Description

Technical Field

[0001] The utility model relates to the technical field of electric hoist processing, in particular to electric hoist parts processing equipment. Background Art

[0002] With the development of domestic and foreign industries, the new Chinese hoist has been recognized by the market for its compact structure, excellent performance and better appearance quality, becoming the mainstream of the market and the development direction of the industry. As an important part of the new Chinese hoist, the friction ring is used to fix the operating structure on both sides, and cooperate with the hollow tube to adjust the wheel spacing to ensure the stable operation of the hoist.

[0003] At present, the incision of the friction ring is generally processed on a milling machine with a vise. The vise clamping method of the friction ring has a small clamping surface and requires a large clamping force, which will cause a certain amount of deformation of the friction ring, and thus may affect the quality of the friction ring incision.

[0004] Therefore, we designed an electric hoist parts processing equipment. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses an electric hoist parts processing equipment.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] An electric hoist parts processing equipment, comprising a frame, a cutting device for cutting a workpiece is provided at one end of the frame, a cutting groove is provided on the top surface of the frame at a position corresponding to the cutting part of the cutting device, a clamping device for clamping the workpiece is provided on the top surface of the frame, the clamping device comprises an eight-shaped baffle plate provided on the top surface of the frame and symmetrically arranged on both sides of the cutting groove, and a V-shaped clamping block opposite to the large end of the eight-shaped baffle plate is provided;

[0008] The clamping device also includes a driving cylinder for driving the V-shaped clamping block to move closer to or away from the eight-shaped baffle plate, so as to clamp or release the workpiece.

[0009] Preferably, a cylinder baffle is provided at one end of the frame top surface facing away from the cutting device, and the drive cylinder is provided at one end of the cylinder baffle corresponding to the cutting device, and the output shaft of the drive cylinder is correspondingly connected to the closed end of the V-shaped clamping block.

[0010] Preferably, the closed end of the V-shaped clamping block is hinged to the output shaft of the driving cylinder via a vertical pin.

[0011] Preferably, there is a gap between the V-shaped clamping block and the top surface of the frame.

[0012] Preferably, the cutting device comprises a lifting assembly, and the lifting part of the lifting assembly is provided with a saw for cutting the workpiece.

[0013] Preferably, the lifting assembly includes a vertical lead screw rotatably connected to the frame, the lead screw portion of the vertical lead screw is matched with a lead screw nut, a connecting frame is provided on one side of the lead screw nut corresponding to the clamping device, and the connecting frame is slidably connected to the frame up and down, and the sawing machine is installed on the connecting frame;

[0014] The lifting assembly also includes a reduction motor for driving the vertical lead screw to rotate.

[0015] Preferably, the frame is provided with a vertical slide rail, and the connecting frame is provided with a slider slidably connected to the vertical slide rail.

[0016] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0017] 1. The setting of the clamping device can drive the V-shaped clamping block and the eight-shaped baffle plate to cooperate by driving the cylinder, and complete the operation of clamping the workpiece by two groups of symmetrically contacting the workpiece. Compared with the prior art of clamping the workpiece by a vise, the clamping surface is increased, which can ensure the stability of the workpiece, reduce the clamping force, and prevent the deformation of the workpiece;

[0018] 2. The hinged setting of the V-shaped clamping block and the driving cylinder can eliminate the assembly tolerance between the cylinder baffle and the frame, between the cylinder baffle and the driving cylinder, and between the driving cylinder and the V-shaped clamping block, which causes a deviation between the center of the clamped workpiece and the surface where the cutting part of the saw is located, thereby improving the cutting processing accuracy of the workpiece.

[0025] Furthermore, the cutting device 2 includes a saw 22 and a lifting assembly 21 for driving the saw 22 to rise or fall; wherein the lifting assembly 21 includes a vertical lead screw 211 rotatably connected to the frame 1. As required, both ends of the vertical lead screw 211 are rotatably connected to the frame 1 through bearings; the lead screw portion of the vertical lead screw 211 is matched with a lead screw nut 212, and a connecting frame 213 is provided on one side of the lead screw nut 212 corresponding to the clamping device 3, and the connecting frame 213 is slidably connected to the frame 1 up and down. As required, the frame 1 is provided with a vertical slide rail 215, and the connecting frame 213 is provided with a slider 216 slidably connected to the vertical slide rail 215.

[0026] It should be noted that the saw machine 22 has a saw blade and a motor for driving the saw blade to rotate; if necessary, the saw machine 22 may also have a saw blade protective cover.

[0027] The saw machine 22 is mounted on the connecting frame 213; the frame 1 is equipped with a reduction motor 214 whose output shaft is correspondingly connected to the vertical lead screw 211, which is used to drive the vertical lead screw 211 to rotate clockwise or counterclockwise. The reduction motor 214 can be understood as a combination of a motor and a reducer.

[0028] A clamping device 3 for clamping a workpiece is provided on the top surface of the frame 1. The clamping device 3 includes an S-shaped baffle plate 31 which is provided on the top surface of the frame 1 and symmetrically arranged on both sides of the cutting groove 11. A V-shaped clamping block 32 opposite to the large end of the S-shaped baffle plate 31 is provided; that is, the large end of the S-shaped baffle plate 31 is opposite to the open end of the V-shaped clamping block 32.

[0029] As required, the ends of the two side plates of the eight-shaped baffle plate 31 may be provided with outward bending portions to increase the strength of the side plates.
