Description

Technical Field

[0001] This utility model relates to the field of automotive seat slide rail processing, and in particular to an automotive seat slide rail steel ball stop point pressing device. Background Technology

[0002] Before assembling steel balls, steel ball stops need to be pressed into the car seat slide rail. In existing technology, the left and right presser feet and slide rail seats are usually fixed. To achieve better clamping and support, the gap between the left and right presser feet and the seat slide rail is usually small. The shortcomings are that, due to tolerance fluctuations, it is difficult to insert the seat slide rail, and after pressing out the stops, the seat slide rail is prone to getting stuck on the left and right presser feet, making it difficult to unload. To solve these problems, the presser feet and slide rail seats need to be frequently re-grinded, which increases the gap between the presser feet and the seat slide rail, causing greater deformation of the seat slide rail after pressing out the stops. In addition, the stop head is also prone to sticking to the seat slide rail, making it difficult to unload and affecting the efficiency of the production line. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by developing a steel ball stop-point pressing device for automotive seat slide rails. The technical solution adopted by this utility model is as follows: a steel ball stop-point pressing device for automotive seat slide rails, characterized by comprising a frame 1, a base 2, and a slide rail positioning device 20; a hydraulic press 3 fixedly connected to the upper part of the frame 1; an upper pressure plate 4 fixedly connected to the piston rod of the hydraulic press 3; a first guide post 5, a second guide post 6, a left pressure block 7, and a right pressure block 8 respectively fixedly connected to the lower part of the upper pressure plate 4; a left pressure foot 9 slidably connected to the first guide post 5; a right pressure foot 10 slidably connected to the second guide post 6; a first spring 11 sleeved on the first guide post 5; a second spring 12 sleeved on the second guide post 6; a left inclined wedge seat 15, a right inclined wedge seat 16, and a slide rail seat 17 respectively fixedly mounted on the base 2; the left inclined wedge seat 15 and the right inclined wedge seat 16 respectively positioned on both sides of the slide rail seat 17; a left inclined wedge 13 slidably connected to the left inclined wedge seat 15; and a right inclined wedge... 14 is slidably connected to the right inclined wedge seat 16; the inclined surface at the lower end of the left pressure block 7 is in contact with the left inclined surface of the left inclined wedge 13; the inclined surface at the lower end of the right pressure block 8 is in contact with the right inclined surface of the right inclined wedge 14; the slide rail seat 17 has a left pressure head guide hole 24 and a right pressure head guide hole 25 respectively on both sides; the left pressure head 18 is inserted into the left pressure head guide hole 24; the right pressure head 19 is inserted into the right pressure head guide hole 25; a third spring 26 is sleeved on the upper end of the left pressure head 18; a fourth spring 27 is sleeved on the upper end of the right pressure head 19; the slide rail positioning device 20 includes a bracket 21, a third guide post 22 and a slide rail positioning block 23; the bracket 21 is fixedly mounted on the base 2; the third guide post 22 passes through the slide rail positioning block 23; the slide rail positioning block 23 is slidably connected to the bracket 21; the locking screw 31 can lock the slide rail positioning block 23.

