[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] As mentioned earlier, boring is a hole-making process in the machining field, widely used in aerospace, energy, shipbuilding, heavy machinery, and other industries. The main task of boring is to finish cast, drilled, and punched holes to ensure that the machined holes meet requirements for diameter, shape accuracy, positional accuracy, and surface finish. Currently, boring equipment is used to bore metal parts. However, current boring equipment transmits power between the motor and spindle through gears inside a gearbox. Excessive boring depth, poor internal lubrication, and other factors can damage the internal gears or bearings of the gearbox, leading to time-consuming and costly repairs. For example, repairing a gearbox requires disassembling it and replacing the internal gears and bearings, with each repair taking approximately 4-6 hours.

[0038] This application provides a boring machine, which includes a mounting plate, a motor, a transmission mechanism, and a spindle box. The motor, transmission mechanism, and spindle box are all connected to the mounting plate. The transmission mechanism includes a transmission belt and a transmission shaft. The motor drives the transmission shaft to rotate through the transmission belt. When the transmission shaft rotates, it drives the spindle in the spindle box to rotate, thereby driving the boring tool to perform boring operations through the spindle, realizing the boring processing of metal parts. Since the transmission is carried out through a transmission belt, the cost is lower compared with the gear transmission in the gearbox in the prior art. Moreover, the replacement process of the transmission belt after wear is simpler, and compared with replacing the gears in the gearbox, it can save maintenance time.

[0039] It should be noted that the accompanying drawings in this application are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this application in any way. They are not necessarily drawn to scale.

[0040] The boring equipment provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1 This is a schematic diagram of a boring device provided in an embodiment of this application. Figure 1 As shown, the boring machine 10 includes: a mounting plate 11, a motor 12, a transmission mechanism 13, and a spindle box 14.

[0042] The transmission mechanism 13 includes a transmission belt 131 and a transmission shaft 132. The transmission belt 131 can be a belt. The motor 12, transmission shaft 132, and spindle box 14 are connected to the mounting plate 11. The motor 12, transmission mechanism 13, and spindle box 14 can be fixed by the mounting plate 11. Optionally, the mounting plate 11 can be connected to a fixing frame to fix the relative position of the mounting plate 11 to the ground.

[0043] The transmission belt 131 is connected to the transmission shaft 132 and the output end of the motor 12 respectively. When the boring machine 10 performs boring operation, the output end of the motor 12 rotates and drives the transmission shaft 132 to rotate through the transmission belt 131. When the transmission shaft 132 rotates, it drives the spindle 141 of the spindle box 14 to rotate, so that the boring tool can be driven to perform boring operation through the spindle 141.

[0044] Optionally, in this embodiment, the axis of the drive shaft 132 coincides with the axis of the spindle 141 in the spindle box 14, and the axis of the drive shaft 132 and the axis of the spindle 141 in the spindle box 14 are perpendicular to the ground. That is, the boring machine 10 in this embodiment can be a vertical boring machine.

[0045] In this embodiment, the boring machine 10 includes a mounting plate 11, a motor 12, a transmission mechanism 13, and a spindle box 14. The motor 12, transmission mechanism 13, and spindle box 14 are all connected to the mounting plate 11. The transmission mechanism 13 includes a transmission belt 131 and a transmission shaft 132. The motor 12 drives the transmission shaft 132 to rotate through the transmission belt 131. When the transmission shaft 132 rotates, it drives the spindle 141 in the spindle box 14 to rotate. Thus, the boring tool can be driven by the spindle 141 to perform boring operations, thereby realizing the boring processing of metal parts. Since the transmission is carried out through the transmission belt 131, the cost is lower compared with the gear transmission in the gearbox in the prior art. Moreover, the replacement process of the transmission belt 131 after wear is simpler, and compared with replacing the gears in the gearbox, it can save maintenance time.

[0046] Figure 2 This is a schematic diagram of an installation plate provided in an embodiment of this application. Figure 2 As shown, the mounting plate 11 includes: a plate body 111, a motor fixing plate 112, and a bearing support 113.

[0047] The motor mounting plate 112 is connected to the first surface of the plate body 111 by welding. The bearing support seat 113 is connected to the first surface of the plate body 111 by bolts. The housing 142 of the spindle box 14 is connected to the second surface of the plate body 111 by bolts. The motor 12 is connected to the motor mounting plate 112 by bolts. The bearing support seat 113 is sleeved on the outside of the transmission shaft 132, so that the transmission shaft 132 is connected to the plate body 111.

