In the heat treatment project, the workpiece needs to be heated in a quenching furnace. Since the temperature in the quenching furnace is extremely high, a hoist is usually used to take and place the workpiece in the quenching furnace.

[0003] In the related art, a Chinese patent with authorization announcement number CN220503115U provides a hanger for a metal heat treatment quenching furnace, which includes a casing, a horizontal plate is inserted into one end of the casing, the horizontal plate slides along the casing, iron chains are installed on the horizontal plate and the casing, and a ring is installed on the iron chain. Grooved blocks are installed below the horizontal plate and the casing, and the grooves of the groove blocks are arranged relative to each other. A clamp is slidably arranged in the groove block, a threaded rod is installed on the clamp, and the threaded rod is threadedly connected to the groove block. When the workpiece is installed on the hanger, the spacing between the groove blocks is adjusted by sliding the horizontal plate along the casing, so that the two ends of the workpiece are inserted into the grooves of the groove block, and then the threaded rod is rotated to move the clamp, and then the clamp clamps the workpiece.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: since the cross plate and the casing are connected by iron chains and rings, the iron chains will swing when the lifting equipment is connected to the rings to lift the workpiece. When there are multiple workpieces to be processed in the quenching furnace at the same time, the swinging of the iron chains will drive the workpieces to move, causing collisions or jams between adjacent workpieces.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a hanger for heat treatment workpiece processing. Figure 1, which comprises a lifting ring 1, a support rod 11 is installed at the bottom of the lifting ring 1, and a driving seat 2 is installed at the bottom of the support rod 11. Guide arms 3 are installed at both ends of the driving seat 2, and telescopic arms 4 are slidably arranged on the guide arms 3. A clamping assembly 5 is installed at one end of the telescopic arm 4 away from the driving seat 2, and the clamping assembly 5 is used to clamp the workpiece. An iron chain 6 is installed between the telescopic arm 4 and the lifting ring 1, and the iron chain 6 is symmetrically arranged, and a tensioning spring 61 is installed between the iron chain 6 and the guide arm 3. When the workpiece is installed on the sling, the distance between the clamped workpieces is adjusted by sliding the telescopic arm 4 along the guide arm 3, so that the two ends of the workpiece are fixed by the clamping assembly 5. When the telescopic arms 4 move away from each other, the tensioning spring 61 gradually extends; when the telescopic arms 4 move closer to each other, the tensioning spring 61 gradually shortens. The iron chain 6 is always in a taut state, so that the iron chain 6 pulls the telescopic arm 4. When the lifting equipment is connected to the lifting ring 1 to drive the workpiece to move, the lifting ring 1 is connected to the telescopic arm 4 by the iron chain 6, the iron chain 6 and the guide arm 3 are tensioned by the tensioning spring 61, and the lifting ring 1 is connected to the driving seat 2 by the support rod 11, so as to reduce the swinging of the iron chain 6, make it less likely for adjacent workpieces to collide or get stuck, and improve the stability during the lifting of workpieces.

[0033] In order to move the telescopic arm 4 along the guide arm 3, refer to Figure 1 and Figure 2 The guide arm 3 has a sliding groove 31 at one end away from the driving seat 2, and the telescopic arm 4 is inserted into the sliding groove 31 at one end close to the driving seat 2. The telescopic arm 4 is slidably connected to the sliding groove 31, and the side wall of the telescopic arm 4 is in contact with the inner wall of the sliding groove 31. A limit groove 32 is provided on the inner wall of the sliding groove 31, and a limit block 33 is slidably arranged in the limit groove 32. The outer wall of the limit block 33 is in contact with the inner wall of the limit groove 32, and the limit block 33 is fixedly connected to the telescopic arm 4. A threaded groove 41 is provided at one end of the telescopic arm 4 located in the sliding groove 31, and a sliding screw 42 is threadedly connected in the threaded groove 41. The end of the sliding screw 42 away from the telescopic arm 4 is rotatably connected to the inner wall of the sliding groove 31. When the sliding screw 42 rotates, the sliding screw 42 drives the telescopic arm 4 to move along the sliding groove 31. Furthermore, the limiting block 33 fixedly connected to the telescopic arm 4 slides in the limiting groove 32 , so that the telescopic arm 4 is not easy to slide out of the sliding groove 31 .

