Description

Technical Field

[0001] This application relates to the field of grinding machine technology, and in particular to a grinding wheel assembly mechanism for a grinding machine. Background Technology

[0002] Grinding machines can be used to roughen circuit boards through grinding. The grinding rollers, mounted on a shaft, roughen the circuit board. In existing technology, the rollers are held in place by a front and rear sleeve, which are fitted onto the shaft and rotate with it. The grinding rollers are driven to rotate by the front and rear sleeves, thus roughening the circuit board. Disassembling the grinding rollers and shaft requires removing the threaded screws, which requires specialized tools and is complex and cumbersome. Furthermore, existing technology often uses copper nuts to lock the front sleeves onto the shaft, leaving the copper nuts exposed. During the grinding process, water is often sprayed throughout, exposing the copper nuts to a high-humidity environment, which can cause rust and make disassembly difficult. Additionally, copper powder is generated during grinding, which can become trapped inside the copper nuts, further hindering disassembly. Utility Model Content

[0003] To facilitate quick and easy assembly and disassembly of the grinding roller, and to better protect the assembly and disassembly parts, this application proposes a grinding roller shaft assembly mechanism for a grinding plate machine.

[0004] The technical solution provided in this application for a grinding wheel shaft assembly mechanism for a grinding plate machine is as follows: A grinding wheel shaft assembly mechanism for a grinding machine includes: a grinding wheel shaft, a grinding wheel, a drive unit, and a fixing unit. The output end of the drive unit is connected to one end of the grinding wheel shaft. The grinding wheel shaft is provided with a front top sleeve and a rear top sleeve. The front top sleeve is sleeved on the end of the grinding wheel shaft away from the drive unit, and the rear top sleeve is fixed on the end of the grinding wheel shaft close to the drive unit. The ends of the grinding wheel abut against the front top sleeve and the rear top sleeve, respectively.

[0005] The fixing unit includes a first bearing housing, a grinding wheel shaft guide sleeve, a first nut, and a second nut. The first bearing housing has a mounting hole, through which the grinding wheel shaft passes. The grinding wheel shaft guide sleeve is fitted onto the grinding wheel shaft and located within the mounting hole. The second nut is fitted onto the grinding wheel shaft guide sleeve, which is sandwiched between the first nut and the second nut. The second nut and the grinding wheel shaft guide sleeve are connected and engaged. The grinding wheel shaft guide sleeve and the grinding wheel shaft are connected and engaged, and are located on opposite sides of the first bearing housing. The first nut and the second nut are suitable for fixing the grinding wheel shaft guide sleeve onto the first bearing housing.

[0006] The above technical solution uses a front top sleeve and a rear top sleeve to press the grinding wheel against the grinding wheel shaft. The front top sleeve and the rear top sleeve can not only fix the grinding wheel to prevent it from moving left or right, but also transmit the rotation of the grinding wheel shaft to the grinding wheel, so that the grinding wheel rotates with the grinding wheel shaft. Furthermore, the fixing unit makes it easier for workers to install or remove the grinding wheel from the grinding wheel shaft. The grinding wheel shaft guide sleeve can also provide radial positioning and axial limiting for the grinding wheel shaft.

[0007] Preferably, the end of the grinding wheel shaft away from the drive unit is provided with a connecting mounting groove and a blind hole. A push rod is slidably arranged in the blind hole. The push rod can move along the length direction of the grinding wheel shaft. A slider is slidably arranged in the mounting groove. The slider is located between the front top sleeve and the push rod, and is suitable for driving the push rod to press against the slider so that the slider is pressed against the front top sleeve.

[0008] The above technical solution can improve the clamping force of the front top sleeve on the grinding wheel by using the push rod, so that the grinding wheel can be better fixed between the front and rear top sleeves. When the front and rear top sleeves rotate, they can better drive the grinding wheel to rotate, which is beneficial to improving the stability of the front and rear top sleeves driving the grinding wheel to rotate.

[0009] Preferably, the end of the push rod away from the slider is provided with a screw, and the end of the blind hole away from the drive unit is provided with an internal thread, and the screw is threadedly connected to the blind hole.

[0010] The above technical solution facilitates the operation of the push rod by the screw, and the locking force of the screw is sufficient to prevent the grinding wheel from loosening due to insufficient clamping force of the push rod against the front top sleeve. In other words, driving the push rod to clamp the front top sleeve and the grinding wheel with the screw helps to improve the stability of the grinding wheel.

[0011] Preferably, the end of the front top sleeve away from the grinding wheel is provided with a groove, the end of the slider away from the push rod extends into the groove and is limited and matched with the groove, and the end of the front top sleeve near the middle of the grinding wheel shaft is provided with a first guide slope.