[0048] Optionally, the motor mounting plate 112 may include a first through hole 1121, that is, the motor mounting plate 112 is a square or circular tubular structure, and the side of the motor mounting plate 112 includes a receiving groove. When the motor 12 is connected to the motor mounting plate 112, the output end of the motor 12 is located in the first through hole 1121, that is, in the tubular structure. Part of the transmission belt 131 is located in the first through hole 1121 and connected to the output end of the motor 12, and part of it extends out of the motor mounting plate 112 through the receiving groove and is connected to the transmission shaft 132.

[0049] In this embodiment, the mounting plate 11 includes a plate body 111, a motor fixing plate 112, and a bearing support seat 113. The motor fixing plate 112 and the bearing support seat 113 are respectively connected to the plate body 111. The spindle box 14 is connected to the plate body 111. The motor 12 is connected to the motor fixing plate 112. The transmission shaft 132 is located inside the bearing support seat 113. The mounting plate 11 fixes the various parts of the boring equipment 10, which can prevent the relative positions of the motor 12, the transmission shaft 132, and the spindle box 14 from changing during the operation of the boring equipment 10, thus ensuring the normal operation of the boring equipment 10 and reducing safety hazards.

[0050] Figure 3This is a cross-sectional schematic diagram of a transmission shaft provided in an embodiment of this application. For example... Figure 3 As shown, the drive shaft 132 includes a first drive wheel 1321, a bearing 1322, and a spline sleeve 1323.

[0051] The outer surface of the first drive wheel 1321 is connected to the drive belt 131, and the inner surface of the first drive wheel 1321 is connected to the spline sleeve 1323. The inner surface of the bearing 1322 contacts the spline sleeve 1323, and the outer surface of the bearing 1322 contacts the inner surface of the bearing support 113. The bearing support 113 is a circular tubular structure, and the bearing 1322 is located within the inner surface of the tubular structure.

[0052] Optionally, the inner surface of the first transmission wheel 1321 can be an internal spline, and the inner surface of the bearing 1322 can also be an internal spline. The external spline of the spline sleeve 1323 is splined to the internal spline of the first transmission wheel 1321 and the internal spline on the surface of the bearing 1322.

[0053] When motor 12 is running, its output drives the first transmission wheel 1321 to rotate via transmission belt 131. The rotation of the first transmission wheel 1321 drives the spline sleeve 1323 to rotate, which in turn drives the spindle 141 of the spindle box 14 to rotate, thus enabling the boring tool to perform boring operations via the spindle 141. During transmission, because the bearing 1322 is located between the spline sleeve 1323 and the bearing support 113, it acts as a limit, preventing any deviation in the straight line of the spline sleeve 1323's rotation axis, ensuring smooth rotation of the spline sleeve 1323.

[0054] In this embodiment, the transmission shaft 132 includes a first transmission wheel 1321, a bearing 1322, and a spline sleeve 1323. The transmission belt 131 is connected to the outer surface of the first transmission wheel 1321, and the spline sleeve 1323 is connected to the inner surface of the first transmission wheel 1321. The bearing 1322 is sleeved on the outside of the spline sleeve 1323 and located between the spline sleeve 1323 and the bearing support seat 113. The motor 12 can drive the first transmission wheel 1321 to rotate through the transmission belt 131. The first transmission wheel 1321 can drive the spline sleeve 1323 to rotate, thereby driving the spindle 141 in the spindle box 14 to rotate through the spline sleeve 1323, realizing the boring operation by driving the boring tool through the spindle 141. The bearing 1322 can prevent the rotation axis of the spline sleeve 1323 from deviating, ensuring the stability of the transmission.

[0055] Figure 4 This is a cross-sectional schematic diagram of another drive shaft provided in an embodiment of this application. For example... Figure 4As shown, the drive shaft 132 includes two bearings 1322, which are vertically stacked within the bearing support 113. Both bearings 1322 are sleeved on the outside of the spline sleeve 1323 and are located between the spline sleeve 1323 and the bearing support 113.

[0056] Optionally, the two bearings 1322 have the same model and size.