[0004] The advantages of this utility model are as follows: 1. By using a hydraulic press to press the left and right pressure feet to tighten the seat slide rail, the jamming of the seat slide rail caused by using a fixed pressure foot is avoided, and there is no need to frequently grind the pressure feet or slide rail seats; 2. By using the left and right pressure blocks to squeeze the left and right inclined wedges, the left and right pressure heads are forced to press out blocking points on both sides of the seat slide rail. After the pressing process is completed, when the left and right pressure feet are still pressing the seat slide rail, the elastic force of the third and fourth springs forces the left and right pressure heads to detach from the seat slide rail, effectively preventing the pressure heads from sticking to the seat slide rail, making the unloading process smooth and improving the efficiency of the production line.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figures 1 to 3As shown, the present invention provides a steel ball stop pressing device for automotive seat slide rails, comprising: a frame 1, a base 2, and a slide rail positioning device 20; a hydraulic press 3 fixedly connected to the upper part of the frame 1; an upper pressure plate 4 fixedly connected to the piston rod of the hydraulic press 3; a first guide post 5, a second guide post 6, a left pressure block 7, and a right pressure block 8 respectively fixedly connected to the lower part of the upper pressure plate 4; a left pressure foot 9 slidably connected to the first guide post 5; a right pressure foot 10 slidably connected to the second guide post 6; a first spring 11 sleeved on the first guide post 5; a second spring 12 sleeved on the second guide post 6; a left inclined wedge seat 15, a right inclined wedge seat 16, and a slide rail seat 17 respectively fixedly mounted on the base 2; the left inclined wedge seat 15 and the right inclined wedge seat 16 respectively mounted on both sides of the slide rail seat 17; a left inclined wedge 13 slidably connected to the left inclined wedge seat 15; a right inclined wedge 14 slidably connected to the left inclined wedge seat 15; and a right inclined wedge 14 slidably connected to the right inclined wedge seat 16. The right inclined wedge seat 16 is slidably connected; the inclined surface at the lower end of the left pressure block 7 is in contact with the left inclined surface of the left inclined wedge 13; the inclined surface at the lower end of the right pressure block 8 is in contact with the right inclined surface of the right inclined wedge 14; the left pressure head guide hole 24 and the right pressure head guide hole 25 are respectively opened on both sides of the slide rail seat 17; the left pressure head 18 is inserted into the left pressure head guide hole 24; the right pressure head 19 is inserted into the right pressure head guide hole 25; a third spring 26 is sleeved on the upper end of the left pressure head 18; a fourth spring 27 is sleeved on the upper end of the right pressure head 19; the slide rail positioning device 20 includes a bracket 21, a third guide post 22 and a slide rail positioning block 23; the bracket 21 is fixedly mounted on the base 2; the third guide post 22 passes through the slide rail positioning block 23; the slide rail positioning block 23 is slidably connected to the bracket 21; the locking screw 31 can lock the slide rail positioning block 23.

[0018] In specific operations, such as Figure 4 and Figure 5 As shown, the worker places the seat slide rail 28 with the opening facing down onto the slide rail seat 17, and... Figure 5 In the middle, push the seat slide rail 28 to the left side of the diagram so that its left end is flush with the slide rail positioning block 23, which has completed the positioning process; then as follows Figure 6 As shown, the worker operates the piston rod of the hydraulic press 3 to press down, causing the upper pressure plate 4 to move downwards. The upper pressure plate 4 first drives the left pressure foot 9 and the right pressure foot 10 to press into the flanges on both sides of the seat slide rail 28; as shown Figure 7 and Figure 8As shown, the piston rod of the hydraulic press 3 continues to press down, and the upper pressure plate 4 also continues to move downward. The left pressure block 7 and the right pressure block 8 fixed at the lower end of the upper pressure plate 4 respectively force the left wedge 13 to move to the right along the left wedge seat 15 and the right wedge 14 to move to the left along the right wedge seat 16. The left wedge 13 forces the left pressure head 18 to press the seat slide rail 28 to the upper right, and the right wedge 14 forces the right pressure head 19 to press the seat slide rail 28 to the upper left, thus completing the steel ball stop pressing process of the seat slide rail. Since the first spring 11 and the second spring 12 are sleeved on the first guide post 5 and the second guide post 6, it is ensured that during the continuous downward pressing of the upper pressure plate, the left pressure foot 9 and the right pressure foot 10 can press the seat slide rail 28 tightly without excessive pressure that could damage it or the slide rail seat 17 itself.

[0019] After the steel ball pressing process is completed, the worker operates the piston rod of the hydraulic press 3 to move upward. The upper pressure plate 4 first lifts the left pressure block 7 and the right pressure block 8. At this time, if... Figure 9 As shown, the elastic force of the third spring 26 and the fourth spring 27 forces the left pressure head 18 and the right pressure head 19 to disengage from the seat slide rail 28. At this time, since the left pressure foot 9 and the right pressure foot 10 are still pressed on the flange of the seat slide rail 28, the pressure feet are effectively prevented from sticking to the seat slide rail. As the piston rod of the hydraulic press 3 continues to move upward, the left pressure foot 9 and the right pressure foot 10 are also lifted, and the worker will... Figure 10 The seat rail 28 shown can be removed.

[0020] The position of the slide rail positioning block 23 in the slide rail positioning device 20 can be adjusted according to the processing dimensions. After adjustment, tighten the locking screw 31 to lock the slide rail positioning block 23.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of the present utility model.
