Description
Technical Field
[0001] The invention relates to the technical field of camshaft processing, in particular to an intelligent camshaft center hole processing machine. Background Art
[0002] The camshaft is an important component in the internal combustion engine, which is used to control the opening and closing of the valves and other related mechanical movements. There are usually a series of cams on the camshaft. The shapes of these cams vary according to the needs of the engine design. Their shapes determine when the valves open and close, as well as the lift and duration when they are opened. Through the design of the cams on the camshaft, the timing and duration of the engine's intake and exhaust can be controlled, thereby affecting the efficiency and performance of the engine. During the processing of the camshaft, a center hole needs to be opened. The center hole is used to determine the center of the workpiece so that subsequent processing operations can be performed accurately around this center to ensure processing accuracy. In traditional processing methods, the center hole needs to be processed at one end first, and then subsequent processes such as rough processing, fine processing, etc. are performed, and finally the center hole is processed at the other end. In the subsequent processing process, each clamping may introduce new positioning errors. These errors will accumulate during multiple clamping and positioning processes, and eventually cause the center hole processed later to deviate from the position of the center hole processed earlier. For this reason, we propose a drilling and tapping machine. Summary of the invention

[0029] The fixing assembly 5 is arranged on the processing table 1 , and the camshafts of different shapes are fixed by the fixing assembly 5 .
[0030] The advantage of the fixing component 5 is that it can clamp and fix camshafts of different shapes. Since it can clamp camshafts of various shapes, the time for replacing the clamping device or adjusting the equipment is reduced. In a production line or working environment, this means that it is possible to quickly switch from one camshaft to another, thereby improving the overall processing efficiency. Using a single processing tool to adapt to a variety of camshaft shapes can reduce the need for multiple special processing equipment, which not only reduces the equipment investment cost, but also reduces the cost of storing and maintaining multiple processing machines.
[0031] The positioning mechanism 8 is arranged on the mounting frame 2. The positioning mechanism 8 drives the positioning rod 4 to move, and synchronously drives the tool 3 to move, so as to locate the position of the unprocessed center hole on the camshaft.
[0032] The advantage of setting up the positioning mechanism 8 is that it can quickly locate the unmachined center hole on the camshaft according to the position of the machined center hole. At the same time, by using the machined center hole as a reference, the uniformity of the reference can be ensured throughout the entire processing process, thereby avoiding the accumulation of errors caused by changing the reference, thereby improving the positioning accuracy. Moreover, by using the same reference to machine the center holes at both ends, it can be ensured that the center holes at both ends of the camshaft have a high degree of coaxiality, which is crucial to maintaining the performance and stability of the camshaft, and also reduces the problem of center hole deviation caused by poor coaxiality.
[0033] The fixing assembly 5 includes a plurality of fasteners 6 disposed on the processing table 1 , through which the camshaft is fixed, and an adjusting member 7 is disposed on the fastener 6 , through which the position of the fastener 6 on the processing table 1 is adjusted.

The adjusting screw 72 passes through the movable seat 61 and is threadedly connected to the movable seat 61 , and an adjusting knob 73 is arranged at the end of the adjusting screw 72 .
[0036] The advantage of setting the adjusting member 7 is that it can clamp and fix camshafts of different shapes. Since it can clamp camshafts of various shapes, the time for replacing the clamping device or adjusting the equipment is reduced. In a production line or working environment, this means that it is possible to quickly switch from one camshaft to another, thereby improving the overall processing efficiency.
[0037] When in use, the staff adjusts the position of the movable seat 61 according to the shape of the camshaft. First, the staff turns the adjusting knob 73 to drive the adjusting screw 72 to rotate, and drives the movable seat 61 to move, thereby adjusting the position of the movable seat 61 on the processing table 1. After adjusting the movable seat 61 to a suitable position, the camshaft is placed in the adapter groove 65 on the movable seat 61. The setting of the arc-shaped adapter groove 65 can make the camshaft clamped more stably. After the placement is completed, the fastening screw 62 is turned to drive the locking plate 63 to descend, and the adapter groove 65 on the locking plate 63 is controlled to contact the camshaft to clamp and fix the camshaft. The setting of the limit rod 64 prevents the locking plate 63 from rotating with the fastening screw 62.
[0038] The positioning mechanism 8 includes a mounting member 9 arranged on the mounting frame 2, and the tool 3 and the positioning rod 4 are installed on the mounting frame 2 through the mounting member 9. The mounting frame 2 is provided with a transverse positioning member 10, and the horizontal position of the unmachined center hole on the camshaft is positioned through the transverse positioning member 10. The mounting frame 2 is provided with a vertical positioning member 11, and the vertical position of the unmachined center hole on the camshaft is positioned through the vertical positioning member 11. The positioning rod 4 is provided with an adjustment member 12, and the positioning rod 4 is controlled by the adjustment member 12 to move to the center position of the machined center hole.
