Description

Technical Field

[0001] The utility model belongs to the technical field of equipment gear grinding, and particularly relates to a grinding device with good positioning effect. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. When machining gears, they are generally manufactured by forging, cutting, etc. However, during the re-processing process, since the shaft hole will have burrs on the gear surface and the bottom shaft hole position after stamping, the existing technology mostly uses a grinder to grind it.

[0003] A grinder is usually composed of a frame, a control system, a moving component and a grinding component. The moving component is used to fix and move the workpiece to be processed, and the grinding component is used to perform surface treatment on the workpiece.

[0004] However, when existing mobile components clamp gears, they generally use clamping claws for positioning without professional clamping and fixing equipment, which causes the gears to easily deviate in angle during grinding, greatly increasing the product rejection rate.

[0005] In view of this, how to solve the defects existing in the above technical solutions has become one of the problems to be solved urgently in the field of gear grinding technology. Utility Model Content

[0006] In view of the problems existing in the background technology, the purpose of the utility model is to overcome the shortcomings of the prior art and provide a grinding device with good positioning effect, so as to solve the problem that the existing mobile components generally use clamps for positioning when clamping gears, and there is no professional clamping and fixing equipment, which leads to the gears being prone to angular deviation during grinding, greatly increasing the product rejection rate.

[0007] The utility model is implemented through the following technical scheme. The utility model discloses a grinding device with good positioning effect, including a grinder, a placement table and a sliding clamping device. The placement table is arranged below the grinding head of the grinder and is used to position the gear. The grinder can be a grinder commonly used on the market. The sliding clamping device is arranged on both sides of the placement table, and the gear on the placement table is clamped and fixed by the sliding clamping device; the sliding clamping device includes a slide rail assembly, and the slide rail assembly is provided with a clamping device in a sliding connection manner.

[0008] Optionally, the slide rail assembly is installed with a guide rail, and a moving part is installed on the guide rail by a sliding connection, a supporting part is installed on the moving part, a mounting plate is welded on the supporting part, and a clamping assembly is installed on the mounting plate toward one end of the guide rail.

[0009] Optionally, the clamping assembly includes a hydraulic cylinder, the protruding end of the hydraulic cylinder passes through the mounting plate and is installed with a clamping sleeve in a fixed connection manner, and a clamping piece is provided on the clamping sleeve.

[0010] Optionally, the clamping member is arranged in an arc shape on a side away from the clamping sleeve, and contacts with a tooth groove wall between two adjacent teeth.

[0011] Optionally, a positioning piece is installed on the placement table, a positioning column is provided at the middle part of the positioning piece, and at least two groups of clamping fixing pieces are provided on the side of the placement table facing the positioning column.

[0012] Optionally, the clamping fixture includes a mounting frame, the mounting frame is disposed on the placement table, a sliding table is mounted on the top of the mounting frame in a sliding connection manner, and the position is fixed by fasteners.

[0013] Optionally, an elastic clamp is provided on the slide, and the elastic clamp includes two groups of arc plates, and a connecting plate is provided between the two groups of arc plates, and the connecting plate is integrated with the arc plates.

[0014] Optionally, the arc-shaped plate is made of elastic material.

[0015] Optionally, a gasket is glued and installed on the arc-shaped plate on the side facing the gear to be clamped.

[0016] In summary, the beneficial effects of the utility model are:

[0017] 1. The extended end of the hydraulic cylinder of the utility model extends out, thereby driving the clamping piece to be clamped into the tooth groove walls of two adjacent tooth stoppers at the corresponding position of the gear, so that the clamping piece is engaged with the gear, and the gear is clamped by two sets of relatively arranged clamping pieces to prevent the gear from being offset during the grinding process.

[0018] 2. The utility model adds a clamping fixture on the placement table. Before processing the gear, firstly, the two sets of arc plates of the elastic clamp are pried apart by force, and then the two sets of arc plates are used to clamp and fix the teeth of the gear. At this time, since a gasket is glued and installed on the arc plate on the side of the gear to be clamped, it is prevented that the arc plate is used to clamp the gear. The gear is prevented from being damaged due to excessive elastic force. BRIEF DESCRIPTION OF THE DRAWINGS
