Description

TECHNICAL FIELD

[0002] In the machining process of the gear box end cover, the drilling operation is a very critical process, and its machining quality is directly related to the overall performance and service life of the gear box. At present, the tooling equipment for machining the gear box end cover on the market has many problems to be solved in actual application.

[0003] The tooling equipment in the prior art mostly lacks a real-time monitoring mechanism for the working state of the drill bit. Specifically, the rotation speed and temperature of the drill bit during the machining process cannot be effectively monitored. During machining, the drill bit may have a problem of excessively high temperature due to excessive mechanical load, tool wear, or unreasonable cutting parameter setting. If this situation cannot be discovered and handled in time, not only will the degree of tool wear be aggravated, but also the machining quality of the workpiece will be adversely affected, and in severe cases, the drill bit may even break, posing a safety hazard.

[0004] At the same time, the rotation speed of the drill bit may also be abnormal due to factors such as temperature change, load fluctuation, or system failure. Once the rotation speed is abnormal, the machining precision will be affected, thereby causing damage to the workpiece. In addition, due to the lack of effective monitoring means, the operator cannot timely understand the working state of the drill bit, which not only increases the wear of the machine tool, but also increases the maintenance cost of the equipment.

[0033] As a preferred solution, further, as Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the temperature monitoring mechanism 8 includes: a slider 81, a clamping clamp 82, an extrusion cavity 83, a driving cavity 84, a support seat 85, a pressure sensor 86, an extrusion rod 87, a spring 88, a first rolling ball 89, a contact 810, a second rolling ball 811, a first wire 812, a second wire 813, an electronic ammeter 814 and a screw 815. There are eight sliders 81, and the eight sliders 81 are grouped into two groups of four. The two groups of sliders 81 are slidably adapted to be connected to the left and right sides of the outer walls of the four guide rods 7. There are two clamping clamps 82, and each clamping clamp 82 is respectively arranged between the outer walls of four groups of sliders 81. The top of the clamping clamp 82 is provided with an extrusion cavity 83, and the bottom of one of the clamping clamps 82 is provided with a driving cavity 83. Cavity 84, support seat 85 is arranged on the outside of the top end of the clamping clamp 82, and pressure sensor 86 is arranged on the inner side of support seat 85. Pressure sensor 86 is prior art and will not be described in detail here. Pressure sensor 86 is used to monitor the contact degree between extrusion rod 87 and drill bit 5. Extrusion rod 87 is slidably adapted to be inserted into the inner cavity of extrusion cavity 83. The inner end of extrusion rod 87 extends into the inner cavity of clamping clamp 82, and the outer end of extrusion rod 87 extends out of the inner cavity of extrusion cavity 83 and contacts with pressure sensor 86. Spring 88 is sleeved on the outer wall of extrusion rod 87, one end of spring 88 is clamped on the outer wall of extrusion rod 87, and the other end of spring 88 is clamped on the outer side of the inner cavity of extrusion cavity 83. Spring 88 is a rotating spring, which is squeezed or pulled by external force. After stretching, it undergoes elastic deformation and returns to its initial state after the external force is removed. The spring 88 is used to push the extrusion rod 87 to move. The first ball 89 is rotatably embedded in the inner cavity of the extrusion rod 87. The outer wall of the first ball 89 contacts the outer wall of the drill 5. The friction between the clamping clip 82 and the drill 5 can be reduced by the ball 89. The length of the first ball 89 embedded in the inner cavity of the extrusion rod 87 is greater than its radius, which prevents the first ball 89 from escaping from the inner cavity of the extrusion rod 87. The contact 810 is provided in the inner cavity of the clamping clip 82. The second ball 811 is rotatably embedded in the inner cavity of the contact 810. The outer wall of the second ball 811 contacts the outer wall of the drill 5. The inner side of the outer wall of the second ball 811 and the inner side of the outer wall of the first ball 89 are in the same vertical plane, which is beneficial to the The second ball 811 can reduce the friction between the clamping clip 82 and the drill bit 5. The length of the second ball 811 embedded in the inner cavity of the contact 810 is greater than its radius, preventing the second ball 811 from escaping from the inner cavity of the contact 810. One end of the first wire 812 is set on the outer wall of one of the contacts 810, and the other end of the first wire 812 extends out of the outer wall of the clamping clip 82. The first wire 812 is used to connect to a power source. The other end of the second wire 813 is set on the outer wall of another contact 810, and the other end of the second wire 813 extends out of the outer wall of the clamping clip 82. The second wire 813 is used to connect the circuit. The electronic ammeter 814 is set at the bottom right end of the mounting base 2, and the other end of the second wire 813 is connected to the electronic ammeter 814.The electronic ammeter 814 is electrically connected with the driving motor 4. The electronic ammeter 814 is a prior art and will not be described here. The electronic ammeter 814 is used to monitor the current of the circuit. The number of the screw rods 815 is two. The inner ends of the two screw rods 815 are rotatably arranged in the middle part of the outer wall of the clamping clamp 82 through bearings. The outer ends of the screw rods 815 extend out of the inner cavity of the detection cavity 3. The outer wall of the screw rod 815 is screwed to the outer wall of the mounting seat 2. The rotation force generated by the rotation of the screw rod 815 can drive the clamping clamp 82 to move.