[0057] In this embodiment, the drive shaft 132 includes two bearings 1322, which are stacked inside the bearing support 113 and both bearings 1322 are sleeved on the outside of the spline sleeve 1323. By setting two bearings 1322, the rigidity of the bearing support 113 can be increased, and the support rigidity of the first drive wheel 1321 can be improved, thereby extending the service life of the bearing support 113, the plate 111, the first drive wheel 1321, and the spline sleeve 1323.

[0058] Figure 5 This is a cross-sectional schematic diagram of a mounting plate including a pressure cap, provided in an embodiment of this application. For example... Figure 5 As shown, the mounting plate 11 also includes a pressure cap 114.

[0059] The pressure cap 114 is bolted to the bearing support 113. The pressure cap 114 contacts the upper surface of the bearing support 113, and the lower surface of the bearing support 113 contacts the upper surface of the plate 111. A receiving space is formed between the pressure cap 114 and the bearing support 113. Since the spline sleeve 1323 needs to pass through the bearing support 113 and the mounting plate 11 to connect with the housing 142 located on the other surface of the mounting plate 11, the receiving space is not a sealed space. The pressure cap 114 includes a through hole, through which the spline sleeve 1323 passes and connects to the second drive wheel 123 located above the pressure cap 114. Optionally, the pressure cap 114 contacts the upper surface of the bearing 1322. When two bearings 1322 are included, the pressure cap 114 contacts the upper surface of the upper bearing 1322, restricting the movement of the bearing 1322 in a direction parallel to the rotation axis of the spline sleeve 1323.

[0060] In this embodiment, the mounting plate 11 further includes a pressure cover 114, which is bolted to the bearing support seat 113. The bearing 1322 is located in the accommodating space formed by the pressure cover 114 and the bearing support seat 113. The pressure cover 114 can restrict the movement of the bearing 1322 in the direction parallel to the axis of the spline sleeve 1323, which can prevent the bearing 1322 from being displaced when the boring equipment 10 is running at high speed, and can also prevent the bearing 1322 from flying out of the bearing support seat 113, thus reducing safety hazards.

[0061] Figure 6 This is a cross-sectional schematic diagram of a spindle box provided in an embodiment of this application. For example... Figure 6 As shown, the first end of the spindle 141 is located inside the housing 142.

[0062] The first end of the spindle 141 includes a blind hole 1411, the inner surface of which is an internal spline. The second end of the spline sleeve 1323 is inserted into the blind hole 1411, allowing the spline sleeve 1323 to be accommodated within it. The outer surface of the spline sleeve 1323 is an external spline. When the spline sleeve 1323 is accommodated within the blind hole 1411, the external spline of the spline sleeve 1323 and the internal spline of the blind hole 1411 are splinedly connected. The second end of the spindle 141 holds a boring tool. When the spindle 141 rotates, it drives the boring tool to rotate, performing boring operations on the metal part.

[0063] When the motor 12 is running, the output end of the motor 12 drives the first transmission wheel 1321 to rotate through the transmission belt 131. When the first transmission wheel 1321 rotates, it drives the spline sleeve 1323 to rotate through the external spline. When the spline sleeve 1323 rotates, it drives the spindle 141 of the spindle box 14 to rotate through the internal spline, so that the boring tool is driven by the spindle 141 to perform boring operation.

[0064] In this embodiment, the first end of the spindle 141 is disposed inside the housing 142. The first end of the spindle 141 includes a blind hole 1411, and a spline sleeve 1323 is accommodated in the blind hole 1411. Through the spline connection between the outer spline of the spline sleeve 1323 and the inner spline of the blind hole 1411, the spindle 141 can be rotated relative to the housing 142 when the spline sleeve 1323 rotates. Thus, the spindle 141 drives the boring tool to perform boring operations, thereby realizing the boring process of metal parts. Since the spindle 141 and the spline sleeve 1323 are connected by splines, the multi-tooth structure can make the load evenly distributed, and the contact area between the transmission shaft 132 and the spindle 141 is large, so as to transmit a larger torque.

[0065] Figure 7 This is a cross-sectional schematic diagram of an electric motor provided in an embodiment of this application. For example... Figure 7 As shown, the motor 12 includes: a motor body 121, a motor mounting plate 122, and a second transmission wheel 123.

[0066] The motor mounting plate 122 is connected to the motor body 121. The motor mounting plate 122 is provided with bolt holes and is connected to the motor fixing plate 112 by bolts. The second transmission wheel 123 is connected to the output shaft of the motor body 121. Optionally, the second transmission wheel 123 can be connected to the output shaft of the motor body 121 by a key and bolts.

