Background

On a numerical control milling machine or a machining center, the clamping and machining method of the gear groove mainly comprises the following steps: 1. using the adhesive A/B to paste the workpiece on a workbench for split processing; 2. clamping by using bench clamp and cushion block, installing three bench clamps on a workbench, separating and then machining 3. Installing six three-jaw self-centering chucks on the workbench for machining, wherein the common defects of the three methods are as follows: the machining efficiency is low, the manual labor intensity is high, and the time for manually installing and dismantling the parts is long. The advantages are that: the method 1 includes the steps that a plurality of parts are machined at one time, centering in each part is needed, glue removal is needed after machining is finished, and centering in each installation is needed; the method 2 and 3 have the advantages that after one-time clamping alignment, alignment is not needed in the subsequent processing, and the processing can be performed after clamping, but the processing efficiency is low.

Disclosure of utility model

The utility model aims to provide a special template clamp for a gear groove, so as to solve the problems in the prior art. The technical aim of the utility model is realized by the following technical scheme that the special template clamp for the gear groove comprises a front template and a back template, a workpiece is accurately positioned through a positioning hole or a positioning block on the template, and then the workpiece is pressed and fastened on the template through a bolt and a gasket to process the gear groove. The front template is provided with 20 positioning holes matched with the convex cylinders on the gears, and M6 threads with the depth of 15mm are arranged in the positioning holes. The reverse side template is provided with 20X4 positioning blocks according to the gear groove, 20 groups of positioning blocks are arranged in one group of each 4 positioning blocks, and M6 threads with the depth of 15mm are still arranged in the middle of each 4 positioning blocks. M6 threads with a depth of 15mm are still arranged in the middle of every 4 positioning blocks.

In summary, the utility model has the following beneficial effects:

Through the arrangement of a plurality of positioning holes or positioning blocks, the purpose of quick positioning can be achieved. Because the position of the positioning hole or the positioning block on the template is fixed, the selected number of the workpiece coordinate systems is increased to 48 by adopting an auxiliary coordinate system G54.1Pn of a machine tool system, wherein the value of n is 1-48, the far-exceeding standard coordinate systems are many, the machining requirements of multiple workpieces are met, the setting of the additional workpiece coordinate systems is the same as that of the standard workpiece coordinate systems, the measured values are sequentially input into the system, 20 parts can be machined by one-time clamping, more than three times of the original clamping can be machined, and then the coordinate systems are directly called without dividing the machining, so that the machining efficiency is greatly improved.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Example 1:

The special template clamp for the gear groove is characterized in that the template is divided into a front side and a back side, and two processing templates are manufactured as shown in fig. 3 and 4, wherein the sizes of the two processing templates are 240mmX900mmX20mm. The size of the positioning hole of the front template in figure 3 is set according to the size of the convex cylinder of the gear, 20 positioning holes matched with the convex cylinder are formed in the template, and M6 threads with the depth of 15mm are processed in the positioning holes. In the reverse template figure 4, 20X4 positioning blocks are arranged according to the grooves of the gears, and M6 threads with the depth of 15mm are still processed in the middle of each 4 positioning blocks. And (3) placing the set template on a workbench of a machining center or a numerical control milling machine, aligning, pressing one template by 4 pressing plates at each angle, and fixing the template on the workbench. Installing, machining and disassembling a workpiece; 1. positioning 20 gear pieces in sequence by using positioning holes and convex cylinders on the gears, and fixing the workpiece by using bolts and gaskets through internal threads on the templates; 2. then adopting an auxiliary coordinate system G54.1Pn of the Fanac system, wherein the value of n is 1-48. The selection number of the workpiece coordinate systems is increased to 48, which is much more than that of the standard coordinate system, and the requirement of the coordinate system in the middle is met. The setting of the additional object coordinate system is the same as the setting of the standard object coordinate system, and the measured values are sequentially input into the system. The clamping device can process 20 parts at one time, which is more than three times of the original clamping device, and then the coordinate system is directly called without dividing the machining process, so that the machining efficiency is greatly improved. 3. Directly changing the original numerical control program for machining the reverse surface into a subprogram, and adopting an auxiliary coordinate system to write a main program for machining. 4. And unloading the processed part, mounting the part on another processing center, positioning the part by using a positioning block, and connecting and compacting the part by using a bolt. 5. The setting of the front additional object coordinate system is the same as the setting of the back object coordinate system, and will not be described in detail. 6. Directly changing the original numerical control program for machining the front surface into a subprogram, and adopting an auxiliary coordinate system to write a main program for machining. 7. And after the processing is finished, the part is disassembled. 8. After the steps are finished, the machining of 20 parts can be finished by once clamping according to the machining process of the parts, and the whole process is simple, convenient and quick and is an efficient machining method.
