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.

[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 implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0024] 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 adapted 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: Refer to the attached drawings of the specification Figures 1-7 , a welding processing device for metal parts of fitness equipment, as Figure 1 and Figure 2 shown, including a base 1, a support plate frame 2 is fixedly installed on the top of the base 1, and a layer clamping mechanism 3 and a side pushing mechanism 4 are arranged on one side of the support plate frame 2; As Figure 3 shown, the layer clamping mechanism 3 includes a toggle rod 31 rotatably installed on the top of the base 1. Thread 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 in a horizontal state. 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 thread grooves on the outer wall of the toggle rod 31.

[0025] 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 in a vertical state. 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 in a horizontal state. Lifting rods 37 are fixedly installed at the bottoms of both sides of the lifting plate 36. The two lifting rods 37 are vertically downward. The two lifting rods 37 are symmetrically arranged; Piston plates 38 are respectively fixedly installed at the bottoms of the two lifting 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 lifting 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.

[0026] As Figure 3 and Figure 4As shown, one side of the two air cylinders 39 is respectively connected with a plurality of sleeves 310, and the plurality of sleeves 310 are fixedly mounted on the inner wall of the support plate frame 2, and the plurality of sleeves 310 are staggered with each other, and the plurality of sleeves 310 are arranged in a horizontal state, and the inner walls of the plurality of sleeves 310 are respectively provided with telescopic rods 311, and the plurality of telescopic rods 311 are arranged in a horizontal state, and the plurality of telescopic rods 311 are staggered with each other. At this time, the negative pressure in the air cylinder 39 causes the plurality of sleeves 310 to have synchronous negative pressure, and the plurality of telescopic rods 311 slide into the sleeve 310 under the negative pressure.

[0027] like Figure 3 and Figure 4 As shown, the outer walls of the multiple telescopic rods 311 are respectively fixedly installed with pushing plates 312, and the multiple pushing plates 312 are slidably installed on the outer wall of the support plate frame 2. The multiple pushing plates 312 are symmetrically arranged in pairs, and the multiple pushing plates 312 and the outer wall of the support plate frame 2 are perpendicular to each other. The multiple telescopic rods 311 drive the pushing plates 312 to move synchronously, so that the multiple pushing plates 312 are clamped on both sides of the middle equipment and stay at corresponding positions according to the shape of the outer walls on both sides of the equipment.

[0028] like Figure 5 As shown, the side push mechanism 4 includes two sliding push rods 41 slidably mounted on the inner wall of the pushing plate 312, the two sliding push rods 41 are symmetrically arranged, the two sliding push rods 41 and the pushing plate 312 are perpendicular to each other, and the outer walls of the two sliding push rods 41 are fixedly mounted with limiting springs 42, the limiting springs 42 are fixedly mounted on the outer wall of the pushing plate 312, and the two sliding push rods 41 are pulled out from one side of the pushing plate 312 by the limiting springs 42.

[0029] like Figure 5 As shown, one side of the two sliding push rods 41 is respectively hinged with a slider 43, and one side of the two sliders 43 is jointly slidably installed with a clamping plate 44, the clamping plate 44 and the pushing plate 312 are arranged parallel to each other, and the outer wall of the clamping plate 44 is fixedly installed with a rubber pad 45. When the multiple pushing plates 312 on both sides approach the outer walls of the equipment on both sides, the rubber pad 45 driven by the clamping plate 44 first fits the outer wall of the equipment, and squeezes the clamping plate 44 to deflect accordingly during the continuous approach process, that is, the angle of the outer wall of the equipment makes the clamping plate 44 fit therewith accordingly, so that the clamping plate 44 drives the rubber pad 45 to completely fit the outer wall of the equipment.

[0030] In the specific implementation, the dial 32 is rotated to drive the toggle rod 31 to rotate, and then the threaded groove on the outer wall of the toggle rod 31 causes the two support rods 33 to move relatively synchronously, and the motor 34 drives the threaded rod 35 to enable the lifting plate 36 to move upward, and then the lifting plate 36 drives the lifting and pushing rods 37 on both sides to enable the piston plate 38 to move upward synchronously, that is, the piston plate 38 generates negative pressure in the air cylinder 39; 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 extrusion plates 312 to move synchronously. The multiple extrusion 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 the two sides of the equipment according to its outer shape; Meanwhile, when the multiple extrusion plates 312 on both sides approach the outer walls of the two sides of the equipment, the rubber pads 45 driven by the clamping plates 44 first fit the outer walls of the equipment, and during the continuous approach 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 it correspondingly. The clamping plates 44 drive the rubber pads 45 to completely fit the outer walls of the equipment for stable clamping.

[0031] Embodiment 2: In view of the lack of a pushing structure for welding 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 solution is proposed: As Figure 6 and Figure 7 shown, a top-pushing mechanism 5 is provided on the top of the base 1. The top-pushing mechanism 5 includes two co-belt plates 51 fixedly installed on the outer wall of the lifting plate 36. The two co-belt plates 51 are slidably installed on the inner wall of the support plate frame 2. The two co-belt plates 51 are symmetrically arranged. When the lifting plate 36 moves upward, it drives the two co-belt plates 51 to move upward synchronously.

[0032] As Figure 6 and Figure 7 shown, a pushing plate 52 is fixedly installed on one side of the two co-belt plates 51. A supporting spring 53 is fixedly installed on the top of the pushing plate 52. A pushing block 54 is fixedly installed on the top of the supporting spring 53. The pushing block 54 is slidably installed on the outer wall of the base 1. The top of the pushing block 54 is arranged in an inclined shape; In specific implementation, when the lifting plate 36 moves upward, it drives the two co-belt plates 51 to move upward synchronously. Then the two co-belt plates 51 drive the pushing plate 52 to move upward and squeeze the supporting spring 53. At this time, the pushing block 54 moves upward under the thrust and squeezes the bottom outer wall of the equipment, so as to push the equipment inward through its inclined surface, facilitating the equipment to approach the clamping area.

[0033] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, and can also be the communication inside two components. It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship.