[0012] The above technical solution, with the slider located in the groove, helps to prevent the front top sleeve from loosening. When the grinding wheel shaft rotates, it can drive the front top sleeve to rotate together, thereby transmitting the rotation to the grinding wheel. This ensures that the rotation speed of the front top sleeve and the grinding wheel shaft are synchronized. On the other hand, the first guide slope allows the operator to directly install the front top sleeve. The first guide slope plays a guiding role during installation. The operator only needs to place the front top sleeve against the grinding wheel and then tighten it with the push rod.

[0013] Preferably, a first bearing is provided in the mounting hole, and the first bearing is sleeved on the grinding wheel shaft guide sleeve.

[0014] Through the above technical solution, the first bearing can provide an auxiliary function for the grinding wheel shaft guide sleeve when the grinding wheel shaft rotates, which is beneficial for the grinding wheel shaft guide sleeve to rotate with the grinding wheel shaft. Furthermore, the first bearing seat can be used to install the grinding wheel shaft on the fixing device of the external device.

[0015] Preferably, one end of the rear top sleeve is provided with a second guide slope, and the other end is provided with a clamping block. The clamping block is ring-shaped and fits against and limits the end wall of the grinding wheel.

[0016] Through the above technical solution, the second guide slope can guide the grinding wheel to make its axis coincide with the axis of the rear top sleeve. This is beneficial because when the rear top sleeve rotates and drives the grinding wheel to rotate, the rotating grinding wheel will not be relatively offset. In other words, it ensures that the rear top sleeve and the grinding wheel rotate around the same axis. The locking block and the grinding wheel stop and limit the movement, which can further improve the stability of the grinding wheel.

[0017] Preferably, the grinding wheel shaft is provided with a positioning hole, and the rear top sleeve is fixed on the grinding wheel shaft by a set screw passing through the positioning hole.

[0018] The above technical solution allows the rear top sleeve to be fixed to the grinding wheel shaft by inserting a set screw into the positioning hole. This not only helps to tighten the grinding wheel against the rear top sleeve and improve stability, but also helps to drive the rear top sleeve to rotate when the grinding wheel shaft rotates, ensuring that the rotation speed of the rear top sleeve is consistent with the rotation speed of the grinding wheel shaft.

[0019] Preferably, a second bearing housing is provided on one end of the grinding wheel shaft near the drive unit, and a second bearing is provided inside the second bearing housing, which is sleeved on the grinding wheel shaft.

[0020] Through the above technical solution, the second bearing housing can fix the grinding wheel shaft on the external fixing device, thereby improving stability. Moreover, the second bearing can also provide auxiliary function for the rotation of the grinding wheel shaft, which is beneficial to the rotation of the grinding wheel shaft.

[0021] Preferably, the drive unit includes a drive motor and a pulley mechanism, with the output end of the drive motor connected to one end of the pulley mechanism and the other end of the pulley mechanism connected to one end of the grinding wheel shaft.

[0022] The above technical solution, which uses a drive motor to drive a pulley mechanism and then uses the pulley mechanism to drive the grinding wheel shaft to rotate, avoids the impact load caused by the drive motor directly driving the grinding wheel shaft to rotate, thus better protecting the grinding wheel shaft.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The grinding wheel is pressed against the grinding wheel shaft by the front and rear top sleeves. The front and rear top sleeves can not only fix the grinding wheel to prevent it from moving left and right, but also transmit the rotation of the grinding wheel shaft to the grinding wheel, so that the grinding wheel rotates with the grinding wheel shaft. In addition, the fixing unit makes it easier for workers to install or remove the grinding wheel from the grinding wheel shaft. The grinding wheel shaft guide sleeve can radially position the grinding wheel shaft and also axially limit it. 2. The push rod can increase the clamping force of the front push sleeve on the grinding wheel, so that the grinding wheel can be better fixed between the front push sleeve and the rear push sleeve. When the front push sleeve and the rear push sleeve rotate, they can drive the grinding wheel to rotate better, which is beneficial to improving the stability of the front push sleeve and the rear push sleeve driving the grinding wheel to rotate. 3. The slider is located in the groove, which helps to prevent the front top sleeve from loosening. When the grinding wheel shaft rotates, it can drive the front top sleeve to rotate together, thereby transmitting the rotation to the grinding wheel. This ensures that the front top sleeve and the grinding wheel shaft rotate at the same speed. On the other hand, the first guide slope makes it easy for the operator to directly install the front top sleeve. The first guide slope plays a guiding role during installation. The operator only needs to place the front top sleeve against the grinding wheel and then tighten it with the push rod. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] This application discloses a grinding wheel shaft assembly mechanism for a grinding plate machine. The grinding wheel shaft assembly mechanism allows for simple and quick assembly and disassembly of the grinding wheel, and better protects the disassembled parts.

