Description

Technical Field

[0001] This utility model belongs to the technical field of ball joint connecting rod processing equipment, specifically relating to a stress-relieving heat treatment device for guide connecting rods. Background Technology

[0002] Stress-relief heat treatment of ball joint connecting rods is used to perform stress-relief annealing on precision-machined guide connecting rods (especially the stress concentration area at the root of the ball joint), eliminating residual internal stress generated during cutting and grinding, preventing deformation or fatigue fracture due to stress release during use, and improving the dimensional stability and reliability of the product.

[0003] In the existing technology, the current process for heat treatment of ball joint connecting rods adopts the method of clamping and heating one by one, which has significant efficiency defects. Due to the lack of automated integrated tooling, operators need to manually complete the positioning, clamping and status confirmation of individual workpieces, which is time-consuming and prone to positioning deviation due to human factors. At the same time, the independent heating mode limits the batch processing capacity, and only a small number of workpieces can be processed per unit time, which is difficult to meet the requirements of large-scale production for cycle time and capacity. Utility Model Content

[0004] The purpose of this invention is to provide a stress-relieving heat treatment device for guide links to solve the problems mentioned in the background art.

[0008] In a preferred embodiment, the support foot has an "L" shape and is mounted on the side wall at the bottom end of the chain conveyor belt.

[0009] In a preferred embodiment, the fixing block is fixedly connected to a heat insulation cylinder on the inner wall of the insertion hole, and the heat insulation cylinder is made of rock wool.

[0010] In a preferred embodiment, a toothed block is slidably connected inside the fixing block, the toothed block penetrates the outer wall of the heat insulation cylinder, the toothed block is movably connected to the heat insulation cylinder, a spring is installed between the toothed block and the fixing block, and the toothed end of the toothed block extends into the insertion hole.

[0011] In a preferred embodiment, the inductor is U-shaped and externally connected to a high-frequency machine.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention involves inserting the welded ball head rod into an insertion hole. The ball head is driven to move by a chain plate, and the connection between the ball head and the rod is inductively heated by an inductor coil, thereby achieving annealing. The heated ball head continues to move with the chain plate conveyor belt.

It is convenient to operate and has high work efficiency. Attached Figure Description

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-5 This utility model provides a stress-relieving heat treatment device for a guide link, including a chain conveyor belt 1 and a support foot 6 installed at the bottom of the chain conveyor belt 1. A heating mechanism 2 is connected to the chain conveyor belt 1. The heating mechanism 2 includes a fixing block 21. The fixing block 21 is fixedly connected to the chain plate of the chain conveyor belt 1. One end of the fixing block 21 is provided with an insertion hole 24 to facilitate the transportation of the ball head. A bearing platform 22 is installed on the side of the chain conveyor belt 1 near the insertion hole 24. An inductor coil 23 is installed on the bearing platform 22. A material ejection mechanism 3 is connected to the chain conveyor belt 1. The material ejection mechanism 3 includes a support plate 32. The support plate 32 is installed at the top of the chain conveyor belt 1. A first sliding plate 33 is slidably connected to the side of the support plate 32 near the bearing platform 22. A second sliding plate 36 is slidably connected to the chain conveyor belt 1 below the first sliding plate 33. Guide rods 34 are installed on both the first sliding plate 33 and the second sliding plate 36 to facilitate the ejection of the rod part of the ball head.

[0018] Specifically, such as Figure 4 As shown, the guide rod 34 has a slide-shaped structure and extends out of the side wall of the chain conveyor belt 1, which facilitates the disengagement of the rod part of the ball head from the insertion hole 24.

[0019] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, a second knob 35 is rotatably connected to the chain conveyor belt 1. The threaded end of the second knob 35 is threadedly connected to the second slide plate 36. A first knob 31 is rotatably connected to the first slide plate 33. The threaded end of the first knob 31 is threadedly connected to the support plate 32, thereby facilitating the adjustment of the distance between a pair of guide rods 34.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, the support foot 6 has an "L" shaped structure and is installed on the side wall at the bottom of the chain conveyor belt 1, thereby preventing the ball head from colliding with the support foot 6.

[0021] Specifically, such as Figure 3 and Figure 5 As shown, the fixing block 21 is fixedly connected to the heat insulation cylinder 7 on the inner wall of the insertion hole 24. The heat insulation cylinder 7 is made of rock wool to provide heat insulation.

[0022] Specifically, such as Figure 5As shown, a toothed block 5 is slidably connected inside the fixed block 21. The toothed block 5 penetrates the outer wall of the heat insulation cylinder 7 and is movably connected to the heat insulation cylinder 7. A spring 4 is installed between the toothed block 5 and the fixed block 21. The toothed end of the toothed block 5 extends into the insertion hole 24, thereby facilitating the limiting of the rod part of the ball head.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the inductor coil 23 is U-shaped and is externally connected to the high-frequency machine.

[0024] The working principle and usage process of this utility model are as follows: The welded ball head rod is inserted into the insertion hole 24. The threaded end of the ball head rod will abut against the teeth of the toothed block 5. The teeth are triangular, thus pushing the toothed block 5 to slide downward. The spring 4 is compressed. Under the action of the spring 4, the thread of the ball head rod will abut tightly against the teeth of the toothed block 5, thus preventing the ball head rod from disengaging from the insertion hole 24. The ball head rod is in close contact with the inner wall of the heat insulation cylinder 7. The chain conveyor belt 1 is started, which drives the fixed block 21 to move, thereby driving the ball head to move. The high-frequency machine connected to the inductor coil 23 is started. The inductor coil 23 is externally connected to the high-frequency machine. The ball head passes through the middle of the "U"-shaped inductor coil 23. When passing through, the connection between the ball head and the rod is heated by induction. This process achieves annealing. The heated ball head continues to move with the chain conveyor belt 1. When the ball head moves between a pair of guide rods 34, the first knob 31 and the second knob 35 are rotated to drive the first slide plate 33 and the second slide plate 36 to slide, changing the distance between the pair of guide rods 34 to be less than the diameter of the ball head. This causes the ball head to slide along the outside of the guide rods 34, and the rod end of the ball head passes between the pair of guide rods 34. The guide rods 34 are in the shape of a slide rail, thus pushing the ball head outward and causing the rod end of the ball head to disengage from the insertion hole 24. The tooth block 5 slides, and the heat insulation cylinder 7 plays a heat insulation role, preventing the fixed block 21 from getting hot and affecting the operation of the chain conveyor belt 1, thereby achieving the purpose of automatic annealing and unloading. The operation is convenient.
