Description

Technical Field

[0001] The present invention relates to the technical field of welding brackets, and more particularly to a welding processing device for metal parts of fitness equipment. Background Art

[0002] A gym is a place for people to exercise. In order to meet people's fitness needs, there are many different fitness equipment placed in the gym. Simple fitness equipment such as horizontal bars will be welded to different degrees during production according to usage requirements to improve the firmness and safety of the horizontal bars and avoid some unexpected situations during use.

[0003] For example, utility model patent CN215469171U discloses a welding bracket for fitness equipment processing. The starting motor box drives the bidirectional threaded rod to rotate, and then drives the threaded block on the surface of the bidirectional threaded rod to move relatively, and adjusts the distance between the two clamping plates to adapt to different sizes of welding equipment for clamping and fixing. The height of the slide bar is adjusted by manually rotating the screwing piece corresponding to the limit groove, which is convenient for fine-tuning the welding height. The clamping plate can be replaced according to the welding equipment. By setting a collection groove at the bottom of the working plate, the welding slag generated by welding is collected and stored, making the working environment more comfortable and convenient for recycling.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: In view of the fact that there is no multi-group clamping structure in the prior art, when facing equipment with an irregular shape, it is impossible to perform an adaptable clamping and stabilizing operation, which is likely to cause instability during the welding of the equipment. To solve this problem, the following technical solutions are proposed:

[0028] Referring to the attached drawings of the specification Figures 1 - 7 , a welding and processing device for metal parts of fitness equipment, as Figure 1 and Figure 2 shown, includes a base 1. A support plate frame 2 is fixedly installed on the top of the base 1. A layer clamping mechanism 3 and a side pushing mechanism 4 are arranged on one side of the support plate frame 2;

[0029] As Figure 3 shown, the layer clamping mechanism 3 includes a toggle rod 31 rotatably installed on the top of the base 1. Threaded grooves are respectively formed on the outer walls of both sides of the toggle rod 31. A turntable 32 is fixedly installed on one side of the toggle rod 31. Two support rods 33 are threadedly connected to the outer wall of the toggle rod 31. The two support rods 33 are symmetrically arranged. The two support rods 33 are horizontally arranged. By rotating the turntable 32, the toggle rod 31 is driven to rotate, and then the two support rods 33 perform synchronous relative movement through the threaded grooves on the outer wall of the toggle rod 31.

[0030] As Figure 3 and Figure 4 shown, a motor 34 is fixedly installed on the top of the support plate frame 2. The motor 34 is vertically arranged. A threaded rod 35 is provided on the top of the motor 34. The threaded rod 35 is vertically upward. A lifting plate 36 is threadedly connected to the outer wall of the threaded rod 35. The lifting plate 36 is horizontally arranged. Two lifting push rods 37 are fixedly installed at the bottom of both sides of the lifting plate 36. The two lifting push rods 37 are vertically downward. The two lifting push rods 37 are symmetrically arranged;

[0031] Piston plates 38 are respectively fixedly installed at the bottoms of the two lifting push rods 37. Air cylinders 39 are arranged on the outer walls of the two piston plates 38. The two air cylinders 39 are fixedly installed on the inner wall of the support plate frame 2. The outer wall of the piston plate 38 is in close fit with the inner wall of the air cylinder 39. The two air cylinders 39 are symmetrically arranged. The motor 34 drives the threaded rod 35 so that the lifting plate 36 can move upward, and then the lifting plate 36 drives the two lifting push rods 37 on both sides to make the piston plates 38 move upward synchronously, that is, the piston plates 38 generate negative pressure in the air cylinders 39.

[0032] AsFigure 3 and Figure 4 As shown in Figure 4 , on one side of each of the two air cylinders 39, a plurality of sleeves 310 are respectively communicated. The plurality of sleeves 310 are fixedly installed on the inner wall of the support plate frame 2. The plurality of sleeves 310 are arranged staggeredly with each other. The plurality of sleeves 310 are arranged horizontally. The inner walls of the plurality of sleeves 310 are respectively provided with telescopic rods 311. The plurality of telescopic rods 311 are arranged horizontally. The plurality of telescopic rods 311 are arranged staggeredly with each other. At this time, the negative pressure in the air cylinder 39 causes the negative pressure in the plurality of sleeves 310 to be synchronized, and the plurality of telescopic rods 311 slide into the sleeves 310 under the action of the negative pressure.

[0033] As Figure 3 and Figure 4 As shown in Figure 4 , on the outer walls of the plurality of telescopic rods 311, extrusion plates 312 are respectively fixedly installed. The plurality of extrusion plates 312 are slidably installed on the outer wall of the support plate frame 2. The plurality of extrusion plates 312 are arranged in pairs symmetrically with each other. The plurality of extrusion plates 312 are arranged perpendicular to the outer wall of the support plate frame 2. The plurality of telescopic rods 311 drive the extrusion plates 312 to move synchronously. Thus, the plurality of extrusion plates 312 clamp the two sides of the equipment from both sides to the middle, and stay at the corresponding positions according to the outer wall shapes of both sides of the equipment.

