Description

Technical Field

[0001] This invention relates to the field of transfer tool technology, specifically to a casting transfer tool. Background Technology

[0002] In the field of machinery manufacturing, castings are core components of various mechanical equipment. Their production process involves multiple steps, including casting, machining, and assembly. The transfer links between these steps are crucial to production efficiency and product quality. For the batch transfer of cylindrical castings, casting turnover transfer racks are widely used in factory workshops as a typical tool. Relying on equipment such as forklifts, the efficient transfer of cylindrical castings between different workstations and workshops can be achieved.

[0003] Existing turnover racks for cylindrical castings typically have multiple symmetrically arranged inclined frames on the frame to prevent them from shifting and rolling during transport. These inclined frames abut against the sides of the cylindrical casting, forming a clamping and limiting structure from both sides to position the casting. However, the structural design of this type of turnover rack only focuses on the basic function of "static support" and lacks adaptive optimization for bumpy conditions during transport.

[0004] In actual production, when forklifts transport such turnover racks through bumpy areas such as speed bumps and potholes, although the inclined frame clamps the column casting from both sides, it is still inevitable that the casting and the inclined frame of the transfer rack will experience severe vibration, collision or scraping. Under such conditions, the surface quality of the casting will be severely degraded: the cylindrical surface of the column casting will have annular scratches and metal peeling. If it is a machined mating surface, it will directly lose its precision and sealing performance; if it is a blank surface, it will greatly increase the difficulty and cost of subsequent grinding processes. Summary of the Invention

[0005] To solve the above-mentioned technical problems, a casting transfer tool is provided, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a casting transfer tool, the tool including a positioning bracket, the positioning bracket including a frame, the front and rear sides of the frame being provided with inverted V-shaped limiting rods, the two ends of the limiting rods being fixedly connected to the horizontal and vertical rods of the frame respectively, the tool also including a pressure-absorbing and shock-absorbing structure, the pressure-absorbing and shock-absorbing structure being two sets, the two sets of pressure-absorbing and shock-absorbing structures being symmetrically arranged on the front and rear sides of the frame;

[0007] The pressure-absorbing and shock-absorbing structure includes a bearing seat, a fixed cylinder, and a positioning roller. The bearing seat is horizontally fixed to the side wall of the frame crossbar. The fixed cylinder has a hollow interior and is vertically fixed to the top surface of the bearing seat. The fixed cylinder has a 7-shaped rail-limiting slot on the side of its wall facing the frame. The positioning roller can slide along the rail-limiting slot in a 7-shaped manner. The fixed cylinder has a built-in threaded drive assembly that cooperates with the positioning roller.

[0008] Compared with the prior art, the advantages of the present invention are as follows:

[0009] (1) By setting up a pressure-resistant and shock-absorbing structure, the positioning pressure is achieved by using the shaft hole of the column casting. Under the adjustment of the thread drive group, the positioning pressure roller completes the step-by-step action along the T-shaped limit rail gap - firstly, it deflects precisely along the horizontal section of the limit rail gap towards the casting and enters the shaft hole of the casting; then it slides down along the vertical section of the limit rail gap until it tightly presses the inner wall of the shaft hole. In this way, the positioning pressure rollers in the two sets of pressure-resistant and shock-absorbing structures form a counter-cooperation and apply pressure synchronously from both sides of the shaft hole of the casting, firmly locking the casting within the limited range of the frame to prevent the casting from moving up and down when it is vibrated and colliding with the frame.

[0010] (2) By setting the positioning pressure roller, when the positioning pressure roller is embedded in the shaft hole of the casting and pressed down to the preset position, air can be injected into the air circuit system through the air inlet. The gas enters the slot through exhaust channel 2 and exhaust channel 1, thereby causing the airbag fitted on the outer wall of the extrusion roller to expand. The expanded airbag can form a tight and flexible contact with the inner wall of the shaft hole. It can enhance the radial clamping force on the casting through the uniformly distributed air pressure, avoiding scratches or precision damage caused by the hard contact between the traditional rigid pressure roller and the inner wall of the shaft hole. It can also absorb the impact energy generated by the transport bumps by the elastic deformation of the airbag, weakening the transmission of vibration to the casting. Attached Figure Description

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] Reference Figure 1-4 As shown, a casting transfer tool is provided for the stable support of column-shaped castings. The tool includes a positioning bracket and a pressure-absorbing and shock-absorbing structure.

[0019] The positioning bracket includes a frame 1, and the front and rear sides of the frame 1 are provided with inverted V-shaped limiting rods 2. The two ends of the limiting rods 2 are respectively fixed to the horizontal and vertical rods of the frame 1.