[0028] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 According to the embodiments of this application, a grinding wheel shaft assembly mechanism for a grinding machine includes: a grinding wheel shaft 100, a grinding wheel 200, a drive unit, and a fixing unit 300. The output end of the drive unit is connected to one end of the grinding wheel shaft 100. The grinding wheel shaft 100 is provided with a front top sleeve 110 and a rear top sleeve 120. The front top sleeve 110 is sleeved on the end of the grinding wheel shaft 100 away from the drive unit, and the rear top sleeve 120 is fixed on the end of the grinding wheel shaft 100 close to the drive unit. The ends of the grinding wheel 200 abut against the front top sleeve 110 and the rear top sleeve 120 respectively.

[0029] The fixing unit 300 includes a first bearing seat 310, a grinding wheel shaft guide sleeve 320, a first nut 330, and a second nut 340. The first bearing seat 310 has a mounting hole, through which the grinding wheel shaft 100 passes. The grinding wheel shaft guide sleeve 320 is sleeved on the grinding wheel shaft 100 and located in the mounting hole. The second nut 340 is sleeved on the grinding wheel shaft guide sleeve 320 and sandwiched between the first nut 330 and the second nut 340. The second nut 340 is connected and engaged with the grinding wheel shaft guide sleeve 320 and the grinding wheel shaft 100, and is located on both sides of the first bearing seat 310. The first nut 330 and the second nut 340 are suitable for fixing the grinding wheel shaft guide sleeve 320 on the first bearing seat 310.

[0030] In this embodiment, the grinding roller 200 is installed on the grinding roller shaft 100. First, the rear top sleeve 120 is fixed to one end of the grinding roller shaft 100. Then, the grinding roller 200 is fitted onto the grinding roller shaft 100, with one end of the grinding roller 200 abutting against the rear top sleeve 120. Next, the front top sleeve 110 is fitted onto the grinding roller shaft 100 from the other end, with the front top sleeve 110 abutting against the grinding roller shaft 100. The grinding roller 200 is tightly installed on the grinding roller shaft 100 by the front top sleeve 110 and the rear top sleeve 120. Then, the grinding roller shaft guide sleeve 320 is fitted onto the end of the grinding roller shaft 100 near the front top sleeve 110. Next, the first bearing seat 310 is fitted onto the grinding roller shaft guide sleeve 320. Finally, the first nut 330 and the second nut 340 are locked in sequence, so that the grinding roller shaft guide sleeve 320 is locked onto the grinding roller shaft 100, thus completing the installation.

[0031] To remove the grinding roller 200 from the grinding roller shaft 100, first loosen the second nut 340 and the first nut 330 in sequence, then remove the first bearing seat 310 from the grinding roller shaft 100, then remove the grinding roller shaft guide sleeve 320 from the grinding roller shaft 100, and finally remove the front top sleeve 110. This will allow you to remove the grinding roller 200 from the grinding roller shaft 100.

[0032] In practical applications, the grinding roller 200 is mounted on the grinding roller shaft 100. The grinding roller shaft 100 is driven to rotate by the drive unit, which in turn drives the front top sleeve 110 and the rear top sleeve 120 to rotate, thereby driving the grinding roller 200 to rotate. The grinding roller 200 performs grinding and roughening treatment on the surface of the circuit board. When it is necessary to maintain and replace the grinding roller 200, the grinding roller 200 can be removed simply by following the disassembly steps. No special tools are involved; only an Allen wrench and a socket wrench are needed to complete the entire disassembly and assembly process.

[0033] Through the above technical solution, the grinding roller 200 is pressed against the grinding roller shaft 100 by the front top sleeve 110 and the rear top sleeve 120. The front top sleeve 110 and the rear top sleeve 120 can not only fix the grinding roller 200 to prevent the grinding roller 200 from moving left and right, but also transmit the rotation of the grinding roller shaft 100 to the grinding roller 200, so that the grinding roller 200 rotates with the grinding roller shaft 100. Furthermore, the fixing unit 300 makes it easier for workers to install or remove the grinding roller 200 from the grinding roller shaft 100. The grinding roller shaft guide sleeve 320 can radially position the grinding roller shaft 100 and also axially limit it.

