Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly relates to a welding device for processing automobile seat slides. Background Art

[0002] In order to facilitate the installation of automobile seat slides, it is often necessary to weld fasteners to various parts of the seat slides. The traditional welding method is completed manually. However, during the welding process, the seat slide may shift, resulting in the shift of the welding position and affecting the welding effect. Even to ensure a good welding effect, it is necessary to adjust the position of the seat slide multiple times, which is cumbersome to operate and has low work efficiency.

[0003] In order to overcome the problems existing in the traditional welding method, many positioning devices that can position the seat slide have emerged on the market. For example, a Chinese patent with the publication number CN218983648U discloses a welding device for automobile seat slides, including: a frame, used as a framework, which includes a working layer and a placement layer; a welding table, arranged on the working layer for placing welding objects; a limit adjustment mechanism, arranged on the working layer and between the welding table and the side wall of the frame for restricting the position of the welding table; an azimuth adjustment mechanism, arranged on the top of the frame; a welding torch assembly, connected to the azimuth adjustment mechanism through a cylinder, capable of changing its position under the adjustment of the azimuth adjustment mechanism and capable of moving up and down under the adjustment of the cylinder; wherein, the working layer has a chute and a through hole; the welding table is connected to the working layer through the chute and can move along the chute; there are 2 welding tables and limit adjustment mechanisms, and they are symmetrically arranged with respect to the through hole of the working layer; a collection box is arranged on the placement layer, and the collection box is directly below the through hole; a pressing mechanism is arranged on the upper end surface of the welding table, and the pressing mechanism includes a clamping plate, a connecting rod, and a torsion spring; the connecting rod is arranged on the upper end surface of the welding table; the clamping plate is hinged to the connecting rod; both the clamping plate and the upper end surface of the welding table have spring slots; the torsion spring is adaptively connected to the clamping plate, the connecting rod, and the upper end surface of the welding table through the spring slots; this welding device can press and position the seat slide, ensuring that the seat slide will not shift during welding, thereby ensuring the welding effect; moreover, there is no need to adjust the position of the seat slide multiple times, ensuring the work efficiency.

[0004] The above welding device has the following problems during actual use: Before positioning the seat slide, press one end of the clamping plate downward to make the other end of the clamping plate tilt up, place the seat slide between the welding table and the clamping plate, and then release the pressed end of the clamping plate to clamp and position the seat slide; however, before positioning the seat slide, it is necessary to keep pressing both sides of the clamping plate simultaneously to make both sides of the clamping plate tilt up, and then the seat slide can be placed in the position to be positioned, which is very inconvenient to operate; moreover, since one end of the clamping plate in contact with the seat slide is arc-shaped, the contact surface between the two is small, resulting in a poor positioning effect on the seat slide. Summary of the Invention

[0005] The present invention aims to provide a welding device for processing automobile seat slides, so as to solve the problem that the existing device has inconvenient operation in the positioning method of seat slides.

[0006] To achieve the above object, the present invention adopts the following technical scheme: A welding device for processing automobile seat slides includes a base and a welding mechanism. There are bosses and placing tables located on both sides of the boss on the base; there is a chamber inside the boss, and both sides of the chamber are rotatably connected with rotating shafts, and the rotation directions of the two rotating shafts are opposite; there are wall blocks on the rotating shafts, and arc-shaped blocks are connected to the wall blocks; there is an elastic layer at the bottom of the arc-shaped block, and the thickness of the elastic layer gradually increases from the free end of the arc-shaped block to the other end of the arc-shaped block; there are side grooves on both sides of the boss, and the side grooves communicate with the chamber, and both the arc-shaped block and the elastic layer can rotate in the side grooves; it also includes a driving mechanism for simultaneously driving the two rotating shafts to rotate.

[0007] The principle and advantages of this solution are: 1. In this solution, the seat slide is placed on the placing table. The driving mechanism simultaneously drives the two rotating shafts to rotate. The rotating shafts drive the arc-shaped block and the elastic layer to rotate through the wall blocks, so that the elastic layer abuts against the seat slide, thereby realizing the pressing and positioning of the seat slide. Compared with the prior art, in this solution, the placement and positioning of the seat slide are carried out separately and do not interfere with each other, and the operation is more convenient.

