Description

Technical Field

[0001] The invention belongs to the technical field of camshaft processing, in particular to a vertical processing tool for a camshaft. Background Art

[0002] The camshaft is a component in a piston engine. During production and processing, the forged camshaft rod is generally cut first and then finely polished. Vertical machine tools are often used to process camshafts because they have a small footprint and high space utilization.

[0003] At present, when a vertical machine tool is used to process a camshaft, a special lifting machine is required to lift the camshaft rod. During the lifting process of the camshaft rod, the posture adjustment is completed from a horizontal state to an upright state, and then the upright camshaft rod is clamped by a clamping mechanism. Finally, the clamped camshaft rod is processed. After the camshaft rod is processed, the lifting machine is still used to lift the camshaft rod so that the upright camshaft rod is laid flat. On the one hand, this processing method requires more preparation time, which affects the processing efficiency of the camshaft rod. On the other hand, the use of the lifting machine will also occupy a large space, which is not conducive to space saving. Summary of the Invention

[0021] See also Figure 1 、 Figure 2 as well as Figure 3 The present embodiment provides a vertical processing tool for a camshaft, comprising a base frame 10, a first drive assembly 20, a first clamping assembly 30, a second clamping assembly 40, a third drive assembly 60, and a detection assembly 70. A support plate 101 is fixedly provided on the upper portion of the base frame 10. The first clamping assembly 30 is slidably provided on one side of the support plate 10 for clamping one end of the camshaft rod. The first drive assembly 20 is mounted on the side wall of the support plate 101 for driving the first clamping assembly 30 to move up and down. The second clamping assembly 40 is slidably provided on the inner side of the base frame 10 for clamping the other end of the camshaft rod. The third drive assembly 60 is provided inside the base frame 10. When the first drive assembly 20 drives the clamping assembly 30 to move upward, the third drive assembly 60 is used to drive the second clamping assembly 40 to move laterally along the inner side of the base frame 10 to provide support for the camshaft rod. The detection assembly 70 is provided on the first clamping assembly 30 for detecting the vertical state of the camshaft rod.

[0022] When vertical processing is required for the camshaft, the camshaft to be processed can be placed flat on the bottom frame 10, so that one end of the camshaft acts on the first clamping assembly 30 and the other end acts on the second clamping assembly 40. Then, the first clamping assembly 30 is used to clamp one end of the camshaft, and then the first driving assembly 20 is used to drive the first clamping assembly 30 to move upward along one side of the bracket plate 101, thereby pulling one end of the camshaft upward, while the other end of the camshaft is always suspended on the second clamping assembly 40 under the action of gravity, so that the camshaft gradually rotates to a vertical state. In the above process, the second clamping assembly 40 is driven by the third driving assembly 60 to move horizontally along the inner side of the bottom frame 10 to always provide support for the other end of the camshaft. When the detection assembly 70 detects that the camshaft has rotated to a vertical state, the first driving assembly 20 stops driving the clamping assembly 30 to move upward. , the third driving assembly 60 stops driving the second clamping assembly 40 to move horizontally. At this time, the second clamping assembly 40 clamps the other end of the camshaft, and then the processing mechanism (not shown in the figure) is used to process the vertical camshaft; when the camshaft is processed, the clamping state of the other end of the camshaft by the second clamping assembly 40 is released, and then the second driving assembly 20 drives the first clamping assembly 30 to move downward, and then lowers one end of the camshaft. At the same time, the third driving assembly 60 drives the second clamping assembly 40 to move horizontally in the opposite direction along the inner side of the bottom frame 10, and then drives the other end of the camshaft to move adaptively, so that the vertical camshaft is gradually flattened. When the camshaft is flattened again on the top of the bottom frame 10, the clamping state of one end of the camshaft by the first clamping assembly 30 is released, and then the processed camshaft is removed from above the bottom frame 10.

