Description

Technical Field

[0001] The invention belongs to the technical field of tappet processing, in particular to a special machine tool for tappet precision digging. Background Art

[0002] The valve tappet is an important component in the engine's valve train. During engine operation, the flexibility of its movement and rotation will affect the engine's performance to a certain extent. Common valve tappets include straight, mushroom, waisted or other special shapes. Each valve tappet has at least one oil guide hole and oil return hole. For the processing of the tappet, it is usually necessary to drill a hole on the top and use a precision drilling machine to open a blind hole on the top of the tappet.

[0003] The special machine tool for precision digging of the tappet in the prior art, during use, for the continuous processing of the tappet, usually adopts a fixture for positioning and clamping, and cooperates with the lowered rotating tool to perform top precision digging and drilling. Actually, after the blind hole drilling process, there is a certain degree of roughness inside the blind hole, and it is necessary to cooperate with the grinding component again, and move to the top of the tappet for positioning and grinding. Moreover, after the actual grinding process, the processed tappet needs to be taken out of the positioning fixture, which is disturbed by the two sets of drilling and grinding processes. Actually, from the perspective of the entire process of positioning, drilling, grinding and unloading, each step is isolated from each other and implemented separately. The operation of each step of the entire processing process is cumbersome, and the overall processing efficiency is low. In addition, during the top-down grinding process of the blind hole, debris continues to remain in the blind hole and is difficult to escape.

[0052] By utilizing the loading assembly 7, automatic correction and preliminary positioning of the input tappet material can be achieved. The inclination angle and width of the feed frame 72 are adapted to the tappet, so that the tappet material automatically maintains a vertical positioning state when it slides and falls. The linkage compression assembly 8 cooperates with the downward extrusion block 9, and utilizes hydraulic oil to transmit pressure. When the positioning clamping part 6 descends, the tappet material is automatically pushed upward simultaneously to complete rapid positioning and assembly, thereby greatly improving the continuous processing efficiency.

[0053] Embodiment 2: When fine drilling is performed, the tappet material to be processed is put in along the feed frame 72 on the side of the loading assembly 7, and the columnar tappet material slides along the inclined feed frame 72 and is automatically inserted into the interior of the loading barrel 71. When the tappet material needs to be clamped, the electric push rod 2 is started and drives the support plate 3 and the positioning clamping part 6 to move downward synchronously, so that the positioning clamping part 6 is gradually inserted into the interior of the loading barrel 71. At the same time, the support plate 3 drives the extrusion block 9 at the bottom to be inserted into the linkage compression assembly 8. As the extrusion block 9 moves downward synchronously, the extrusion block 9 presses down the push plate 83 and the spring three 84. The hydraulic oil inside the storage frame 81 is further compressed into the interior of the loading barrel 71 through the intermediate sleeve 82, and simultaneously pushes the movable plug 74 and the push rod 75 upward, pushing the columnar push rod material that falls into the loading barrel 71 upward into the guide sleeve 73, and further vertically corrected along the reduction cavity in the guide sleeve 73, and cooperates with the downward sleeve 61, and then the pressurized air in the distributed air supply assembly 10 is input into the positioning clamping part 6 to automatically clamp and fix the push rod material, completing the automatic positioning, loading and clamping, and then starting the electric push rod 2 to move upward for subsequent fine digging and drilling processing.

[0054] Firstly, by utilizing the additional feeding assembly 7 and linkage compression assembly 8, and utilizing the positioning clamping part 6 controlled by the up and down movement, when the tappet raw material is put in, in cooperation with the preliminary positioning of the feeding assembly 7, the downward-moving support plate 3 is utilized to drive the extrusion block 9 to compress the hydraulic oil in the linkage compression assembly 8 during the downward movement, thereby quickly pushing the tappet raw material in the feeding assembly 7 to be automatically positioned and sleeved in the synchronously downward-moving positioning clamping part 6, completing the rapid matching and insertion, and utilizing the distributed air supply assembly 10 to complete the clamping and fixing, realizing automatic positioning and clamping, and the positioning and fixing of the tappet raw material in the actual fine excavation process is efficient and fast, and the drilling, grinding, and automatic blanking processes that can be completed by cooperating with the up and down movement further realize the automatic feeding step, so that the entire fine excavation process has a high degree of continuous automation, can continuously move and complete the processing, and can be efficiently operated and processed from the beginning to the end of the fine excavation, and the fine excavation processing of the blind hole at the top of the tappet is realized, which has the effect of efficient production and processing, high actual production efficiency, and good application prospects.