[0034] Mounting and contact adjustment: by rotating the screw rod 815, the clamping clamp 82 can be driven to move along the guide rod 7, so that the first rolling ball 89 and the second rolling ball 811 are in contact with the outer wall of the drill bit 5. When the clamping clamp 82 moves, the extrusion rod 87 is extruded outward by the drill bit 5 and compresses the spring 88. The outer end of the extrusion rod 87 abuts against the pressure sensor 86. The pressure value is read through the display 6 to confirm that the contact pressure is appropriate.

[0035] Temperature monitoring mechanism: when the drill bit 5 rotates, the first wire 812 is connected with the power supply, so that the current forms a loop through the contact 810, the second rolling ball 811, the drill bit 5, the first rolling ball 89, the contact 810 and the second wire 813. If the drill bit 5 is heated due to cutting and the temperature rises, the resistance value increases with the temperature rise. Under the condition that the power supply voltage is constant, the circuit current value monitored by the electronic ammeter 814 will decrease. When the current value is lower than the set threshold value, the electronic ammeter 814 sends a signal to the main controller to trigger the driving motor 4 to stop working, so as to avoid the drill bit from being overheated, worn or broken.

[0036] Friction optimization design: the first rolling ball 89 and the second rolling ball 811 can rotate with the drill bit 5. By replacing sliding friction with rolling friction, the resistance of the monitoring mechanism to the rotation of the drill bit 5 is reduced, so as to ensure the accuracy of temperature monitoring and the stability of the device.

[0037] As a preferred solution, further, Figure 9As shown, the rotation speed monitoring mechanism 9 comprises a connecting seat 91, a Hall rotation speed sensor 92, a rotating rod 93, a rubber roller 94 and a missing tooth signal disc 95. The connecting seat 91 is arranged at the outer side of the bottom end of one clamping clamp 82, the Hall rotation speed sensor 92 is arranged at the inner side of the connecting seat 91, the Hall rotation speed sensor 92 is electrically connected with the driving motor 4, the Hall rotation speed sensor 92 is a prior art which will not be described in detail here, the Hall rotation speed sensor 92 is used here to cooperate with the missing tooth signal disc 95 to detect the rotation speed of the drill bit 5, the upper and lower ends of the rotating rod 93 are rotatably arranged on the upper and lower sides of the inner cavity of the driving cavity 84 through bearings, the rubber roller 94 is sleeved on the outer wall of the rotating rod 93 and locked, the outer wall of the rubber roller 94 is in contact with the outer wall of the drill bit 5, the inner side of the outer wall of the rubber roller 94 and the inner side of the outer wall of the first rolling ball 89 are in the same vertical plane, the friction between the rubber roller 94 and the drill bit 5 can drive the missing tooth signal disc 95 to rotate, the missing tooth signal disc 95 is sleeved on the outer wall of the rotating rod 93 and locked through a jack, the position of the missing tooth signal disc 95 corresponds to the position of the Hall rotation speed sensor 92, the missing tooth signal disc 95 is a prior art which will not be described in detail here, and the missing tooth signal disc 95 is used here to cooperate with the Hall rotation speed sensor 92 to detect the rotation speed of the drill bit 5.

[0038] Rotation speed transmission mechanism: when the drill bit 5 rotates, the rubber roller 94 is driven to rotate synchronously through friction, and the rubber roller 94 drives the missing tooth signal disc 95 to rotate through the rotating rod 93; since the rubber roller 94 is in direct contact with the drill bit 5, the rotation speed of the rubber roller 94 has a linear correspondence with the rotation speed of the drill bit 5, thereby ensuring accurate transmission of the rotation speed signal.