[0023] See also Figure 1 as well as Figure 5 In one embodiment, a vertically distributed guide rail 102 is fixedly provided on the side wall of the bracket plate 101. The first driving assembly 20 includes a motor 201 and a first lead screw 202. The motor 201 is fixedly provided on the inner top wall of the bracket plate 101. The first lead screw 202 is installed at the output end of the motor 201. The first lead screw 202 is vertically distributed. The first clamping assembly 30 includes a slider 301, a first threaded sleeve 302, a first rotating shaft 303, a cover plate 304 and a base 305. The cover plate 304 is hingedly provided on the upper part of the base 305. A first arc-shaped opening 3041 is opened on one side of the cover plate 304. A second arc-shaped opening 3051 is provided on one side of the base 305 to match the first arc-shaped opening 3041, a first screw 306 is provided on the cover plate 304, and a screw hole adapted to the first screw 306 is provided on the side wall of the base 305. One end of the first rotating shaft 303 is rotatably connected to the side wall of the base 305, and the other end is fixedly connected to the first threaded sleeve 302. The slider 301 is fixedly set on the side wall of the first threaded sleeve 302, and the slider 301 is slidably matched with the guide rail 102. The first threaded sleeve 302 is sleeved on the outside of the first lead screw 202 and is threadedly matched with the first lead screw 202.

[0024] Initially, the cover plate 304 is in an open state on the upper part of the base 305. When the camshaft needs to be processed vertically, the camshaft to be processed can be placed flat on the top of the bottom frame 10 so that one end of the camshaft extends into the second arc-shaped opening 3051. Then, the cover plate 304 is rotated so that the cover plate 304 covers the upper part of the base 305. Then, the first screw 306 is screwed into the screw hole, thereby locking the cover plate 304 on the upper part of the base 305. At this time, one end of the camshaft is clamped between the first arc-shaped opening 3041 and the second arc-shaped opening Inside 3051, the motor 201 is then started, and the motor 201 drives the first screw 202 to rotate. When the first screw 202 rotates, it cooperates with the thread of the first threaded sleeve 302 to drive the first threaded sleeve 302 to move upward along the outside of the first screw 202. The first threaded sleeve 302 drives the base 305 and the cover plate 304 to move upward through the first rotating shaft 303, and then pulls one end of the camshaft rod to move upward. In this process, the camshaft rod drives the base 305 and the cover plate 304 to rotate adaptively as a whole compared to the first rotating shaft 303 under the action of gravity.

[0025] See also Figure 1 as well as Figure 7In one embodiment, the second clamping assembly 40 includes a clamping box 401, a handle 403, a second screw 404 and a clamping plate 405. The upper end of the clamping box 401 is open, and a placement groove 402 adapted to the cam shaft is provided on the upper side wall of the clamping box 401. The second screw 404 passes through the side wall of the clamping box 401 and is threadedly engaged with the clamping box 401. The handle 403 is provided at one end of the second screw 404 located outside the clamping box 401, and the clamping plate 405 is fixedly provided at one end of the second screw 404 located inside the clamping box 401.

[0026] After one end of the camshaft is placed into the second arc-shaped opening 3051 on the base 305, the camshaft can be adjusted so that the other end of the camshaft is embedded in the placement groove 402. When the motor 201 drives the first screw 202 to rotate and thereby drives the base 305, the cover plate 304 and one end of the camshaft to move upward, one end of the camshaft drives the base 305 and the cover plate 304 to rotate as a whole compared to the first rotating shaft 303, and the other end of the camshaft gradually approaches the bracket plate 101. At this time, the third driving assembly 60 is used to drive the clamping box 401 to move horizontally along the inner side of the bottom frame 10 to provide support for the other end of the camshaft to ensure that the camshaft can rotate smoothly to Vertical state. When the detection component 70 detects that the camshaft has rotated to the vertical state, the motor 201 stops driving the first screw 202 to rotate. At this time, the other end of the camshaft rotates into the inside of the clamping box 401. The staff can rotate the handle 403 to drive the second screw 404 to rotate. The second screw 404 moves toward the inside of the clamping box 401 through the threaded cooperation between the second screw 404 and the clamping box 401, thereby driving the clamping plate 405 to move synchronously. When the clamping plate 405 moves, it acts on the side wall of the camshaft, thereby clamping the camshaft, so that the camshaft can maintain a stable vertical state to improve the subsequent processing quality of the camshaft.

[0027] See also Figure 1 In one embodiment, a second driving assembly 50 is further provided under the clamping box 401. After the clamping plate 405 clamps the camshaft, the second driving assembly 50 is used to drive the clamping box 401 to rotate, thereby driving the camshaft to rotate, so that the processing mechanism can subsequently perform rotation processing on the camshaft.