[0034] As Figure 5 As shown in Figure 5 , the side pushing mechanism 4 includes two sliding push rods 41 slidably installed in the inner wall of the extrusion plate 312. The two sliding push rods 41 are arranged symmetrically with each other. The two sliding push rods 41 are arranged perpendicular to the extrusion plate 312. On the outer walls of the two sliding push rods 41, limiting springs 42 are fixedly installed. The limiting springs 42 are fixedly installed on the outer wall of the extrusion plate 312. The two sliding push rods 41 are pulled by the limiting springs 42 and extend out on one side of the extrusion plate 312.

[0035] As Figure 5 As shown in Figure 5 , on one side of each of the two sliding push rods 41, a slider 43 is respectively hinged. On one side of the two sliders 43, a clamping plate 44 is jointly slidably installed. The clamping plate 44 is arranged parallel to the extrusion plate 312. A rubber pad 45 is fixedly installed on the outer wall of the clamping plate 44. When the plurality of extrusion plates 312 on both sides approach the outer walls of both sides of the equipment, the rubber pad 45 driven by the clamping plate 44 first fits the outer wall of the equipment, and during the continuous approach process, the clamping plate 44 is squeezed to deflect correspondingly, that is, the angle of the outer wall of the equipment causes the clamping plate 44 to fit it correspondingly. Thus, the clamping plate 44 drives the rubber pad 45 to completely fit the outer wall of the equipment.

[0036] During specific implementation, by rotating the turntable 32 to drive the toggle rod 31 to rotate, further, through the thread grooves on the outer wall of the toggle rod 31, the two support rods 33 move synchronously relatively. The motor 34 drives the threaded rod 35 so that the lifting plate 36 can move upward. Further, the lifting plate 36 drives the lifting push rods 37 on both sides so that the piston plate 38 moves upward synchronously. That is, the piston plate 38 causes a negative pressure to be generated in the air cylinder 39;

[0037] At this time, the negative pressure in the air cylinder 39 causes the negative pressure in the multiple sleeves 310 to be synchronized. The multiple telescopic rods 311 slide into the sleeves 310 under the negative pressure. The multiple telescopic rods 311 drive the pushing plates 312 to move synchronously. The multiple pushing plates 312 clamp the two sides of the equipment from the two side positions to the middle, and stay at the corresponding positions according to the outer wall shapes of the two sides of the equipment, so as to freely clamp and adapt to the outer shapes of the two sides of the equipment;

[0038] Meanwhile, when the multiple pushing plates 312 on both sides approach the outer walls of the equipment on both sides, the rubber pads 45 driven by the clamping plates 44 first fit the outer walls of the equipment, and during the continuous approaching process, the clamping plates 44 are squeezed to deflect correspondingly, that is, the angle of the outer wall of the equipment causes the clamping plates 44 to fit correspondingly. The clamping plates 44 drive the rubber pads 45 to completely fit the outer walls of the equipment for stable clamping.

[0039] Embodiment 2: Aiming at the lack of a pushing structure during the welding of equipment in the prior art, which cannot ensure that the equipment can stably and accurately approach the clamping area, greatly affecting the clamping stability during welding. To solve this problem, the following technical solutions are proposed:

[0040] As Figure 6 and Figure 7 shown, a top-pushing mechanism 5 is arranged on the top of the base 1. The top-pushing mechanism 5 includes two same-belt plates 51 fixedly installed on the outer wall of the lifting plate 36. The two same-belt plates 51 are slidably installed on the inner wall of the support plate frame 2. The two same-belt plates 51 are symmetrically arranged with each other. When the lifting plate 36 moves upward, it drives the two same-belt plates 51 to move upward synchronously.

[0041] As Figure 6 and Figure 7 shown, a pushing plate 52 is fixedly installed on one side of the two same-belt plates 51 together. A supporting spring 53 is fixedly installed on the top of the pushing plate 52. A squeezing block 54 is fixedly installed on the top of the supporting spring 53. The squeezing block 54 is slidably installed on the outer wall of the base 1. The top of the squeezing block 54 is arranged in an inclined shape;

[0042] During specific implementation, when the lifting plate 36 moves upward, it drives the two same-belt plates 51 to move upward synchronously. Then the two same-belt plates 51 drive the pushing plate 52 to move upward and squeeze the supporting spring 53. At this time, the squeezing block 54 moves upward under the thrust and squeezes the bottom outer wall of the equipment, so as to squeeze and push the equipment inward through its inclined surface, facilitating the equipment to approach the clamping area.

[0043] The following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense, which can be a mechanical connection or an electrical connection, or can be the internal communication of two components, and can be directly connected. The terms "upper", "lower", "left", "right", etc. are only used to indicate the relative position relationship. When the absolute position of the object being described changes, the relative position relationship may change;

[0044] Second, in the attached drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0045] Finally, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