[0039] The mounting member 9 includes a sliding groove 91 provided on the mounting frame 2, wherein a plurality of the sliding grooves 91 are respectively provided with a moving plate 1 92 and a moving plate 2 93, and the contacting surface of the moving plate 1 92 with the sliding groove 91 is made of rubber material, so as to provide friction resistance for the moving plate 1 92 when it moves in the sliding groove 91, and a mounting groove 1 94 and a mounting groove 2 95 are respectively provided in the moving plate 1 92 and the moving plate 2 93, and a driving groove 96 is provided on the moving plate 1 92, and the driving groove 96 penetrates the mounting groove 1 94, and the mounting groove A sliding block 97 is slidably arranged in one 94, the positioning rod 4 passes through the sliding block 97 and is slidably connected to the sliding block 97, the positioning rod 4 passes through the driving groove 96 and is movably connected to the driving groove 96, a displacement groove 98 is opened on the movable plate 93, the displacement groove 98 is connected to the installation groove 95, a sliding block 99 is slidably arranged in the installation groove 95, a connecting block 910 is arranged on the sliding block 99, the connecting block 910 is connected to the tool 3, and the connecting block 910 is slidably connected to the displacement groove 98.
[0040] The contact surface of the moving plate 1 92 with the sliding groove 91 is made of rubber material, which provides friction resistance for the moving plate 1 92 when it moves in the sliding groove 91, so that the moving plate 1 92 will move only when a sufficiently large thrust is applied from the outside.
[0041] The transverse positioning member 10 includes a plurality of rotating shafts 101 rotatably arranged in the mounting groove 1 94 and the mounting groove 2 95, the rotating shaft 101 is provided with a positioning gear 102, the positioning gear 102 is provided with a toothed belt 103, the plurality of toothed belts 103 are respectively connected with the sliding block 1 97 and the sliding block 2 99, a plurality of extension shafts 104 are rotatably arranged on the processing table 1, the plurality of extension shafts 104 respectively penetrate the rotating shaft 101, the moving plate 1 92 and the moving plate 2 93 and are slidably connected with the rotating shaft 101, the moving plate 1 92 and the moving plate 2 93, the plurality of extension shafts 104 are all provided with a linkage gear 106, the linkage gear 106 is provided with a synchronous belt 107.
[0042] The benefit of the transverse positioning member 10 is that it can quickly position the position of the other end of the camshaft that has not been drilled in the horizontal direction according to the end of the camshaft that has been drilled.
[0043] When in use, first move the positioning rod 4 to drive the sliding block 97 to slide in the installation groove 94. When the sliding block 97 slides, it drives the toothed belt 103 connected to it to move. The movement of the toothed belt 103 drives the positioning gear 102 to rotate. The rotation of the positioning gear 102 drives the rotating shaft 101 to rotate synchronously. When the rotating shaft 101 rotates, it drives the extension shaft 104 slidably connected to it to rotate. When the extension shaft 104 rotates, it drives another extension shaft 104 among the multiple extension shafts 104 to rotate through the interlocking gear 106 and the synchronous belt 107, thereby driving the toothed belt 103 connected to the sliding block 2 99 to move, so that the tool 3 connected to the sliding block 2 99 moves synchronously with the positioning rod 4.
[0044] The vertical positioning member 11 includes a positioning plate 111 arranged on the mounting frame 2, and a positioning screw 112 is rotatably arranged on the positioning plate 111, and the positioning screw 112 penetrates the movable plate 2 93 and is threadedly connected to the movable plate 2 93, and the positioning screw 112 is rotatably connected to the processing table 1, and a clockwork box 113 is arranged on the processing table 1, and the positioning screw 112 penetrates the clockwork box 113 and is rotatably connected to the clockwork box 113, and a clockwork spring 114 is arranged in the clockwork box 113, and one end of the clockwork spring 114 is connected to the positioning screw 112, and a winding wheel 115 is arranged on the positioning screw 112, and a traction rope 116 is arranged on the winding wheel 115, and a guide block 117 is arranged on the processing table 1, and the traction rope 116 penetrates the guide block 117 and is connected to the movable plate 1 92, and the traction rope 116 is movably connected to the guide block 117.
[0045] While moving the positioning rod 4 laterally, the staff synchronously drives the positioning rod 4 to move vertically and drives the moving plate 1 92 to move. When the positioning rod 4 coincides with the center hole that has been processed on the camshaft, the positioning rod 4 is pushed into the center hole. When the moving plate 1 92 descends, the traction rope 116 is released, so that the clockwork spring 114 releases the force and drives the winding wheel 115 and the positioning screw 112 to rotate. The winding wheel 115 rotates to reel in the traction rope 116, and the rotation of the positioning screw 112 drives the moving plate 2 93 to descend, and synchronously drives the tool 3 on the moving plate 2 93 to descend. When the moving plate 1 92 rises, the traction rope 116 is stretched, and the winding wheel 115 is driven to rotate to release the traction rope 116. The rotation of the winding wheel 115 drives the positioning screw 112 to rotate, thereby driving the moving plate 2 93 to rise.