[0028] See also Figure 1 as well as Figure 7In one embodiment, the second driving assembly 50 includes a protective box 501 and a second rotating shaft 504. The protective box 501 is arranged below the clamping box 401. A driving motor (not shown in the figure) is arranged inside the protective box 501. One end of the second rotating shaft 504 is connected to the output end of the driving motor, and the other end extends to the outside of the protective box 501 and is fixedly connected to the bottom of the clamping box 401.

[0029] When the third drive assembly 60 drives the clamping box 401 to move horizontally along the inner side of the bottom frame 10 to provide support for the other end of the camshaft, the clamping box 401 drives the protective box 501, the drive motor and the second rotating shaft 504 to move horizontally synchronously. When the camshaft rotates to a vertical state and the clamping plate 405 clamps the camshaft, the drive motor can be started. The drive motor drives the clamping box 401 to rotate through the second rotating shaft 504, and then drives the camshaft to rotate, so that the processing mechanism can perform rotation processing on the camshaft.

[0030] See also Figure 3 as well as Figure 4 In one embodiment, a second threaded sleeve 503 is fixedly provided on the side wall of the protective box 501, and the third drive assembly 60 includes a first bevel gear 601, a second bevel gear 602 and a second lead screw 603. The first bevel gear 601 is fixedly provided at an end of the first lead screw 202 away from the motor 201, and the second lead screw 603 is rotatably installed on the inner side of the bottom frame 10. The second bevel gear 602 is fixedly provided on the outside of the second lead screw 603 and meshes with the first bevel gear 601. The second threaded sleeve 503 is sleeved on the outside of the second lead screw 603 and is threadedly engaged with the second lead screw 603.

[0031] When the motor 201 drives the first lead screw 202 to rotate and then pulls one end of the camshaft rod upward through the base 305 and the cover plate 304, the first lead screw 202 also drives the first bevel gear 601 to rotate, and through the meshing action of the first bevel gear 601 and the second bevel gear 602, it drives the second lead screw 603 to rotate. When the second lead screw 603 rotates, it cooperates with the thread of the second threaded sleeve 503 to drive the protective box 501 to move horizontally along the inner side of the bottom frame 10. The protective box 501 drives the clamping box 401 to move horizontally synchronously to provide support for the other end of the camshaft rod.

[0032] See also Figure 1 as well as Figure 3 In one embodiment, a guide rod 103 is fixedly provided inside the bottom frame 10, and a sliding sleeve 502 is fixedly provided on the side wall of the protection box 501. The sliding sleeve 502 is slidably sleeved on the outside of the guide rod 103, so that when the second screw 603 rotates, it can smoothly drive the protection box 501 and the clamping box 401 to move horizontally along the inner side of the bottom frame 10.

[0033] When the driving motor drives the clamping box 401 to rotate, in order to prevent one end of the cam shaft from being clamped inside the first arc-shaped opening 3041 and the second arc-shaped opening 3051, thereby affecting the smooth rotation of the cam shaft, please refer to Figure 5 as well as Figure 6 In one embodiment, a plurality of supports 308 are fixedly provided on the inner walls of the first arc-shaped opening 3041 and the second arc-shaped opening 3051, and a group of roller rods 307 are rotatably provided on one side of each group of supports 308, and the plurality of roller rods 307 are axially distributed along the first arc-shaped opening 3041 and the second arc-shaped opening 3051.

[0034] When the first screw 306 is screwed into the screw hole and the cover 304 is locked on the upper part of the base 305, several rollers 307 act evenly on the outer wall of the camshaft to clamp one end of the camshaft, so that the camshaft cannot be separated from the first arc-shaped opening 3041 and the second arc-shaped opening 3051. When the driving motor drives the clamping box 401 to rotate through the second rotating shaft 504, the clamping box 401 can drive the camshaft to rotate. When the camshaft rotates, the friction effect drives the several rollers 307 to rotate relative to the corresponding supports 308, thereby ensuring the smooth and stable rotation of the camshaft to facilitate rotation processing.

