Description

Technical Field

[0001] The present invention relates to the technical field of gear seat processing, and more specifically, to a gear seat processing tool and a gear seat processing method. Background Art

[0002] The tooth seat is an indispensable component of the coal mining machine. It is installed on the drum of the coal mining machine. The tooth seat is provided with an inner hole for the installation of the pick mounting sleeve. The pick mounting sleeve is a kind of mounting sleeve. A mounting surface is provided on one side of the tooth seat. The mounting surface is an inclined surface, which is parallel to the axis of the inner hole. The mounting surface is the contact surface between the tooth seat and the drum. The tooth seat is installed on the drum through the mounting surface.

[0003] like Figure 1 It is a gear seat, including a connecting portion 11 and a mounting portion 12, wherein a mounting surface 121 is located on the connecting portion 11, and an inner hole 111 is located in the mounting portion 12. Since the outer side of the mounting portion 12 of the gear seat 1 is an arc surface structure, it is not easy to fix the gear seat 1 when processing the inner hole 111 and the mounting surface 121, which affects the processing efficiency and processing accuracy of the gear seat 1. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a gear seat processing tool and a gear seat processing method, which first clamps the gear seat through a clamping plate when processing the gear seat, and then fixes it, which facilitates the fixation of the gear seat and improves the processing efficiency and processing accuracy.

[0006] and a fixing assembly, which is used to fix the clamping assembly clamping the gear holder on the wire cutting workbench, wherein when the gear holder is fixed on the wire cutting workbench, the mounting surface of the gear holder is in a vertical position;

[0007] The clamping assembly comprises two clamping plates, and the two clamping plates clamp the gear seat between the two clamping plates.

[0008] By adopting the above technical scheme, when processing the inner hole, the tooth seat is first clamped by two clamping plates, and then the two clamping plates are fixed, thereby realizing the fixation of the tooth seat, so that the tooth seat can be firmly fixed during the process of processing the inner hole, thereby improving the processing efficiency and processing accuracy; in the process of processing the mounting surface, the two clamping plates and the tooth seat are fixed by the fixing assembly, and the mounting surface is processed by wire cutting; since the material of the tooth seat is mostly 40CrNiMo, which has high strength and toughness, when it is processed by grinding, the processing difficulty is great and the processing speed is slow. Processing by wire cutting reduces the processing difficulty and increases the processing speed, thereby improving the processing efficiency.

[0009] The present invention is further configured such that the two clamping plates clamp the mounting portion of the gear holder between the two clamping plates.

[0010] By adopting the above technical solution, the mounting portion is clamped between the two clamping plates, so that the connecting portion extends out from between the two clamping plates, thereby preventing the clamping plates from being damaged during the wire cutting process.

[0011] The present invention is further configured such that when the two clamping plates clamp the mounting portion, the sides of the two clamping plates close to each other fit with the arcuate surfaces of the mounting portion close to both sides of the two clamping plates.

[0012] The present invention is further configured as follows: the clamping assembly also includes a connecting plate, and when the two clamping plates clamp the gear holder, the clamping plate can be fixed on the connecting plate.

[0013] By adopting the above technical solution, the clamping plate is fixed on the connecting plate, so that the clamping plate can easily maintain the state of clamping the pool seat.

[0014] The present invention is further configured as follows: a guide rod is provided on the connecting plate, and the two clamping plates move in directions of approaching and moving away from each other to achieve clamping and loosening of the gear seat;

[0015] The guide rod is inserted into the two clamping plates to guide the moving direction of the clamping plates.

[0016] The present invention is further configured as follows: the fixing assembly comprises a quick clamp, which is provided with at least one quick clamp, and the quick clamp is used to press the clamping assembly onto the wire cutting workbench.

[0017] The present invention is further configured as follows: the fixing assembly further comprises a base, which is detachably connected to the wire cutting workbench, and the quick clamp presses the clamping assembly onto the top of the base;

[0018] And a support plate, which is fixedly connected to the base and is used to support the quick clamp.

[0019] The present invention is further configured as follows: a positioning bar is arranged on the top of the base, two positioning bars are arranged under each quick clamp, and the clamping assembly clamped under the quick clamp is positioned by the two positioning bars.

[0020] Another object of the present invention is to provide a method for machining a tooth seat, comprising the following steps:

[0021] Clamp the gear holder to be processed: clamp the gear holder between two clamping plates;

[0022] Drilling: Fix the two clamping plates and drill holes in the gear holder clamped between the two clamping plates;

[0023] Finishing: Fix the two clamping plates and finish the inner hole of the gear seat until the inner hole size reaches the designed size;

[0024] Fixing the clamping assembly: fix the tooth holder on the wire cutting workbench through the fixing assembly, and make the mounting surface in a vertical state at this time;

[0025] Wire cutting: The mounting surface of the gear seat is processed by wire cutting.

[0026] The present invention is further configured such that when performing wire cutting processing, the diameter of the metal wire is selected to be 0.15 mm.

[0027] In summary, the present invention has the following beneficial effects compared with the prior art: when the present invention performs inner hole processing, the tooth seat is first clamped by two clamping plates, and then the two clamping plates are fixed, thereby realizing the fixation of the tooth seat, so that the tooth seat can be firmly fixed during the inner hole processing, thereby improving the processing efficiency and processing accuracy; in the process of mounting surface processing, the two clamping plates and the tooth seat are fixed by a fixing assembly, and the mounting surface is processed by wire cutting; since the material of the tooth seat is mostly 40CrNiMo, which has high strength and toughness, when it is processed by grinding, the processing difficulty is great and the processing speed is slow. Processing by wire cutting reduces the processing difficulty and increases the processing speed, thereby improving the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