[0055] The working principle and use process of the present invention are as follows: when in use, the columnar tappet to be processed is placed inside the positioning clamping part 6, and the distributed air supply component 10 is started. As the air pump 101 outputs gas, the No. 1 valve 102 guides the gas to the guide cover 104, so that the pressurized air is input into the assembly component 5 through the connecting arm 52, and is input into the internal cavity 62 of the positioning clamping part 6 through the connecting ring 51. The pressurized air acts on the clamping block 63, and the surrounding clamping blocks 63 clamp and fix the inserted columnar tappet raw material. Then the electric push rod 2 is started to push the support plate 3 and the mounting curved plate 4 to move upward, so that the positioning clamping part 6 drives the internally clamped and fixed tappet raw material to move upward, so that the connecting sleeve 12 moves along the sliding sleeve in the air guide component 13. The slot 132 moves upward to start the drilling mechanism 14. As the tool in the drilling mechanism 14 rotates, the columnar tappet material moving upward contacts and squeezes the rotating tool to complete the top blind hole drilling. When the specified drilling depth is reached, the connecting sleeve 12 fixed at the end of the support plate 3 is located at the No. 2 guide hole 134 and connected to the No. 2 guide hole 134. The air pump 101 is kept started, and the No. 1 valve 102 closes the guide cover 104 and opens the connection with the intermediate pipe 105, and the No. 2 valve 103 is connected to the connecting sleeve 12 separately, so that the pressurized air is input into the jet pipe 135 along the connecting sleeve 12 and the No. 2 guide hole 134, so that the jet pipe 135 is purged toward the gap between the holes on the top of the tappet, and the internal cutting fluid and debris are purged out. Rod 2 moves and drives the positioning clamping part 6 and the tappet at the end of drilling to move downward. After moving away from the tool, valve No. 2 moves, closes the connecting sleeve 12, and opens the connection with the pushing component 11. The air pump 101 inputs pressurized air into the pushing component 11, and drives the curved rod 113 to move horizontally and contact with the limit plate fixed on one side of the support plate 3, and at the same time drives the tooth plate 112 to move horizontally and rotate the meshing gear 53, thereby rotating the assembly component 5, so that the top of the clamped tappet is tilted downward, and the electric push rod 2 drives the inclined tappet to move downward to the oblique upper part of the grinding component 15 and is located on the upward inclined extension line of the inclined cylinder 151. At this time, the connecting sleeve 12 is connected with the No. 1 guide hole 133, which makes the No. 2 valve 103 move again, closing and pushing. After the assembly 11 is turned on, the opening of the connecting sleeve 12 is opened, so that the pressurized air is input into the connecting sleeve 12 again, and then input into the inclined cylinder 2 152 through the No. 1 guide hole 133 and the side pipe 156, and the internal air pressure of the inclined cylinder 2 152 is increased, and the curved pull rod 154 is pushed to move horizontally, the spring 5 155 is stretched, and the grinding part 153 is driven to move up along the inclined cylinder 1 151 and gradually insert into the inclined blind hole of the tappet, the grinding part 153 is started, and the grinding block rotates and grinds in the blind hole to complete the grinding process, and then the grinding part 153 is reset, and the electric push rod 2 is moved down again, and the inclined tappet is kept moving down, so that the tappet moves down to the upper inclined extension line of the inclined cylinder 3 163 in the collecting assembly 16, the air pump 101 is closed and the No. 1 valve 102 is fully opened,The pressurized air enclosed in the assembly component 5 is released, the pressure in the positioning clamping part 6 disappears, and the clamping block 63 is elastically reset with the spring 1 64, releasing the fixation of the tappet. After losing the fixation, the tappet tilts and slides down and slides into the inclined cylinder 3 163, and automatically falls into the collecting cylinder 161, completing automatic drilling, grinding and material collection; when fine drilling is carried out, the tappet material to be processed is put into the feeding frame 72 along the side of the feeding component 7, and the columnar tappet material slides along the inclined feeding frame 72 and automatically inserts into the interior of the feeding cylinder 71. When it is necessary to clamp the tappet material, the electric push rod 2 is started and the support plate 3 and the positioning clamping part 6 are driven to move downward synchronously, so that the positioning clamping part 6 is gradually inserted into the interior of the feeding cylinder 71, and the support The plate 3 drives the bottom extrusion block 9 to be inserted into the linkage compression assembly 8. As the extrusion block 9 moves downward synchronously, the extrusion block 9 presses down the push plate 83 and the spring 3 84. The hydraulic oil inside the storage frame 81 is further compressed into the interior of the loading barrel 71 through the intermediate sleeve 82, and the movable plug 74 and the push rod 75 are simultaneously pushed upward, pushing the columnar tappet material falling into the loading barrel 71 into the guide sleeve 73, and further vertically correcting it along the reduction cavity in the guide sleeve 73, and cooperating with the downward sleeve 61. Then, by inputting the pressurized air in the distributed air supply assembly 10 into the positioning clamping part 6, the tappet material is automatically clamped and fixed, completing the automatic positioning and clamping, and then starting the electric push rod 2 to move upward for subsequent fine digging and drilling.