[0035] See also Figure 6 In one embodiment, a slot 309 is provided on the side wall of the base 305, and the detection assembly 70 includes a first conductive rod 701, a rotating wheel 702, a support shaft 703, an indicator light 704, a power supply 705, a second conductive rod 706 and a power connection block 707. The rotating wheel 702 is arranged inside the slot 309, one end of the support shaft 703 is rotatably connected to the inner wall of the slot 309, and the other end is fixedly connected to the eccentric position of the side wall of the rotating wheel 702, the power connection block 707 is fixedly provided on the circumferential side wall of the rotating wheel 702, and the power supply 705 is fixedly provided on the outer wall of the base 305. One end of the first conductive rod 701 is connected to the negative terminal of the power supply 705, and the other end is connected in series with the indicator light and then distributed opposite to the second conductive rod 706. The end of the second conductive rod 706 away from the first conductive rod 701 is connected to the positive terminal of the power supply 705.

[0036] Initially, the rotating wheel 702 is affected by its own weight, causing the power block 707 to droop naturally inside the slot 309. At this time, the power block 707 is separated from the first conductive rod 701 and the second conductive rod 706, and the indicator light 704 is off. As the motor 201 drives the first lead screw 202 to rotate, thereby driving one end of the cam shaft to gradually move upward, the one end of the cam shaft drives the base 305 to rotate adaptively relative to the first rotating shaft 303. Under the action of its own gravity, the rotating wheel 702 drives the support shaft 703 to rotate adaptively relative to the inner wall of the slot 309, thereby driving the power block 707 to gradually approach the first conductive rod 701. 01 and the second conductive rod 706. When the camshaft rotates to a vertical state, the power block 707 contacts the first conductive rod 701 and the second conductive rod 706. At this time, the power supply 705 supplies power to the indicator light 704 through the second conductive rod 706, the power block 707 and the first conductive rod 701, and the indicator light 704 lights up. The staff uses the lighting signal of the indicator light 704 to conclude that the camshaft rotates to a vertical state, and then shuts down the motor 201 to keep the camshaft in a vertical state, and then starts the drive motor, thereby driving the clamping box 401 and the camshaft to rotate, thereby realizing the rotation processing of the camshaft.

[0037] In the embodiment of the present invention, when vertical processing is required for the camshaft, the camshaft to be processed can be placed flat on the top of the base frame 10, so that one end of the camshaft acts on the first clamping assembly 30 and the other end acts on the second clamping assembly 40. Then, the first clamping assembly 30 is used to clamp one end of the camshaft, and then the first driving assembly 20 drives the first clamping assembly 30 to move upward along one side of the bracket plate 101, thereby pulling one end of the camshaft upward, while the other end of the camshaft always hangs on the second clamping assembly 40 under the action of gravity, so that the camshaft gradually rotates to a vertical state. During the above process, the second clamping assembly 40 is driven by the third driving assembly 60 to move laterally along the inner side of the base frame 10 to always provide support for the other end of the camshaft. When the detection assembly 70 detects that the camshaft has rotated to a vertical state, the first driving assembly 20 stops driving the clamping assembly 30 to move upward, and the third driving assembly 60 stops driving the second clamping assembly 40 to move laterally. At this time, the second clamping assembly 40 is used to clamp the other end of the camshaft. The camshaft is clamped in a row, and then the processing mechanism (not shown in the figure) is used to process the camshaft in a vertical state; when the camshaft is processed, the second clamping assembly 40 is released from the clamping state of the other end of the camshaft, and then the second driving assembly 20 drives the first clamping assembly 30 to move downward, thereby lowering one end of the camshaft, and at the same time, the third driving assembly 60 drives the second clamping assembly 40 to move laterally in the opposite direction along the inner side of the base frame 10, thereby driving the other end of the camshaft to move adaptively, so that the camshaft in the vertical state is gradually leveled. When the camshaft is leveled above the base frame 10 again, the clamping state of the first clamping assembly 30 on one end of the camshaft is released, and then the processed camshaft is removed from above the base frame 10. Compared with the prior art, when the camshaft is processed vertically, there is no need to rely on a lifting machine, and the camshaft can be automatically erected and leveled, thereby improving the processing efficiency of the camshaft, and the vertical state of the camshaft can be detected during the erection process, thereby improving the processing quality.

[0038] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