[0034] Reference Figure 3 and Figure 4The grinding wheel shaft 100 is provided with a connecting mounting groove 130 and a blind hole 140 at one end away from the drive unit. A push rod 141 is slidably disposed in the blind hole 140. The push rod 141 can move along the length direction of the grinding wheel shaft 100. A slider 131 is slidably disposed in the mounting groove 130. The slider 131 is located between the front top sleeve 110 and the push rod 141, and is suitable for driving the push rod 141 to press against the slider 131 so that the slider 131 is pressed against the front top sleeve 110.

[0035] With the above design, the operator can move the push rod 141 along the length of the grinding wheel shaft 100 towards the front top sleeve 110, push the slider 131 so that the slider 131 and the front top sleeve 110 abut against each other, thereby pressing the grinding wheel 200 against the rear top sleeve 120, thus fixing the grinding wheel 200 between the front top sleeve 110 and the rear top sleeve 120. When it is necessary to disassemble the grinding wheel 200, the operator can move the push rod 141 along the length of the grinding wheel shaft 100 away from the front top sleeve 110, thereby loosening the front top sleeve 110, which makes it convenient for the operator to remove the front top sleeve 110 and the grinding wheel 200 from the grinding wheel shaft 100.

[0036] Through the above technical solution, the push rod 141 can increase the clamping force of the front top sleeve 110 on the grinding roller 200, so that the grinding roller 200 can be better fixed between the front top sleeve 110 and the rear top sleeve 120. When the front top sleeve 110 and the rear top sleeve 120 rotate, they can better drive the grinding roller 200 to rotate, which is conducive to improving the stability of the front top sleeve 110 and the rear top sleeve 120 driving the grinding roller 200 to rotate.

[0037] Reference Figures 2-5 The end of the push rod 141 away from the slider 131 is provided with a screw 142, and the end of the blind hole 140 away from the drive unit is provided with an internal thread. The screw 142 is threadedly connected to the blind hole 140.

[0038] In this embodiment, the operator can drive the push rod 141 to move along the length of the grinding wheel shaft 100 by rotating the screw 142. When the screw 142 is rotated clockwise, the screw 142 will move towards the front top sleeve 110, thereby driving the push rod 141 to press the front top sleeve 110 against the grinding wheel 200, and the grinding wheel 200 against the rear top sleeve 120. When the screw 142 is rotated counterclockwise, the screw 142 will move away from the front top sleeve 110, thereby driving the push rod 141 to loosen the front top sleeve 110, thus facilitating the disassembly of the front top sleeve 110 and the grinding wheel 200.

[0039] Through the above technical solution, the screw 142 facilitates the operation of the push rod 141 by the operator, and the locking force of the screw 142 is sufficient to prevent the grinding wheel 200 from becoming loose due to insufficient clamping force of the push rod 141 against the front top sleeve 110. In other words, driving the push rod 141 to clamp the front top sleeve 110 and the grinding wheel 200 by the screw 142 helps to improve the stability of the grinding wheel 200.

[0040] Reference Figure 1 and Figure 2 The front top sleeve 110 has a groove 111 on the end away from the grinding wheel 200. The end of the slider 131 away from the top rod 141 extends into the groove 111 and is limited to the groove 111. The end of the front top sleeve 110 near the middle of the grinding wheel shaft 100 has a first guide slope 112.

[0041] In the above design, when installing the front top sleeve 110, the front top sleeve 110 is fitted onto the grinding wheel shaft 100, and a part of the front top sleeve 110 can be easily inserted into the grinding wheel 200 through the first guide slope 112. Specifically, when the grinding wheel 200 and the front top sleeve 110 are pressed together, one end of the grinding wheel 200 will abut against the first guide slope 112. On the other hand, when the push rod 141 presses the slider 131 against the front top sleeve 110, one end of the slider 131 is located in the groove 111.

[0042] With the above technical solution, the slider 131 is located in the groove 111, which helps to prevent the front top sleeve 110 from loosening. When the grinding wheel shaft 100 rotates, it can drive the front top sleeve 110 to rotate together, thereby transmitting the rotation to the grinding wheel 200. This ensures that the rotation speed of the front top sleeve 110 and the grinding wheel shaft 100 is synchronized. On the other hand, the first guide slope 112 makes it convenient for the staff to directly install the front top sleeve 110. The first guide slope 112 plays a guiding role during installation. The staff only needs to place the front top sleeve 110 against the grinding wheel 200 and then tighten it with the push rod 141.

[0043] Reference Figure 3 and Figure 5 The mounting hole is provided with a first bearing 350, which is sleeved on the grinding wheel shaft guide sleeve 320.

