Description

Technical Field

[0001] This utility model is a tool tip arc surface grinding machine, belonging to the field of tool processing technology. Background Technology

[0002] The grinding precision of the tool tip arc surface directly affects the cutting performance, service life, and surface quality of the machined workpiece. This is especially true in precision machining and tool repair, where the consistency and smoothness of the tool tip arc surface are of paramount importance. However, existing tool tip arc surface grinding equipment suffers from poorly designed tool fixing mechanisms, often employing unidirectional clamping. This results in uneven clamping force and poor stability, leading to tool displacement and wobbling during grinding, causing grinding deviations. Furthermore, the angle adjustment flexibility is insufficient, making it difficult to adapt to the grinding needs of different tool tip models and arc requirements. This poor versatility reduces grinding precision and work efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a blade tip arc surface grinding machine.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A blade tip arc surface grinding machine includes a base, a support is provided on the top of the base, a shaft is vertically rotatably connected to one side of the top of the support, a horizontally arranged rotating shaft is rotatably connected to the top of the shaft, and a movable rod is provided on the rotating shaft in a cross-shaped movable through connection. A fixing mechanism is provided on the top of the base and on the side away from the shaft. The fixing mechanism is used to clamp and fix the tool. A grinding block is provided on the movable rod at the tool. The grinding block is connected to the movable rod through a connecting mechanism. A ball is provided on the end of the movable rod away from the rotating shaft.

[0005] Preferably, the fixing mechanism includes a vertically arranged mounting plate. One side of the mounting plate is provided with a symmetrically arranged crossbar 1 and crossbar 2. The side of the crossbar 1 and crossbar 2 closest to the mounting plate is provided with symmetrically arranged connecting parts. The other end of the connecting parts is movably connected to the mounting plate with a mounting seat. The side of the crossbar 1 and crossbar 2 furthest from the mounting plate is provided with symmetrically arranged L-shaped support rods. The other end of the L-shaped support rods is provided with a clamping plate that abuts against the outer wall of the tool.

[0006] Preferably, a connecting rod is provided between each pair of the first crossbars and between each pair of the second crossbars, and the connecting member is provided with a pin that is movably connected to the mounting base.

[0007] Preferably, a cylinder for driving the connector to rotate is rotatably connected to the mounting base.

[0008] Preferably, the mounting plate has a fixed shaft on the other side, and the support has a drive mechanism for driving the fixed shaft to rotate.

[0009] Preferably, the fixed shaft is connected to the support via a bearing housing.

[0010] Preferably, the connecting mechanism includes a bracket, which is connected to the grinding block by a bolt, and the top of the bracket is symmetrically provided with sleeves that are movably fitted onto the movable rod.

[0011] Preferably, the sleeve is provided with two bolts for connecting the movable rod.

[0012] The beneficial effects of this utility model are: With the setting of the fixed mechanism, the cylinder drives the connecting part to rotate around the pivot pin, thereby driving the crossbar one and crossbar two to move synchronously. This allows the crossbar one and crossbar two to drive the clamping plate through the L-shaped support rod to achieve symmetrical and uniform clamping of the tool. The clamping force is stable and adjustable, effectively preventing the tool from shifting or shaking during grinding, and providing a foundation for high-precision grinding. The vertical rotation of the shaft, the horizontal rotation of the pivot, and the cross-shaped movement of the movable rod form a multi-dimensional adjustment structure that can precisely adapt to the tool tip grinding requirements of different types of tools and different curvature requirements, greatly improving the equipment's versatility.