[0046] The adjusting member 12 includes a through slot 121 provided on the positioning rod 4, a plurality of receiving slots 122 provided on the positioning rod 4, the receiving slots 122 being connected to the through slot 121, an extension shaft 123 being provided in the receiving slot 122, an extension plate 124 being rotatably provided on the extension shaft 123, a connecting seat 125 being provided on the extension plate 124, a connecting rod 126 being rotatably provided on the connecting seat 125, a connecting plate 127 being slidably provided in the through slot 121, a connecting seat 2 128 being provided on the connecting plate 127, the connecting seat 2 128 being rotatably connected to the connecting rod 126, a pushing rod 129 being provided in the through slot 121, the pushing rod 129 being threadedly connected to the through slot 121, and the pushing rod 129 being rotatably connected to the connecting plate 127.
[0047] The benefit of setting the adjustment member 12 is that the positioning rod 4 can adapt to a variety of center holes with different aperture sizes, thereby making the positioning of the unprocessed center hole at the other end more accurate.
[0048] If the diameter of the center hole is larger than the positioning rod 4, first rotate the push rod 129 to drive the connecting plate 127 to move in the through groove 121, and compress the connecting rod 126 rotatably set on the connecting plate 127, so that the connecting rod 126 deflects. When the connecting rod 126 deflects, it drives the extension plate 124 to rotate around the extension axis 123, so that the extension plate 124 expands in the center hole, thereby ensuring that the positioning rod 4 is always in the axial position of the center hole.
[0049] When in use, the staff adjusts the position of the movable seat 61 according to the shape of the camshaft. First, the staff turns the adjusting knob 73 to drive the adjusting screw 72 to rotate, and drives the movable seat 61 to move, thereby adjusting the position of the movable seat 61 on the processing table 1. After adjusting the movable seat 61 to a suitable position, the camshaft is placed in the adapter groove 65 on the movable seat 61. The setting of the arc-shaped adapter groove 65 can make the camshaft clamped more stably. After the placement is completed, the fastening screw 62 is turned to drive the locking plate 63 to descend, and the adapter groove 65 on the locking plate 63 is controlled to contact the camshaft to clamp and fix the camshaft. The setting of the limit rod 64 prevents the locking plate 63 from rotating with the fastening screw 62.
[0050] Then move the positioning rod 4, driving the sliding block 197 to slide in the installation groove 194. The sliding block 197 slides and drives the toothed belt 103 connected to it to move. The movement of the toothed belt 103 drives the positioning gear 102 to rotate. The rotation of the positioning gear 102 drives the rotating shaft 101 to rotate synchronously. The rotation of the rotating shaft 101 drives the extension shaft 104 slidably connected to it to rotate. The rotation of the extension shaft 104 drives another extension shaft 104 among the multiple extension shafts 104 to rotate through the interlocking gear 106 and the synchronous belt 107, thereby driving the toothed belt 103 connected to the sliding block 299 to move, so that the tool 3 connected to the sliding block 299 moves synchronously with the positioning rod 4.
[0051] While moving the positioning rod 4 laterally, the staff synchronously drives the positioning rod 4 to move vertically and drives the moving plate 1 92 to move. When the positioning rod 4 coincides with the center hole that has been processed on the camshaft, the positioning rod 4 is pushed into the center hole. When the moving plate 1 92 descends, the traction rope 116 is released, so that the clockwork spring 114 releases the force and drives the winding wheel 115 and the positioning screw 112 to rotate. The winding wheel 115 rotates to reel in the traction rope 116, and the rotation of the positioning screw 112 drives the moving plate 2 93 to descend, and synchronously drives the tool 3 on the moving plate 2 93 to descend. When the moving plate 1 92 rises, the traction rope 116 is stretched, and the winding wheel 115 is driven to rotate to release the traction rope 116. The rotation of the winding wheel 115 drives the positioning screw 112 to rotate, thereby driving the moving plate 2 93 to rise.
[0052] When the diameter of the center hole is larger than the positioning rod 4, firstly rotate the push rod 129 to drive the connecting plate 127 to move in the through groove 121, and press the connecting rod 126 rotatably set on the connecting plate 127, so that the connecting rod 126 deflects. When the connecting rod 126 deflects, it drives the extension plate 124 to rotate around the extension axis 123, so that the extension plate 124 expands in the center hole, thereby ensuring that the positioning rod 4 is always in the axial position of the center hole.
[0053] Embodiment 2: Please refer to FIG. 10 , the present invention provides a technical solution:
[0054] Different from Example 1, a friction pad 13 is arranged in the adapter groove 65, and the friction pad 13 is made of rubber. The advantage of the arrangement of the friction pad 13 is that the friction between the friction pad 13 and the camshaft is increased, so that the fixation of the camshaft is more stable, thereby avoiding the movement of the camshaft during the drilling process and affecting the drilling quality of the center hole.