[0044] Through the above design, the first bearing 350 can assist the grinding wheel shaft 100 to rotate. When the grinding wheel shaft 100 rotates, the grinding wheel shaft guide sleeve 320 will rotate accordingly. At this time, the first bearing 350 plays an auxiliary role, which is conducive to the rotation of the grinding wheel shaft guide sleeve 320.

[0045] Through the above technical solution, the first bearing 350 can provide an auxiliary function for the grinding wheel shaft guide sleeve 320 when the grinding wheel shaft 100 rotates, which is beneficial for the grinding wheel shaft guide sleeve 320 to rotate with the grinding wheel shaft 100, and the first bearing seat 310 can install the grinding wheel shaft 100 on the fixing device of the external device.

[0046] Reference Figure 3 The rear top sleeve 120 has a second guide slope 121 at one end and a pressing block 122 at the other end. The pressing block 122 is ring-shaped and fits against and limits the end wall of the grinding roller 200.

[0047] Through the above design, the abutting block 122 and the end wall of the grinding roller 200 abut against each other, which helps to improve the stability of the grinding roller 200. When the worker installs the grinding roller 200, he only needs to press the grinding roller 200 against the rear top sleeve 120. The second guide slope 121 can guide the grinding roller 200 to the position where the axis of the grinding roller 200 and the axis of the rear top sleeve 120 coincide.

[0048] Through the above technical solution, the second guide slope 121 can guide the grinding roller 200 so that its axis coincides with the axis of the rear top sleeve 120. This is beneficial because when the rear top sleeve 120 rotates and drives the grinding roller 200 to rotate, the rotating grinding roller 200 will not be relatively offset. In other words, it ensures that the rear top sleeve 120 and the grinding roller 200 rotate around the same axis. The abutting block 122 and the grinding roller 200 stop and limit each other, which can further improve the stability of the grinding roller 200.

[0049] Reference Figure 3 The grinding wheel shaft 100 is provided with a positioning hole 150, and the rear top sleeve 120 is fixed on the grinding wheel shaft 100 by a set screw passing through the positioning hole 150.

[0050] In this embodiment, the rear top sleeve 120 can be fixed to the grinding wheel shaft 100 by passing a set screw through the positioning hole 150. Then, the grinding wheel 200 is pressed against the rear top sleeve 120, and the front top sleeve 110 and the grinding wheel shaft guide sleeve 320 are installed in sequence to complete the installation. It should be noted that the set screw is not shown in the figure.

[0051] With the above technical solution, the rear top sleeve 120 can be fixed on the grinding wheel shaft 100 by means of the set screw passing through the positioning hole 150. This not only helps to press the grinding wheel 200 against the rear top sleeve 120 and improve stability, but also helps to drive the rear top sleeve 120 to rotate when the grinding wheel shaft 100 rotates, ensuring that the rotation speed of the rear top sleeve 120 is consistent with the rotation speed of the grinding wheel shaft 100.

[0052] Reference Figure 1 and Figure 6A second bearing seat 400 is provided on one end of the grinding wheel shaft 100 near the drive unit, and a second bearing 410 is provided inside the second bearing seat 400. The second bearing 410 is sleeved on the grinding wheel shaft 100.

[0053] In the above design, the second bearing 410 can provide assistance for the rotation of the grinding wheel shaft 100, while the second bearing housing 400 can be used to mount the grinding wheel shaft 100 on the external device.

[0054] Through the above technical solution, the second bearing seat 400 can fix the grinding wheel shaft 100 on the external fixing device, thereby improving stability. Moreover, the second bearing 410 can also provide auxiliary function for the rotation of the grinding wheel shaft 100, which is beneficial to the rotation of the grinding wheel shaft 100.

[0055] As a preferred embodiment, the drive unit includes a drive motor and a pulley mechanism. The output end of the drive motor is connected to one end of the pulley mechanism, and the other end of the pulley mechanism is connected to one end of the grinding wheel shaft 100.

[0056] With the above design, the drive motor can drive the pulley mechanism to rotate, so that the pulley mechanism transmits the rotation to the grinding wheel shaft 100, thereby driving the grinding wheel shaft 100 to rotate. It should be noted that the drive unit is not shown in the figure.

[0057] The above technical solution, by driving the pulley mechanism with a drive motor and then transmitting the rotation of the grinding shaft 100 through the pulley mechanism, avoids the impact load caused by the drive motor directly driving the grinding shaft 100 to rotate, thus better protecting the grinding shaft 100.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, or shape of this application should be included within the scope of protection of this application.