[0034] In order to make the telescopic arm 4 move synchronously, refer to Figure 1 and Figure 2, a driving chamber 7 is provided in the driving seat 2, and a group of transmission gears 71 are rotatably arranged in the driving chamber 7, and the transmission gears 71 are arranged opposite to each other. A transmission shaft 711 is installed between the opposite surface of the transmission gear 71 and the opposite surface of the sliding screw 42, and the transmission shaft 711 penetrates the end wall of the guide arm 3 and the end wall of the driving seat 2, and the guide arm 3 and the driving seat 2 are rotatably connected with the transmission shaft 711 through a bearing. A driving gear 72 is rotatably arranged in the driving chamber 7, and the driving gear 72 is meshed with the transmission gear 71. A driving shaft 721 is installed at the bottom of the driving gear 72, and the driving shaft 721 penetrates the bottom wall of the driving seat 2. The driving shaft 721 is rotatably connected to the bottom wall of the driving seat 2 through a bearing, and a driving button 722 is installed at the bottom of the driving shaft 721. The staff drives the driving button 722 to rotate, and the driving button 722 rotates to drive the driving shaft 721 to rotate, and the driving shaft 721 rotates to drive the driving gear 72. The driving gear 72 rotates to drive the transmission gear 71, and the transmission gear 71 rotates to drive the transmission shaft 711. The rotation of the transmission shaft 711 drives the two sliding screws 42 to rotate simultaneously, thereby causing the two telescopic arms 4 to move simultaneously.

[0035] In order to achieve the effect of clamping the workpiece, refer to Figure 1 and Figure 3 The clamping assembly 5 includes a clamping seat 54, a clamping block 51, a clamping plate 52 and a clamping screw 53. The clamping seat 54 is installed on the end of the telescopic arm 4 away from the driving seat 2, and the clamping block 51 is installed below the clamping seat 54. A clamping groove 511 is provided on the side wall of the clamping block 51, and the clamping groove 511 passes through the end wall of the clamping block 51. The clamping plate 52 is slidably arranged in the clamping groove 511, and the top wall of the clamping plate 52 is rotatably connected to the bottom end of the clamping screw 53, the top end of the clamping screw 53 passes through the clamping block 51, and the clamping screw 53 is threadedly connected to the clamping block 51. When the workpiece is inserted into the clamping groove 511 below the clamping plate 52, the staff then rotates the clamping screw 53 to make the clamping plate 52 abut against the workpiece, thereby achieving the effect of clamping and fixing the workpiece.

[0036] In order to facilitate the clamping groove 511 to face the part of the workpiece to be clamped, refer to Figure 1 and Figure 3, the clamping seat 54 is provided with an adjustment shaft 82, and the adjustment shaft 82 is rotatably connected with the clamping seat 54 through a bearing. The bottom end of the adjustment shaft 82 is welded to the top end of the clamping block 51, and the top end of the adjustment shaft 82 is welded with a connecting rod 91. The top of the clamping seat 54 is provided with an adjustment bracket 8, and the adjustment screw 81 is penetrated through the adjustment bracket 8, and the adjustment screw 81 is threadedly connected with the adjustment bracket 8. The bottom end of the adjustment screw 81 is provided with a connecting sleeve 9, and a connecting groove 92 is provided on the inner wall of the connecting sleeve 9, and a connecting block 93 is slidably provided in the connecting groove 92. The top end of the connecting rod 91 is inserted into the connecting sleeve 9, and the side wall of the connecting rod 91 is welded with the connecting block 93. The staff rotates the adjustment screw 81, and the adjustment screw 81 moves along the height direction of the adjustment bracket 8 while rotating, and then the adjustment screw 81 drives the connecting sleeve 9 to rotate and moves the connecting sleeve 9 along the height direction. While the connecting sleeve 9 and the connecting rod 91 move relative to each other along the height, the connecting sleeve 9 rotates to drive the connecting rod 91 to rotate, and then the connecting rod 91 drives the adjustment shaft 82 to rotate. The adjusting shaft 82 drives the clamping block 51 to rotate, and the clamping groove 511 on the clamping block 51 faces the part of the workpiece to be clamped.

[0037] The implementation principle of a hanger for heat-treated workpiece processing in the embodiment of the present application is as follows: when the workpiece is mounted on the hanger, the driving button 722 is turned to make the telescopic arm 4 drive the clamping seat 54 to move, so as to adjust the spacing between the clamping grooves 511, and then the two ends of the workpiece are inserted into the clamping grooves 511 for fixing. When the telescopic arms 4 move away from each other, the tensioning spring 61 gradually extends; when the telescopic arms 4 move closer to each other, the tensioning spring 61 gradually shortens. The iron chain 6 is always in a taut state, so that the iron chain 6 pulls the telescopic arm 4. When the lifting equipment is connected to the lifting ring 1 to drive the workpiece to move, the iron chain 6 applies a pulling force to the telescopic arm 4, reducing the force on the support rod 11, and the lifting ring 1 and the driving seat 2 form a lateral restriction through the support rod 11, so that the iron chain 6 is not easy to swing laterally, thereby improving the stability during the process of lifting the workpiece. Furthermore, when multiple workpieces are heat-treated at the same time, the workpieces are not easy to move laterally, so that adjacent workpieces are not easy to collide or get stuck.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
