DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, an L-shaped workpiece grinding mechanism in one embodiment of the present invention includes a grinding table 1 and a grinding mechanism 2.

[0034] Among them, the driving motor is installed in the grinding table 1, and the driving motor is used to provide continuous rotational power for driving the crank 201 to rotate. The selection of the driving motor needs to consider power and speed to meet different grinding requirements.

[0035] In addition, a groove 101 is cut on the grinding table 1, and the output end of the driving motor is arranged in the groove 101. The bottom wall of the groove 101 is provided with a cam groove 102. The shape of the cam groove 102 is as follows: Figure 1 and Figure 4 As shown, the cam groove 102 is used to guide the movement of the connecting rod 206. Through the guidance of the cam groove 102, the connecting rod 206 can drive the grinding head 208 to move along a predetermined inner semicircular arc track so as to accurately grind the L-shaped workpiece.

[0036] Specifically, a control panel 103 is installed on the polishing table 1 , the driving motor is electrically connected to the control panel 103 , and the control panel 103 is used to control the operation of the driving motor.

[0037] like Figures 1 to 6 As shown, a pair of brackets 104 are installed on the top surface of the grinding table 1. The brackets 104 are used to install the clamping plate 107. A screw rod 105 is rotatably connected inside the bracket 104. By rotating the screw rod 105, the height of the mounting plate 106 and the clamping plate 107 can be adjusted to fix or release the L-shaped workpiece.

[0038] Among them, a mounting plate 106 is slidably provided in the bracket 104, and the mounting plate 106 is threadedly connected to the screw rod 105. The mounting plate 106 is used to connect the clamping plate 107. At the same time, when the screw rod 105 rotates, the mounting plate 106 is affected by the thread and moves up and down in the bracket 104.

[0039] In addition, a clamping plate 107 is fixedly connected to the mounting plate 106. The clamping plate 107 is used to clamp and fix the L-shaped workpiece so that the L-shaped workpiece is not easily displaced during grinding, thereby ensuring the grinding quality of the L-shaped workpiece.

[0040] Specifically, a pair of support pads are mounted on the top surface of the grinding table 1, and each of the support pads corresponds to the pair of pressure plates 107. The support pads are used to support the L-shaped workpiece so that the grinding head 208 can grind the inner side of the L-shaped workpiece. At the same time, the support pads also prevent the L-shaped workpiece from shifting during grinding, thereby ensuring the fixed stability of the L-shaped workpiece.

[0041] In addition, a plurality of protrusions are provided on the bottom wall of the pressing plate 107. The protrusions and the support pads are made of rubber material, which is used to increase the fixing effect of the L-shaped workpiece without causing hard squeezing of the L-shaped workpiece.

[0042] like Figures 1 to 6 As shown, the grinding mechanism 2 is installed in the groove 101. The grinding mechanism 2 is used to perform cyclic grinding on the L-shaped workpiece, thereby reducing manual participation. It can not only improve the grinding efficiency of the L-shaped workpiece and reduce the manual burden, but also reduce the error caused by manual grinding and ensure the grinding quality of the L-shaped workpiece.

[0043] The grinding mechanism 2 includes a crank 201 connected to the delivery end of the driving motor. The crank 201 is used to convert the rotational motion of the driving motor into the reciprocating motion of the connecting rod 206.

[0044] In addition, a connecting sleeve 202 is fixedly connected to the crank 201, and the connecting sleeve 202 is sleeved on the output end of the drive motor. A fastening bolt 203 is threadedly connected to the connecting sleeve 202. The crank 201 can be fixed to the output end of the drive motor through the mutual cooperation between the connecting sleeve 202 and the fastening bolt 203.

[0045] Specifically, an avoidance groove 204 is provided at one end of the crank 201 away from the connecting sleeve 202 , so that the connecting rod 206 is not likely to come into contact with the crank 201 during rotation.

[0046] In addition, a fixing rod 205 is fixedly connected to the avoidance groove 204 , and the connecting rod 206 is sleeved on the fixing rod 205 . The connecting rod 206 can be installed on the fixing rod 205 through the cooperation between the fixing rod 205 and the limiting nut 207 .

[0047] like Figures 1 to 6As shown, the crank 201 is connected to a connecting rod 206 , which is used to connect the crank 201 and the grinding head 208 , and the grinding head 208 is driven to move along a specific trajectory by the rotation of the crank 201 .

[0048] Among them, the connecting rod 206 is equipped with a cam, and the cam is arranged in the cam groove 102. When the crank 201 rotates, the connecting rod 206 drives the connecting rod 206 to move. Since the connecting rod 206 is equipped with a cam and the cam is arranged in the cam groove 102, the connecting rod 206 will move along a specific trajectory.

[0049] In addition, a limiting nut 207 is threadedly connected to the fixing rod 205, and the connecting rod 206 is arranged between the limiting nut 207 and the bottom wall of the avoidance groove 204 to limit the connecting rod 206 so that the connecting rod 206 is not easily separated from the fixing rod 205.

[0050] Specifically, a wheel-shaped grinding head 208 is rotatably connected to the connecting rod 206 to thoroughly grind the inside of the L-shaped workpiece, ensuring uniform grinding. The grinding head 208 contacts and grinds the L-shaped workpiece. The material and shape of the grinding head 208 are selected based on the material and grinding requirements of the L-shaped workpiece. Guided by the connecting rod 206 and the cam groove 102, the grinding head 208 evenly grinds the surface of the L-shaped workpiece, ensuring a high-quality finish.

[0051] This application is applicable to a variety of L-shaped workpieces requiring precise grinding of their inner semicircular arcs, such as mechanical parts, automotive accessories, and aerospace components. It offers significant advantages in improving machining accuracy and efficiency, making it suitable for mass production and high-precision grinding tasks. By adjusting the length of crank 201, the length of connecting rod 206, and the shape of cam groove 102, it can accommodate L-shaped workpieces of varying sizes and shapes.

[0052] When in use, the L-shaped workpiece is placed on the grinding table 1, and the L-shaped workpiece can be fixed by the cooperation between the pressing plate 107 and the support pad. Figure 1 The status shown.

[0053] The drive motor is operated to rotate the crank 201, which in turn rotates the connecting rod 206. Because the connecting rod 206 is equipped with a cam that is positioned within the cam slot 102, the connecting rod 206 moves along a specific trajectory. The connecting rod 206 can drive the grinding head 208 to move synchronously, and the grinding head 208 can contact and grind the L-shaped workpiece during movement.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