[0067] The motor body 121 can run when it receives a running signal. It drives the second transmission wheel 123 to rotate through the output shaft, and drives the first transmission wheel 1321 to rotate through the second transmission wheel 123 and the transmission belt 131. When the first transmission wheel 1321 rotates, it drives the spline sleeve 1323 to rotate through the external spline. When the spline sleeve 1323 rotates, it drives the spindle 141 of the spindle box 14 to rotate through the internal spline, so that the boring tool can be driven by the spindle 141 to perform boring operations.

[0068] Optionally, Figure 8 This is a schematic diagram of a transmission wheel provided in an embodiment of this application. (As shown...) Figure 8 As shown, the first transmission wheel 1321 includes multiple second through holes 1324. By providing multiple second through holes 1324 on the first transmission wheel 1321, the weight of the first transmission wheel 1321 can be reduced. When the motor 12 stops running, the braking inertia of the first transmission wheel 1321 can be reduced, thereby reducing downtime and improving processing efficiency. The second transmission wheel 123 can also be... Figure 8 The relevant structure of the first transmission wheel 1321 shown in the figure will not be described in detail here.

[0069] In this embodiment, the motor 12 includes a motor body 121, a motor mounting plate 122, and a second transmission wheel 123. The second transmission wheel 123 is connected to the output shaft of the motor body 121. The motor mounting plate 122 can fix the motor body 121 on the motor mounting plate 112, thereby mounting the motor 12 on the plate 111. This prevents changes in the relative position between the motor 12 and the transmission shaft 132 during operation. Since the motor body 121 drives the first transmission wheel 1321 to rotate through the second transmission wheel 123 and the transmission belt 131, the cost is lower compared to the gear transmission in the gearbox in the prior art. Furthermore, the replacement process of the transmission belt 131 after wear is simpler, saving maintenance time compared to replacing the gears in the gearbox.

[0070] In one possible implementation, the motor body 121 can be a three-phase asynchronous motor.

[0071] In this embodiment, the motor body 121 is a three-phase asynchronous motor. Three-phase asynchronous motors have advantages such as simple structure, robustness and durability, low cost, low maintenance, high reliability, good efficiency, strong environmental adaptability, and excellent speed regulation performance provided by modern frequency conversion technology.

[0072] Figure 9 This is a schematic diagram of a motor mounting plate provided in an embodiment of this application. Figure 9 As shown, the bolt holes on the motor mounting plate 122 can be oblong bolt holes.

[0073] Since the motor mounting plate 122 is fixedly connected to the motor body 121, and the second transmission wheel 123 is fixedly connected to the output shaft of the motor body 121, when the bolt holes on the motor mounting plate 122 are oblong bolt holes, since the motor mounting plate 122 is connected to the motor fixing plate 112 by bolts, the relative position between the motor mounting plate 122 and the motor fixing plate 112 can be adjusted through the oblong bolt holes, thereby adjusting the relative position between the motor body 121 and the motor fixing plate 112. Furthermore, since the motor fixing plate 112 is welded to the plate 111, adjusting the relative position between the motor body 121 and the motor fixing plate 112 is equivalent to adjusting the relative position between the motor body 121 and the transmission shaft 132, thereby adjusting the tension of the transmission belt 131 between the first transmission shaft 132 and the second transmission shaft 132.

[0074] In this embodiment, the bolt holes on the motor mounting plate 122 can be oblong bolt holes. The distance between the motor body 121 and the spline sleeve 1323 can be adjusted through the oblong bolt holes, thereby adjusting the distance between the first drive shaft 132 and the second drive shaft 132, and adjusting the tension of the drive belt 131. By adjusting the tension of the drive belt 131, the transmission efficiency of the drive belt 131 can be guaranteed, and the drive belt 131 can be guaranteed to be free of abnormal noise or vibration during transmission.

[0075] In one possible implementation, such as Figure 5 As shown, the first transmission wheel 1321 and the spline sleeve 1323 are connected by a snap ring 1325.

[0076] In this embodiment, the first transmission wheel 1321 and the spline sleeve 1323 are connected by a snap ring 1325, which can prevent the first transmission wheel 1321 from disengaging from the spline sleeve 1323 during transmission, ensuring the normal operation of the equipment and reducing safety hazards.