[0008] 2. This solution uses the elastic layer to press and position the seat slide. Since the elastic layer has a certain ductility, the contact between the elastic layer and the seat slide is more sufficient, thereby being able to strengthen the positioning effect of the seat slide.

[0009] 3. In this solution, since the thickness of the elastic layer gradually increases from the free end of the arc-shaped block to the other end of the arc-shaped block, therefore, according to the size of the seat slide, the rotation amplitude of the arc-shaped block and the elastic layer can change accordingly, thereby being able to be applicable to the positioning of seat slides of different sizes.

[0010] 4. In this solution, seat slides can be placed on both placing tables on both sides, that is, the pressing and positioning of two seats can be carried out simultaneously, and the working efficiency is higher.

[0011] Further, the driving mechanism includes racks located on both sides inside the chamber, gears coaxially connected to the rotating shafts, and a driving part for simultaneously driving the two racks to move vertically back and forth. The racks are engaged with the gears.

[0012] Through the above settings, the driving part can simultaneously drive the two racks to move vertically, so that the racks are engaged with the gears to drive the rotating shafts to rotate.

[0013] Further, the driving part includes a driving shaft, a fixing plate fixedly connected to the inner wall of the chamber, and a driving member for driving the driving shaft to rotate. A cylindrical cam is coaxially connected to the driving shaft. A curve groove is provided on the cylindrical cam. A guiding block is slidably connected in the curve groove. A lifting block is provided at one end of the guiding block away from the curve groove. A side block is provided between the rack and the lifting block. A bottom block is provided on the side block. The bottom block is vertically slidably connected to the fixing plate.

[0014] With the above arrangement, the driving member drives the driving shaft to rotate, the driving shaft drives the cylindrical cam to rotate, the cylindrical cam drives the guiding block to move upward through the curve groove, and the guiding block drives the two racks to move upward simultaneously through the side blocks and the bottom block on both sides.

[0015] Further, a transverse plate is provided in the side groove. The transverse plate can move horizontally in the side groove. The thickness of the transverse plate is less than the depth of the arc groove. An arc groove is provided at the top of the arc block. The two sides of the transverse plate along the length direction are in frictional contact with the two sides of the arc groove. A linkage mechanism is further included which drives the two transverse plates to move horizontally simultaneously as the driving shaft rotates.

[0016] With the above arrangement, during the rotation of the driving shaft, the two transverse plates are driven to move horizontally simultaneously through the linkage mechanism. Therefore, during the rotation of the driving shaft, the arc block and the elastic layer rotate, and at the same time the transverse plates move horizontally, so that the transverse plates move horizontally in the arc groove. The arc groove at the top of the arc block is in frictional contact with the two sides of the transverse plate along the length direction, thereby being able to guide the movement of the arc block and the elastic layer. And, when the elastic layer presses against the seat slide rail, it will deform. If there is no restriction of the arc block by the transverse plate through the arc groove, the arc block and the elastic layer may shake or shift. Therefore, the frictional contact between the transverse plate and the arc groove can prevent the arc block and the elastic layer from moving and shifting, ensuring the pressing and positioning of the seat slide rail.

[0017] Further, a through hole is vertically provided on the transverse plate. A movable block is vertically slidably connected in the through hole. A first spring is provided between the movable block and the transverse plate. The bottom of the arc groove is located on the movement track of the movable block. A wall shaft is rotatably connected to the wall block. A torsion spring is provided between the wall shaft and the wall block. The arc block is fixedly connected to the wall shaft. A baffle is provided on the wall block. The baffle abuts against the arc block. A pressing mechanism is further included for simultaneously pressing the two movable blocks to move vertically.

[0018] With the above arrangement, during the horizontal movement of the transverse plate, the transverse plate drives the movable block to move synchronously, so that the movable block is on the side away from the boss in the arc groove, that is, the left movable block is at a position close to the left side in the left arc groove, and the right movable block is at a position close to the right side in the right arc groove.

[0019] During the rotation of the drive shaft, the squeezing mechanism drives two movable blocks to move downward simultaneously. The movable blocks squeeze the bottom of the arc-shaped groove to drive the arc-shaped block and the elastic layer to move downward, causing the torsion spring to deform, making the elastic layer deform more, and thus enabling the elastic layer to contact the seat slide rail more fully, that is, strengthening the pressing and positioning effect on the seat slide rail.

