Description

Technical Field

[0001] This application relates to the technical field of rock drill machining, and in particular to a tooling for machining the cylinder of a rock drill. Background Technology

[0002] A rock drill is a tool used for drilling holes in rocks. Its working principle is based on compressed air power, with a piston reciprocating through an active valve to achieve drilling. With the continuous advancement of industrial technology, the performance and quality requirements for rock drills are also increasing. As one of its core components, the machining accuracy and efficiency of the rock drill cylinder directly affect the overall performance of the rock drill.

[0003] Currently, due to the irregular shape of rock drill cylinders, traditional clamps use clamps with shapes similar to the cylinder body to hold it. However, this is difficult to flexibly adapt to rock drill cylinders of different specifications and sizes, especially for cylinders with special shapes or irregular dimensions. The clamping effect is poor, easily leading to slight displacement of the cylinder body during processing, which in turn affects processing accuracy and reduces product quality. Moreover, the clamping process of traditional tooling is often cumbersome, requiring a lot of time and manpower, thus reducing production efficiency. Utility Model Content

[0004] In order to improve the applicability of the equipment, facilitate the clamping of the cylinder, and improve production efficiency, this application provides a tooling for machining the cylinder of a rock drill.

[0005] The technical solution for machining a rock drill cylinder body provided in this application is as follows:

[0006] A machining fixture for a rock drill cylinder includes a connecting plate, a lower abutment block, a connecting column, and an upper abutment block. One side of the connecting plate is connected to a drive source. The lower abutment block is connected to the other side of the connecting plate and is used to abut against one side of the product to be processed. One end of the connecting column is connected to the lower abutment block. The upper abutment block is slidably connected to the connecting column, and the sliding direction of the upper abutment block is parallel to the axial direction of the connecting column. The upper abutment block is used to abut against the side of the product to be processed away from the lower abutment block.

[0007] By adopting the above technical solution, the product to be processed is placed on the lower abutment block, and the upper abutment block slides along the axis of the connecting column to approach the lower abutment block and abut against the outer wall of the product to be processed, thereby achieving a fixed connection between the product to be processed and the connecting plate. The connecting plate can be driven to rotate by the drive source, thereby achieving the rotation of the product to be processed, which facilitates the clamping of the product to be processed, improves the applicability of the equipment, and increases production efficiency.

[0008] Preferably, it also includes a connecting nut, and there are two connecting posts. The two connecting posts are symmetrically distributed along a direction perpendicular to the axis of the connecting plate. The upper abutment block is provided with a third connecting hole. The connecting posts are coaxially slidably embedded in the third connecting hole. The connecting nut is threaded to the connecting post and abuts against the surface of the upper abutment block away from the lower abutment block.

[0009] By adopting the above technical solution, the upper abutment block is provided with a third connecting hole, and the connecting column is slidably embedded in the third connecting hole, which guides the sliding of the upper abutment block. The connecting nut abuts against the upper abutment block, so that the upper abutment block and the lower abutment block clamp the product to be processed, thereby improving the reliability of the equipment.

[0010] Preferably, the lower abutment block has a first mounting hole on the side near the upper abutment block. The number of the first mounting holes is the same as the number of connecting posts and they correspond one-to-one. One end of the connecting post is threaded into the first mounting hole.

[0012] Preferably, the lower abutment block has a groove on the side near the upper abutment block, and the side of the groove away from the connecting plate passes through the lower abutment block. The groove is used for embedding the product to be processed.

[0013] By adopting the above technical solution, the groove is used for embedding the product to be processed, which initially limits the product to be processed, reduces the possibility that the upper abutment block will abut the product to be processed or that the product to be processed will detach from the lower abutment block during the processing of the product to be processed, and improves the safety of the equipment.

[0014] Preferably, it also includes an abutment bolt, wherein a third mounting hole is provided at the groove wall, and the abutment bolt is threaded into the third mounting hole and abuts against the outer wall of the product to be processed.

[0015] By adopting the above technical solution, a third mounting hole is set, and the abutment bolt is threaded into the third mounting hole and abuts against the outer wall of the product, reducing the possibility of the product to be processed moving horizontally and improving the reliability of the equipment.

[0016] Preferably, there are several third mounting holes, which are divided into two groups. The two groups of third mounting holes are located on both sides of the groove wall perpendicular to the axis of the connecting plate. The number of abutment bolts is the same as the number of third mounting holes and corresponds one-to-one.

[0017] By adopting the above technical solution, multiple abutment bolts are used to abut the outer wall of the product to achieve a fixed connection between the lower abutment block and the product to be processed, thereby meeting the clamping needs of different products to be processed and improving the applicability of the equipment.

[0018] Preferably, it also includes a connecting bolt, wherein the lower abutment block has a first fixing hole at one end near the connecting plate, the connecting plate has a first connecting hole, and the connecting bolt passes through the first connecting hole and is threadedly connected to the first fixing hole.

[0019] By adopting the above technical solution, the lower abutment block is detachably connected to the connecting plate through connecting bolts, which facilitates the inspection and replacement of the lower abutment block and improves the service life of the equipment.

[0020] Preferably, a first groove is provided on the hole wall at the end of the first connecting hole away from the lower abutment block, and the first groove is used for the head of the connecting bolt to be inserted.

[0021] By adopting the above technical solution, a first groove is provided for the head of the connecting bolt to be inserted, so that the surface of the connecting plate connected to the drive source remains flat, thereby improving the applicability of the equipment.

[0022] Preferably, it also includes a positioning post, one end of which is connected to the end of the lower abutment block near the connecting plate. The connecting plate is provided with a positioning hole for the positioning post to be inserted.

[0023] By adopting the above technical solution, the positioning post is embedded in the positioning hole to achieve the initial positioning of the lower abutment block and the connecting plate, so that the first fixing hole and the first connecting hole are aligned, which facilitates the subsequent fixing of the lower abutment block and the connecting plate and improves the convenience of equipment assembly.

[0024] Preferably, the outer periphery of the positioning post away from the lower abutment block is provided with a first chamfer, which is used to abut against the wall of the positioning hole.

[0025] By adopting the above technical solution, a first chamfer is provided on the outer periphery of the positioning column. The first chamfer plays a guiding role for the positioning column, improving the convenience of equipment assembly.

The connecting plate can be driven to rotate by the drive source, thereby realizing the rotation of the product to be processed, which facilitates the clamping of the product to be processed, improves the applicability of the equipment, and improves production efficiency;

[0028] 2. The groove is used for the product to be processed to be embedded, which initially limits the product to be processed, reduces the possibility that the product to be processed will detach from the lower abutment block during the processing of the product or the upper abutment block, and improves the safety of the equipment.

[0029] 3. A third mounting hole is provided, and the threaded bolt is connected to the third mounting hole and abuts against the outer wall of the product, which reduces the possibility of the product moving horizontally and improves the reliability of the equipment. Attached Figure Description
