[0002] At present, during the deep processing of grinding the internal hole, most of them use the chuck clamping method to singly process and grind the internal hole. The advantage of such processing is that the accuracy can be guaranteed, but the disadvantage is low efficiency, which is suitable for processing small batches of products. For large batches of products, the production and processing efficiency is low and cannot meet the production needs. At the same time, the chuck clamping and dial indicator alignment have high technical level requirements for operators.

[0003] To solve the above problems, the prior art patent (CN 207746879U) discloses an internal hole fixture for petroleum bushing processing, including a sleeve fixture and an end cover. The sleeve fixture is provided with a sleeve cavity, and the sleeve cavity is a cylindrical cavity. At the left end of the sleeve cavity, there is also a sleeve through hole coaxial with the sleeve cavity. The cross-sectional diameter of the sleeve through hole is smaller than the diameter of the sleeve cavity. The outer edge of the right part of the sleeve fixture is provided with an external thread. The right end of the end cover is provided with a central hole for the internal grinding head to pass through, and the left end is provided with a circular cavity coaxial with the central hole. The inner wall of the circular cavity is provided with an internal thread matching the external thread of the fixture sleeve. The left end of the sleeve fixture is clamped by a three-jaw chuck. The structure of the utility model is simple, safe and reliable, and greatly improves the production efficiency after use.

[0004] However, in the above prior art, after the internal hole grinding of the bushing is completed, grinding debris will remain in the bushing, and the inside of the bushing needs to be cleaned separately after the bushing is taken out. Summary of the Utility Model

The foregoing solution solves the problem that after the inner hole grinding of the bushing is completed, grinding debris remains in the bushing, and the inside of the bushing needs to be cleaned separately after the bushing is taken out.

[0021] For this specific embodiment, the chuck base 102 is fixedly connected to the operating table 101 and is located above the operating table 101. The three-jaw chuck 103 is fixedly connected to the chuck base 102 and is located above the chuck base 102. The sleeve fixture 104 is detachably connected to the three-jaw chuck 103 and is located outside the three-jaw chuck 103. The cleaning component includes a support member, an electric cylinder 105, a connecting sleeve 106, a driving member, an access port 107, an air pipe 108 and a plurality of inclined blowing pipes 109. The support member is fixedly connected to the operating table 101 and is located outside the chuck base 102. The electric cylinder 105 is detachably connected to the support member and is located above the support member. The connecting sleeve 106 is fixedly connected to the output end of the electric cylinder 105 and is located inside the three-jaw chuck 103. The driving member is detachably connected to the access port 107 and is located outside the electric cylinder 105. The access port 107 is fixedly connected to the air pipe 108 and is located outside the connecting sleeve 106. The air pipe 108 is fixedly connected to the connecting sleeve 106 and is located inside the connecting sleeve 106. A plurality of the inclined blowing pipes 109 are fixedly connected to the air pipe 108 and are located inside the sleeve fixture 104, and the inclined blowing pipes 109 penetrate through the connecting sleeve 106. The chuck base 102 fixes the three-jaw chuck 103 above the operating table 101. The sleeve fixture 104 is fixed inside the three-jaw chuck 103. The electric cylinder 105 is fixed above the support member. The driving member is connected to the access port 107. After the grinding operation of the bushing in the sleeve fixture 104 is completed, the electric cylinder 105 pushes the connecting sleeve 106 to move outward. The air pipe 108 conveys high-pressure air to the inclined blowing pipes 109. The inclined blowing pipes 109 are arranged at an angle of 30 degrees, which is convenient for blowing the grinding debris inside the sleeve fixture 104 to the outside. In this way, the problem that grinding debris remains in the bushing after the inner hole grinding operation of the bushing can be effectively solved.

[0022] Among them, the fixed seat 110 is fixedly connected to the workbench 101 and is located outside the chuck base 102. The L-shaped plate 111 is detachably connected to the fixed seat 110 and is located outside the electric cylinder 105. The fixed seat 110 is fixed above the workbench 101. The L-shaped plate 111 is fixed to the fixed seat 110 by bolts and is fixed to the electric cylinder 105 by bolts, so as to fix the electric cylinder 105 above the fixed seat 110.

[0023] Secondly, the high-pressure air blowing pump 112 is fixedly connected to the workbench 101 and is located outside the fixed seat 110. The connecting pipe 113 is detachably connected to the access port 107 and is located outside the access port 107. The connecting pipe is a rubber hose and can pull the pipe according to the electric cylinder 105. When the high-pressure air blowing pump 112 operates, high-pressure air is conveyed into the air pipe 108 through the connecting pipe 113.

[0024] At the same time, the barrier cover 114 is fixedly connected to the workbench 101 and is located above the collection box 115. The collection box 115 is slidably connected to the workbench 101 and is located below the sleeve fixture 104. The handle 116 is fixedly connected to the collection box 115 and is located outside the collection box 115. The barrier cover 114 is used to block the debris blown out of the sleeve fixture 104 and guide the blocked debris into the collection box 115 below. The handle 116 is used to install and remove the collection box 115.

[0025] In addition, the workbench 101 has a placement groove 117 adapted to the collection box 115, and the collection box 115 is slidably placed in the placement groove 117, which is convenient for cleaning the collection box 115.

[0026] When using an internal hole grinding fixture for bushing processing according to this embodiment, by providing the chuck base 102, the three-jaw chuck 103, the sleeve fixture 104 and the cleaning assembly, during specific use, the chuck base 102 fixes the three-jaw chuck 103 above the workbench 101, the sleeve fixture 104 is fixed inside the three-jaw chuck 103, the electric cylinder 105 is fixed above the fixed seat 110, the connecting pipe 113 is connected to the access port 107. When the grinding operation of the bushing inside the sleeve fixture 104 is completed, the electric cylinder 105 pushes the connecting sleeve 106 to move outward, the high-pressure air blowing pump 112 operates, and high-pressure air is conveyed through the connecting pipe 113 into the air pipe 108. The air pipe 108 conveys the high-pressure air to the inclined blowing pipe 109, and due to the inclined setting of the inclined blowing pipe 109, the grinding debris inside the sleeve fixture 104 is blown outward. The barrier cover 114 blocks the debris blown out from inside the sleeve fixture 104 and guides the blocked debris into the collection box 115 below. In this way, the grinding debris inside the bushing can be conveniently cleaned, effectively improving the operation efficiency and facilitating the subsequent processing operation of the bushing.
