Description

Technical Field

[0001] This utility model relates to the field of positioning clamp technology, and in particular to a precise positioning treadmill bracket clamp. Background Technology

[0002] Currently, the production of treadmill brackets requires first fixing various types of profiles to a welding platform using fixtures, and then automatically welding them using a welding robot. During the welding process, since the structure typically consists of multiple pipes and stamped sheet metal parts, the welding precision directly affects the overall structural strength and assembly compatibility of the machine. When welding various hinge lugs onto the bracket, traditional positioning devices first position the lugs using positioning blocks, then use pins to prevent displacement of the sheet metal parts, and finally use clamping fixtures to achieve omnidirectional fixation. The various pins and fixtures use a separate structure, requiring them to be removed from the welding table during use. This results in an excessive number and cluttered fixture components on the welding table. Therefore, it is necessary for those skilled in the art to improve upon the shortcomings of existing treadmill bracket welding fixtures. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a precise positioning treadmill bracket clamp, which combines positioning pins and positioning blocks to achieve lateral and longitudinal positioning functions, thereby simplifying the positioning clamp.

[0004] The specific technical solution is as follows:

[0005] A precise positioning treadmill bracket clamp includes a welding platform. A first clamping assembly for positioning a bracket rod is provided on one side of the welding platform. The first clamping assembly includes a positioning support, a movable positioning clamp, and a first clamping clamp. The positioning support is distributed at both ends of the welding platform and supports and positions both ends of the bracket rod. The movable positioning clamp includes a hinge seat disposed on one side of the bracket rod and a positioning block hinged to the hinge seat. After flipping, the positioning block is embedded into a U-shaped hinge on the bracket rod for positioning. The first clamping clamp is used to press and fix the top of the flipped positioning block.

[0006] The positioning block has a movable groove along its length, with one end open. A pressure block is provided in the movable groove, with one end supported by a support spring and the other end extending to the outside of the positioning block through the opening. The pressure block has symmetrical grooves on both sides, with the side of the groove closest to the spring being inclined. Receiving grooves are provided on both sides of the movable groove, with a through hole at one end of the two receiving grooves that are far apart. A movable pin is provided in the receiving groove, with a retaining ring and a compression spring on the movable pin. The compression spring is supported on the retaining ring, causing one end of the movable pin to press against the side wall of the pressure block, and the other end of the movable pin to pass through the through hole and extend outward, thereby cooperating with the hinge holes on both sides of the hinge to achieve positioning.

[0007] Furthermore, each of the positioning supports is provided with an abutment block on one side for abutting and limiting one side of the support rod, and the first clamp assembly also includes a pressing clamp, which presses against the other side of the support rod and cooperates with the abutment block to press and fix the support rod.

[0008] Furthermore, a sheet metal connector is placed on the positioning support on the other side of the support rod, and a limiting block for positioning the sheet metal connector is provided at one end of the positioning support. The first clamping assembly also includes a second clamping clamp, which is disposed on one side of the positioning support and clamps and fixes the connector on the positioning support.

[0009] Furthermore, a second clamping assembly is provided on the other side of the welding platform. The second clamping assembly includes two positioning seats, one limiting seat, and a third clamping clamp. The two positioning seats are distributed left and right and support the two ends of the support rod respectively. The limiting seat is located at one end of the welding platform and abuts against and limits one end of the support rod. The third clamping clamp clamps and fixes the top of the middle part of the support rod.

[0010] Furthermore, one end of the pressure block and one end of the movable groove are both provided with grooves for positioning and supporting the spring.

[0011] Furthermore, the end of the movable pin near the groove has an arc-shaped structure, and the edge of the end of the movable pin away from the groove is chamfered.

[0012] Furthermore, the diameter of the retaining ring is adapted to the diameter of the receiving groove.

[0013] The beneficial effects of this utility model are reflected in:

[0014] (1) Compared with the prior art, the present invention integrates the movable pin into the positioning block. The movable pin can be extended or retracted by pressing or releasing the pressure block, so that there is no need for an additional pin rod to laterally insert and position the positioning block and the U-shaped hinge, which simplifies the fixture structure and makes the operation simple and convenient.

[0015] (2) The welding platform of this utility model is equipped with two sets of clamping assemblies, which are used to clamp and fix the front and back sides of the support rod respectively, thus meeting the welding positioning requirements of the sheet metal parts on the front and back sides of the treadmill support rod.

