[0002] Cone crusher is a kind of raw material crushing equipment used in metallurgy, construction, road construction, chemical and silicate industries. It has the advantages of large crushing ratio, high efficiency, low energy consumption and uniform product particle size.

[0003] The shell of a cone crusher is usually provided with a main shaft hole and a horizontal shaft hole, which are used to install the main shaft of the moving cone and the transmission shaft respectively. When machining the main shaft hole, the shell of the cone crusher needs to be clamped horizontally on the machine tool, while when machining the horizontal shaft hole, the shell of the cone crusher needs to be clamped vertically on the machine tool.

[0004] At present, the supporting tooling structure of common machine tools on the market is relatively simple and can realize basic positioning functions. However, in the processing process, the staff needs to adjust the angle of the cone crusher shell and perform secondary clamping after completing the main shaft hole processing before processing the horizontal shaft hole. Position measurement and verticality measurement are required during the secondary clamping process. The workflow is cumbersome, and there will inevitably be errors in the secondary clamping, which affects the processing accuracy of the horizontal shaft hole. Utility Model Content

[0010] The beneficial effects of using the utility model are:

[0011] This solution provides a cone crusher shaft hole processing tool that can change its shape. The processing direction can be adjusted by rotating the tool obliquely. The main shaft hole and the horizontal shaft hole can be processed without secondary clamping, and the verticality is limited by the rotation angle of the tool.

[0024] Specifically, the rotating shaft assembly 4 specifically includes a rotating shaft, a damping kit and a plane bearing, wherein the damping kit is used to slow down the rotation speed of the lower bracket 1 and the upper bracket 2, slow down the amplitude of the upper bracket 2 during the tooling transformation process, and prevent the upper bracket 2 and the workpiece from directly tipping over under the action of gravity and swinging under the action of inertia after the locking mechanism is released;

[0025] According to the equipment scale and production efficiency requirements, a motor can be configured on the rotating shaft.

[0026] Cone crusher shells are usually processed using gantry-type machining centers or track-type machining equipment;

[0027] When a gantry type machining center is used, since the gantry type machining center has a large Z-axis machining volume, the lower bracket 1 can be directly fixed on the workbench of the machining center by bolts;

[0028] When using track-type processing equipment, the maximum Z-axis processing capacity of the processing equipment must be considered;

[0033] The upper end surface of the upper bracket 2 is integrally formed with an inner edge 202, and the outer diameter of the inner edge 202 matches the inner diameter of the clamping plate 3. The upper end surface of the upper bracket 2 is evenly provided with a plurality of positioning grooves 201, and the position and number of the positioning grooves 201 correspond to the position and number of the clamping jaw assembly seat 301. The clamping jaw assembly seat 3 is sleeved on the inner edge 202, and the clamping jaw assembly seat 301 is embedded in the positioning groove 201. A plurality of first positioning holes 203 and a plurality of clamping jaw assembly seats 301 are respectively provided on the side walls of the inner edge 202 and the side walls of the clamping jaw assembly seat 301, and the positions of the first positioning holes 203 and the clamping jaw assembly seat 301 correspond one to one, and bolts are assembled at the first positioning holes 203 and the clamping jaw assembly seat 301.

[0034] A plurality of fixing holes 304 are provided on the surface of the chuck 3, and process holes or mounting holes are provided on the workpiece, and the positions of the fixing holes 304 match those of the process holes or mounting holes;

[0035] When the workpiece is large and it is difficult to maintain the stability of the clamping state only by the clamping jaws, the workpiece is further fixed by bolts.

The two pin holes 501 are coaxially distributed, and the locking pin 5 is inserted into the two pin holes 501 at the same time to achieve the locking effect of the lower bracket 1 and the upper bracket 2.