[0039] Signal monitoring logic: when the missing tooth signal disc 95 rotates with the rotating rod 93, the tooth structure thereof cuts the magnetic field of the Hall rotation speed sensor 92, thereby generating a pulse signal; the Hall rotation speed sensor 92 calculates the rotation speed of the drill bit 5 according to the number of pulses in a unit time, and feeds back data to the main controller.

[0040] Abnormal response mechanism: if the rotation speed of the drill bit 5 is lower than a set threshold value due to load change, temperature abnormality or system failure, the Hall rotation speed sensor 92 sends an abnormal signal to the main controller, thereby triggering the driving motor 4 to stop, so as to avoid that the machining precision is reduced or the workpiece is damaged due to abnormal rotation speed.

[0041] Working principle, specifically comprising the following steps:

[0042] Step one, in use, the workpiece is fixed on the drill 1, the other end of the first wire 812 is connected with the external power supply, the power supply, the first wire 812, the contact 810, the second ball 811, the drill bit 5, the second wire 813 and the electronic ammeter 814 form a path, the drill 1 drives the movement of the mounting seat 2, the driving motor 4 and the drill bit 5, the driving motor 4 drives the rotation of the drill bit 5, and the drill bit 5 is used for processing the workpiece;

[0043] Step two, while the drill bit 5 is rotating, the friction force is used to make the first ball 89, the second ball 811 and the rubber roller 94 rotate, the rubber roller 94 rotates the toothless signal disc 95 through the rotating rod 93 to drive the rotation of the toothless signal disc 95, the toothless signal disc 95 rotates and cooperates with the hall type speed sensor 92 to monitor the rotation speed of the drill bit 5, prevents the drill bit 5 from being abnormal due to temperature change, load change or system failure, when the rotation speed is abnormal, the hall type speed sensor 92 transmits the signal to the main controller, and the main controller closes the driving motor 4, avoids affecting the processing precision, and avoids the damage of the workpiece;

[0044] Step three, when the drill bit 5 rotates, if the drill bit 5 is too high due to mechanical load, tool wear or improper cutting parameters, etc., because the material of the drill bit 5 is usually high speed tool steel or hard alloy, and if the temperature of the drill bit 5 is too high, the resistance of the drill bit 5 will increase, and under the condition that the power supply voltage is constant, the circuit current detected by the electronic ammeter 814 will decrease, so that the temperature of the drill bit 5 is monitored in real time, if the circuit current value detected by the electronic ammeter 814 is too low, the electronic ammeter 814 transmits the signal to the main controller, and the main controller closes the driving motor 4, avoids aggravating the tool wear, affects the processing quality of the workpiece, prevents the drill bit from breaking, and eliminates the safety hazard;

[0045] Step four, when the drill bit 5 needs to be replaced, rotate the screw rod 815, the rotation force generated by the rotation of the screw rod 815 can drive the clamping clamp 82 to move outward, and then push the extrusion rod 87 to move inward under the elastic force of the spring 88 until the spring 88 returns to normal, until the clamping clamp 82 moves to the appropriate position, and the drill bit 5 is replaced. After the drill bit 5 is replaced, rotate the screw rod 815 in the opposite direction, so as to promote the clamping clamp 82 to move inward until the first ball 89 and the outer wall of the drill bit 5 are in contact. The clamping clamp 82 continues to move inward, that is, the drill bit 5 can be used to push the extrusion rod 87 to move outward, and the spring 88 is elastically deformed, until the outer end of the extrusion rod 87 is in contact with the pressure sensor 86. The extrusion rod 87 can be used to extrude the pressure sensor 86, the pressure sensor 86 is used to detect the pressure value, and the value is displayed through the display 6. The operator can judge the contact between the rubber roller 94 and the drill bit 5 by reading the value displayed on the display 6 until the pressure value reaches the appropriate range.

[0046] In summary, the device can effectively monitor the rotation speed and temperature of the drill bit 5, ensure stable cutting parameters during processing, and avoid the situation that the drill bit 5 is overheated during processing, which can cause tool wear and affect the processing quality of the workpiece. The device can also prevent the drill bit 5 from breaking and eliminate safety hazards. At the same time, it can prevent the drill bit 5 from affecting the processing precision due to abnormal rotation speed, which can cause damage to the workpiece, and reduce the wear and maintenance cost of the machine tool.

[0047] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