[0020] Furthermore, the linkage mechanism includes an elliptical block coaxially connected to the drive shaft, a vertical plate fixedly connected to the inner wall of the side groove. The transverse plate is slidably connected to the vertical plate horizontally, and a second spring is provided between the transverse plate and the vertical plate. The transverse plate abuts against the elliptical block.

[0021] With the above arrangement, during the rotation of the drive shaft, the drive shaft drives the elliptical block to rotate, causing the two short-axis ends of the elliptical block to gradually move away from the two transverse plates, while the two long-axis ends of the elliptical block gradually approach the two transverse plates. Therefore, the rotation of the elliptical block can be used to simultaneously squeeze the two transverse plates to move horizontally, causing the two transverse plates to move apart.

[0022] Furthermore, the squeezing mechanism linkage shaft includes linkage grooves opened on both sides of the convex platform, linkage blocks fixedly connected to the movable blocks, and a worm coaxially connected to the drive shaft. An auxiliary block is provided in the linkage groove. The linkage shaft passes through the chamber and is rotatably connected to the auxiliary block. A worm gear meshing with the worm and cam bodies located at both ends of the linkage shaft are coaxially connected to the linkage shaft. The cam bodies abut against the linkage blocks.

[0023] With the above arrangement, during the rotation of the drive shaft, the drive shaft drives the worm to rotate. The worm meshes with the worm gear to drive the linkage shaft to rotate. The linkage shaft drives the two cam bodies to rotate synchronously, causing the convex portions of the cam bodies to gradually approach the linkage blocks. Therefore, the rotation of the cam bodies can be used to squeeze the linkage blocks to drive the movable blocks to move downward.

[0024] Furthermore, the welding mechanism includes a welding assembly and a top seat fixedly connected to the base. A first cylinder is provided on the top seat. A top block is provided on the output shaft of the first cylinder. The top block is slidably connected to the top seat horizontally; a second cylinder is provided at the bottom of the top block. The output shaft of the second cylinder is fixedly connected to the welding assembly.

[0025] With the above arrangement, after the positioning of the seat slide rail is completed, the first cylinder is started. The output shaft of the first cylinder drives the top block and the welding assembly to move horizontally, and the output shaft of the second cylinder drives the welding assembly to move vertically. In this way, the position of the welding assembly can be adjusted according to the welding position requirements to complete the welding work. Brief Description of the Drawings

[0032] A transverse plate 40 is arranged in the side groove 26. The transverse plate 40 can move transversely in the side groove 26, and the thickness of the transverse plate 40 is less than the depth of the arc groove 41. An arc groove 41 is formed at the top of the arc block 22, and both sides of the transverse plate 40 along the length direction are in frictional contact with both sides of the arc groove 41. It further includes a linkage mechanism that drives the two transverse plates 40 to move transversely while rotating with the drive shaft. The linkage mechanism includes an elliptical block 42 coaxially connected to the drive shaft and a vertical plate 43 fixedly connected to the inner wall of the side groove 26. The transverse plate 40 is slidably connected to the vertical plate 43 transversely, and a second spring 44 is fixedly connected between the transverse plate 40 and the vertical plate 43. The transverse plate 40 extends into the chamber 20 and abuts against the elliptical block 42, and the moving directions of the two transverse plates 40 are opposite. In the initial state, the two short-axis ends of the elliptical block 42 respectively abut against the two transverse plates 40.

[0033] A through hole is vertically formed at one end of the transverse plate 40 away from the elliptical block 42. A movable block 50 is slidably connected vertically in the through hole. A first spring 51 is fixedly connected between the movable block 50 and the transverse plate 40. The bottom of the arc groove 41 is located on the movement track of the movable block 50. It further includes a pressing mechanism for simultaneously pressing the two movable blocks 50 to move vertically.

A worm gear 55 meshing with the worm 54 and cam bodies 56 located at both ends of the linkage shaft are coaxially connected to the linkage shaft, that is, the worm gear 55 and the two cam bodies 56 are both coaxially connected to the linkage shaft. The worm gear 55 is located in the chamber 20, and the cam body 56 abuts against the linkage block 53. In the initial state, the convex part of the cam body 56 is vertically upward.

[0034] The specific implementation process is as follows: During use, place the seat slide rail 60 on the placement table 12.

