Description

Technical Field

[0001] The invention relates to the technical field of elevator wheel processing, and in particular to an elevator wheel surface finishing device. Background Art

[0002] In traditional traction wheel processing clamping mechanisms, a single fixing mode is mostly used, which is difficult to adapt to different types of traction wheels, resulting in poor equipment versatility. When facing the same type of traction wheels, the size and position distribution of the fixing holes on the surface of the traction wheel are different, resulting in incompatible clamping and unstable grinding process.

[0003] Comparative document CN114770254B discloses an elevator wheel surface finishing device and process, including a support frame, a fixed plate, a rotating table, a quick locking device and a grinding part; the present invention solves the main problems in the current elevator traction wheel processing process, that is, after the traction wheel is turned, there will be metal residues such as burrs and sharp corners on the edge of the traction wheel, which will have a safety impact on the operator, and will cut the rope and affect the service life of the rope; and the traction wheel is often fixed by moving the inner diameter chuck outward to contact the inner wall of the traction disk to fix the traction wheel. This method limits the freedom of the traction wheel to a small extent, lacks stability, and the traction wheel is prone to warping and offset during the clamping process, and the parallelism error is large after the secondary clamping.

[0004] During the actual use of the above-mentioned device, due to the different types of traction wheels and different clamping methods, the device is only suitable for a single type of traction wheel and is not suitable for different types of traction wheels. In addition, the sizes and positions of the fixing holes on the surface of the traction wheel are distributed differently, resulting in incompatible clamping and unstable grinding process. Summary of the invention

[0005] In view of the technical problems existing in the prior art, the present invention provides an elevator wheel surface finishing device, which effectively clamps different types of traction wheels through clamping component 2, clamping component 1 and a fixing rod of a clamping assembly, so that different types of traction wheels can be polished, thereby improving the scope of application and stably achieving the technical effect of finishing and polishing the wheel groove of the traction wheel.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: an elevator wheel surface finishing device, comprising a base and a traction wheel, wherein the traction wheel is divided into a traction wheel A with an A column and an A ring and a traction wheel B with a B ring, the surface of the B ring is circumferentially provided with fixing holes, a herringbone groove is opened on the upper part of the base, and two main gears and a secondary gear round seat that are meshed with each other are rotatably connected on the base, and the main gear is driven by a motor; the base is also provided with three groups of clamping assemblies, the clamping assemblies include a hydraulic cylinder driving a connecting block, a clamping piece 2 and a clamping piece 1 for clamping the traction wheel A are provided on the connecting block, a clamping piece 3, a telescopic rod and a fixing rod are provided on the clamping piece 1 for clamping the traction wheel B, and a grinding assembly for grinding the wheel groove of the traction wheel is provided on the secondary gear round seat; A circular through-hole groove is formed in the middle of the auxiliary gear circular seat, and the herringbone groove is located in the circular through-hole groove. Three sets of clamping components are arranged in the herringbone groove.

An elastic member is provided on the surface of the second clamping piece that contacts the A-pillar for clamping and adapting to the arc of the A-pillar. The third clamping piece is rotatably connected to the first clamping piece. The telescopic rod is slidably connected inside the third clamping piece, and the fixed rod is slidably connected to one end of the telescopic rod. The fixed rod is used to be fixed in the fixing hole on the surface of the B-ring to prevent the traction wheel B from rotating during the grinding process of the grinding component. The grinding component includes a first shell and a second shell that are symmetrically arranged. A first grinding block is provided on one end surface of the first shell facing the circular through-hole groove of the auxiliary gear circular seat, and a second grinding block is provided on the end surface of the second shell opposite to the first grinding block.

One end of the connecting belt is fixed to the other second clamping piece, and the other end is clamped in the inverted T-shaped groove of the other second clamping piece. A bladder one with an inflation port is also fixed on the connecting belt. By passing the connecting belt around the A-pillar and inflating and squeezing the bladder one, the upward offset of the traction wheel A is prevented.

[0008] Further, an elastic grinding block with a U-shaped groove is connected to one end of the first grinding block facing the circular through-hole groove of the auxiliary gear circular seat for guiding large particle waste chips to pass through.