[0020] By setting up the positioning bracket, the inverted V-shaped limiting rod 2 forms a ring-shaped radial limit from both sides of the column casting. Combined with the bottom support of the frame 1, it can initially constrain the radial displacement and circumferential rolling of the column casting, preventing it from shifting or rolling during transportation, and laying a stable support foundation for the subsequent pressure and shockproof structure.

[0021] Furthermore, referring to Figure 1-4 As shown, it is worth noting that there are two sets of pressure-absorbing and shock-absorbing structures, which are symmetrically arranged on the front and rear sides of the frame 1.

[0022] The pressure-absorbing and shock-absorbing structure includes a bearing seat 5, a fixed cylinder 6, and a positioning roller. The bearing seat 5 is horizontally fixed to the side wall of the crossbar of the frame 1. The fixed cylinder 6 has a hollow interior and is vertically fixed to the top surface of the bearing seat 5. The side of the fixed cylinder 6 facing the frame 1 has a 7-shaped rail-limiting slot 7. The positioning roller can slide along the rail-limiting slot 7 in a 7-shaped manner. The fixed cylinder 6 has a built-in threaded drive assembly that cooperates with the positioning roller.

[0023] By setting up a pressure-absorbing and shock-absorbing structure, the positioning and pressure are achieved using the shaft hole of the column casting. Under the adjustment of the threaded drive group, the positioning pressure roller completes a step-by-step action along the 7-shaped limiting rail gap 7—first, it deflects precisely towards the casting along the horizontal section of the limiting rail gap 7 and enters the shaft hole of the casting; then, it slides downward along the vertical section of the limiting rail gap 7 until it tightly presses against the inner wall of the shaft hole. In this way, the positioning pressure rollers in the two sets of pressure-absorbing and shock-absorbing structures cooperate with each other and apply pressure simultaneously from both sides of the shaft hole of the casting, firmly locking the casting within the limited range of the frame 1 to prevent the casting from moving up and down when subjected to vibration and colliding with the frame 1.

[0024] Furthermore, referring to Figure 4 As shown, it is worth noting that the positioning roller includes a squeezing roller 11 and an airbag 13 fitted on its outer wall, the airbag 13 being made of polyester fiber.

[0025] The outer wall of the extrusion roller 11 is also surrounded by a groove 12 that communicates with the airbag 13. The inner wall of the extrusion roller 11 is vertically connected to an exhaust channel 14 that communicates with the inner side of the groove 12. One end of the extrusion roller 11 is provided with an exhaust channel 4 that communicates with the exhaust channel 14. An inflation nozzle 3 with a built-in valve core is fixedly inserted in the end of the exhaust channel 4 that communicates with the outside.

[0026] By setting the positioning pressure roller, after the positioning pressure roller is embedded in the shaft hole of the casting and pressed down to the preset position, air can be injected into the air circuit system through the air inlet 3. The gas enters the slot 12 through the exhaust channel 2 4 and the exhaust channel 14, thereby causing the airbag 13 fitted on the outer wall of the extrusion roller 11 to expand. The expanded airbag 13 can form a tight and flexible contact with the inner wall of the shaft hole. This not only enhances the radial clamping force on the casting through the uniformly distributed air pressure, avoiding scratches or precision damage caused by the hard contact between the traditional rigid pressure roller and the inner wall of the shaft hole; but also absorbs the impact energy generated by the transport bumps by the elastic deformation of the airbag, weakening the transmission of vibration to the casting.

[0027] Furthermore, referring to Figure 3 As shown, it is worth noting that the thread drive assembly includes a screw vertically disposed in the fixed cylinder 6, a nut seat 9 threadedly connected to the screw body, and a sliding column 10 slidably disposed in the rail gap 7. The sliding column 10 is fixed between the outer wall of the nut seat 9 and the other end of the extrusion roller 11.

[0028] The top of the lead screw rotates through the fixed cylinder 6 and is fixed with a handle 8;

[0029] By setting up the threaded drive assembly, the rotational motion of the lead screw can be converted into the precise trajectory motion of the positioning pressure roller: when the lead screw is rotated, the nut seat 9 connected by the thread moves up and down along the axis of the lead screw, while driving the slide column 10 to slide along the 7-shaped limiting gap 7. Because the horizontal and vertical sections of the limiting gap 7 are distributed in a 7 shape, the slide column 10 first drives the extrusion roller 11 to deflect horizontally towards the casting along the horizontal section until the positioning pressure roller is embedded in the shaft hole; then the slide column 10 drives the extrusion roller to slide downward along the vertical section, thereby gradually pressing the inner wall of the shaft hole.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