[0035] Start the motor 33. The output shaft of the motor 33 drives the drive shaft to rotate. The drive shaft drives the cylindrical cam 34 to rotate. The cylindrical cam 34 drives the guide block 35 to move upward through the curve groove. The guide block 35 drives the rack 31 to move upward through the side block 37 and the bottom block 38. The rack 31 meshes with the gear 30 to drive the gear 30 to rotate. The gear 30 drives the arc block 22 and the elastic layer 25 to rotate through the rotating shaft, the wall block 21, and the wall shaft 23, so that the elastic layer 25 abuts against the seat slide rail 60. Then turn off the motor 33 to achieve the stop of the arc block 22 and the elastic layer 25, that is, use the elastic layer 25 to press and position the seat slide rail 60. And because the thickness of the elastic layer 25 gradually increases from the free end of the arc block 22 to the other end of the arc block 22, therefore, according to the size of the seat slide rail 60, the rotation amplitude of the arc block 22 and the elastic layer 25 can change accordingly, so as to be applicable to the positioning of seat slide rails 60 of different sizes. In this embodiment, the seat slide rails 60 can be placed on the placing tables 12 on both sides, that is, two seats can be pressed and positioned at the same time, and the working efficiency is higher.

[0036] In the initial state, the two short-axis ends of the elliptical block 42 respectively abut against the two transverse plates 40. During the rotation of the drive shaft, the drive shaft drives the elliptical block 42 to rotate, so that the two short-axis ends of the elliptical block 42 gradually move away from the two transverse plates 40, while the two long-axis ends of the elliptical block 42 gradually approach the two transverse plates 40. Therefore, the rotation of the elliptical block 42 can be used to simultaneously squeeze the two transverse plates 40 to move horizontally, so that the two transverse plates 40 move away from each other and the second spring 44 is compressed. Therefore, during the rotation of the drive shaft, the arc block 22 and the elastic layer 25 rotate, and at the same time the transverse plates 40 move horizontally, so that the transverse plates 40 move horizontally in the arc groove 41, that is, the two transverse plates 40 move away from each other. The arc groove 41 at the top of the arc block 22 is in frictional contact with both sides of the transverse plate 40 along the length direction, so as to guide the movement of the arc block 22 and the elastic layer 25. And when the elastic layer 25 presses the seat slide rail 60, it will deform. If there is no restriction of the arc block 22 by the transverse plate 40 through the arc groove 41, the arc block 22 and the elastic layer 25 may shake or shift. Therefore, the frictional contact between the transverse plate 40 and the arc groove 41 can prevent the arc block 22 and the elastic layer 25 from moving and shifting, and ensure the pressing and positioning of the seat slide rail 60.

[0037] During the lateral movement of the transverse plate 40, the transverse plate 40 drives the movable block 50 to move synchronously, so that the movable block 50 is on the side away from the boss 11 in the arc-shaped groove 41, that is, the left movable block 50 is at a position close to the left side in the left arc-shaped groove 41, and the right movable block 50 is at a position close to the right side in the right arc-shaped groove 41; and during the lateral movement of the transverse plate 40, the transverse plate 40 drives the linkage block 53 to move synchronously through the movable block 50, so that the linkage block 53 is in frictional contact with the cam body 56; during the rotation of the drive shaft, the drive shaft drives the worm 54 to rotate, the worm 54 meshes with the worm gear 55 to drive the linkage shaft to rotate, the linkage shaft drives the two cam bodies 56 to rotate synchronously, so that the convex part of the cam body 56 gradually approaches the linkage block 53. Therefore, the rotation of the cam body 56 can be used to squeeze the linkage block 53 to drive the movable block 50 to move downward, and the first spring 51 is compressed; during the downward movement of the movable block 50, the movable block 50 presses the bottom of the arc-shaped groove 41 to drive the arc-shaped block 22 and the elastic layer 25 to move downward, the torsion spring deforms, so that the elastic layer 25 deforms more, and further makes the elastic layer 25 contact the seat slide rail 60 more fully, that is, strengthens the pressing and positioning effect on the seat slide rail 60.

[0038] After the positioning of the seat slide rail 60 is completed, the first cylinder 15 is started, the output shaft of the first cylinder 15 drives the top block 16 and the welding assembly 13 to move laterally, and the output shaft of the second cylinder 17 drives the welding assembly 13 to move vertically, so that the position of the welding assembly 13 can be adjusted according to the welding position requirements to complete the welding work.

[0039] The above are only embodiments of the present invention, and specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