[0023] Please see the appendix Figure 1-4This embodiment provides a precise positioning treadmill bracket fixture for welding and assembling various sheet metal parts of the treadmill bracket support rod 12. The fixture includes a welding platform 1, and a first clamping assembly 2 for positioning the support rod 12 is provided on one side of the welding platform 1 to meet the welding process of the top surface of the support rod. The first clamping assembly 2 includes a positioning support 3, a movable positioning clamp 4, and a first clamping clamp 5. The positioning support 3 is distributed at both ends of the welding platform 1 and supports and positions both ends of the support rod. There are two movable positioning clamps 4, which are distributed left and right. Each movable positioning clamp 4 includes a hinge seat 41 set on one side of the support rod and a positioning block 42 hinged to the hinge seat 41. The positioning block 42 has a raised rectangular structure. After the positioning block 42 is flipped, it is embedded into the U-shaped hinge 13 on the support rod and positioned. Before positioning, the U-shaped hinge is placed on the top surface of the support rod. Then, the positioning block 42 is flipped so that it is embedded in the inside of the U-shaped hinge. Then, the first clamping clamp 5 is used to clamp and fix the top of the flipped positioning block 42 so that the welding robot can weld and fix the U-shaped hinge 13 on the top of the support rod.

[0024] The positioning block 42 has a movable groove 421 along its length at its center. One end of the movable groove 421 extends outward and is open. A rectangular pressing block 422 is provided in the movable groove 421. One end of the pressing block 422 is supported by a supporting spring 4223, and the other end of the pressing block 422 extends outward through the opening to the outside of the positioning block 42. Grooves 4221 are symmetrically formed on both side walls of the pressing block 422. The side of the groove 4221 near the spring is inclined. Receiving grooves 423 are formed on both sides of the movable groove 421. A through hole 4231 is provided at one end of the groove 423 away from the groove. A movable pin 424 is provided in the groove 423. A retaining ring 4241 and a compression spring 4242 are provided on the movable pin 424. The diameter of the retaining ring is adapted to the diameter of the groove. The compression spring 4242 is supported on the retaining ring 4241 and causes one end of the movable pin to press against the side wall of the pressure block 422. At this time, the compression spring is in a compressed state. The other end of the movable pin 424 passes through the through hole 4231 and extends outward, thereby cooperating with the hinge holes on both sides of the hinge to achieve positioning. By pressing the pressure block 422, one end of the movable pin 424 is inserted into the groove 4221 on the pressure block, and the other end of the movable pin 424 is retracted into the through hole 4231 under the action of the compression spring 4242. After the positioning block 42 is inserted into the hinge, the pressure block 422 is released, the pressure block moves and causes one end of the movable pin to move under the cooperation of the inclined surface and finally move to the side wall of the pressure block 422, so that the movable pin 424 is inserted into the hinge hole of the hinge to achieve positioning.

[0025] In this embodiment, the positioning support 3 is provided with abutment blocks 31 on one side for abutting and limiting one side of the support rod, and the first clamp assembly 2 also includes a pressing clamp 6, which presses against the other side of the support rod and cooperates with the abutment blocks 31 to press and fix the support rod.

[0026] In this embodiment, a sheet metal connector 14 is placed on the positioning support 3 on the other side of the support rod. One side of the sheet metal connector is in close contact with the side wall of the support rod. One end of the positioning support 3 is provided with a limiting block 32 for positioning one end of the sheet metal connector. The first clamping assembly 2 also includes a second clamping clamp 7. The second clamping clamp 7 is disposed on one side of the positioning support 3 and clamps and fixes the connector on the positioning support 3.

[0027] In this embodiment, a second clamping assembly 8 is provided on the other side of the welding platform 1. After welding, the support rod 12 is rotated 180 degrees and placed on the second clamping assembly 8 for positioning, thereby welding the other side of the sheet metal connector 14. The second clamping assembly 8 includes two positioning seats 9, a limiting seat, and a third clamping clamp 11. The two positioning seats 9 are distributed left and right and support the two ends of the support rod 12 respectively. The limiting seat is set at one end of the welding platform 1 and abuts against and limits one end of the support rod. The third clamping clamp 11 clamps and fixes the top of the middle part of the support rod.

[0028] A support rod is positioned on the first clamp assembly 2 and the second clamp assembly 8 on the welding platform 1. The two support rods are subjected to different welding processes. After the support rod 12 on the first clamp assembly 2 is welded, it is rotated 180 degrees and placed on the second clamp assembly 8 for fixation and waiting for welding. After the support rod on the second clamp assembly 8 is welded, it is removed and installed on other welding platforms 1 to weld with other supports. By adopting multiple welding processes, the overall welding and forming of the treadmill support is completed.

[0029] In this embodiment, one end of the pressure block 422 and one end of the movable groove 421 are provided with a groove 4222 for positioning the support spring 4223, thereby preventing the support spring 4223 from shifting.

[0030] In this embodiment, the end of the movable pin 424 near the groove 4221 has an arc-shaped structure. This arc-shaped structure, in conjunction with the inclined surface of the groove 4221, allows it to move flexibly on the side wall of the pressure block 422. The edge of the movable pin 424 away from the groove 4221 is chamfered so that the movable pin 424 can be inserted into the hinge hole of the hinge member.

[0031] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
