plate 14, so while the lead screw 13 is rotating, it drives the pressure plate 14 to move, thereby making the pressure plate 14 fit against the surface of the seat cover, thus fixing and limiting the seat cover and ensuring that the punching work is carried out normally. Example 2
[0023] like Figures 1-4As shown, a vacuum plate 18 is fixedly connected to the outer surface of the punching equipment 1. An extraction tube 17 is fixedly connected to one side of the vacuum plate 18. A vacuum pump 16 is fixedly connected to one end of the extraction tube 17. The outer surface of the vacuum pump 16 is fixedly connected to the outer surface of the punching equipment 1. The extraction tube 17 is placed inside the punching equipment 1, and the outer surface of the extraction tube 17 is engaged with the inner wall of the punching equipment 1.
[0024] In this embodiment, when punching, the seat cover is first placed on the outer surface of the vacuum plate 18, and then the air between the seat cover and the vacuum plate 18 is extracted by the vacuum pump 16 and the extraction is carried out by the extraction tube 17, so that a negative pressure is formed between the seat cover and the vacuum plate 18, thereby fixing the seat cover.
[0025] Working principle:
[0026] like Figures 1-4 As shown, in this utility model, when punching the seat cover using the punching equipment 1, the worker first places the seat cover on the surface of the vacuum plate 18. Then, the vacuum pump 16 drives the extraction tube 17 to extract the air between the seat cover and the vacuum plate 18, creating a negative pressure between the seat cover and the vacuum plate 18, thereby fixing the seat cover. Then, when the moving block 3 moves inside the slide groove 2, the pressing block 6 drives the moving plate 7 to slide along the slide rod 8, thereby driving the locking block 9 to move into the slide groove 5, and at the same time driving the limiting rod 10 to move. The movement compresses the spring 11. After the moving block 3 moves to the appropriate position, the pressing block 6 is released, and the spring 11 rebounds, causing the locking block 9 to rebound, thereby engaging the locking block 9 with the locking hole 4 to fix the moving block 3 and ensure that the moving block 3 will not move. Then, by rotating the knob 12, the lead screw 13 is driven to rotate inside the bearing 15. The lead screw 13 is threadedly connected to the pressure plate 14, so while the lead screw 13 is rotating, it drives the pressure plate 14 to move, thereby making the pressure plate 14 fit against the surface of the seat cover, thus fixing and limiting the seat cover and ensuring that the punching work is carried out normally.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
