Description

Technical Field

[0001] This utility model relates to the technical field of grinding blade clamping devices, and in particular to a clamping device for grinding blades of an external cylindrical grinding machine. Background Technology

[0002] In the machinery manufacturing industry, blade grinding is a highly precise machining process, making the selection of appropriate grinding tools crucial. When grinding slicing machine blades using an external cylindrical grinder, stable blade clamping is paramount. Furthermore, the blade reference point must be concentric with the grinder spindle and perpendicular to the worktable to ensure the grinding angle matches the original grinding angle. Inconsistent grinding angles will negatively impact blade life and slicing quality.

[0003] In existing technologies, insert clamping typically involves first using a jig to hold the insert, then securing the jig to the grinding machine with bolts, or directly fixing the insert to a jig on the grinding machine to achieve positioning and clamping. However, these methods cannot guarantee that the insert reference point is concentric with the grinding machine spindle, resulting in poor grinding performance. Furthermore, after prolonged use, the jigs may loosen, affecting the clamping effect and leading to poor clamping stability. Therefore, there is a need to develop a clamping device for grinding inserts on cylindrical grinding machines. Utility Model Content

[0004] The purpose of this application is to provide a clamping device for grinding inserts on a cylindrical grinding machine, which aims to solve the technical problems of poor clamping stability and poor grinding effect of existing insert clamps.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A clamping device for grinding blades on an external cylindrical grinding machine is provided, comprising a first clamping member and a second clamping member. The first clamping member is provided with a fixing rod, one end of which is provided with a first fixing plate. A positioning platform is provided at the end of the first fixing plate away from the fixing rod, and a first fastening rod is provided at the end of the positioning platform away from the fixing rod. The grinding blade is sleeved on the positioning platform. The second clamping member is provided with a second fixing plate, one end of which is provided with a second fastening rod. A through hole is provided on the second fixing plate, penetrating both the second fixing plate and the second fastening rod. The through hole is threadedly connected to the first fastening rod so that the first fixing plate and the second fixing plate move closer together to clamp the grinding blade.

[0006] In one embodiment, the fixing rod is configured as a tapered handle with a small diameter at one end and a large diameter at the other end, and the first fixing disc is disposed at the large diameter end of the fixing rod.

[0007] In one embodiment, the smaller diameter end of the fixing rod is provided with a fixing groove, the fixing groove is coaxially arranged with the fixing rod, and the inner wall of the fixing groove is provided with threads.

[0008] In one embodiment, the fixing rod, the first fixing plate, the positioning platform, and the first fastening rod are all coaxially arranged.

[0009] In one embodiment, the end of the first fixing plate near the fixing rod is chamfered.

[0010] In one embodiment, the second fastening rod is configured as a hexagonal square.

[0011] In one embodiment, the second fixing plate, the second fastening rod, and the through hole are all coaxially arranged.

[0012] In one embodiment, the outer wall of the first fastening rod is provided with an external thread, and the inner wall of the through hole is provided with an internal thread. The through hole and the first fastening rod are threadedly connected by the external thread and the internal thread.

[0013] In one embodiment, the end of the second fixing plate near the second fastening rod is provided with a chamfer.

[0014] This invention provides a clamping device for grinding inserts on a cylindrical grinding machine.

[0031] Please see Figure 1 This is a schematic diagram of a clamping device for grinding blades of an external cylindrical grinding machine according to an embodiment of this application. For ease of explanation, only the parts relevant to this embodiment are shown, and the details are as follows:

[0032] In one embodiment, please refer to Figures 2-7 A clamping device for grinding blades on an external cylindrical grinding machine includes a first clamping member 1 and a second clamping member 2. The first clamping member 1 is provided with a fixing rod 101, a first fixing plate 102 at one end of the fixing rod 101, a positioning table 104 at the end of the first fixing plate 102 away from the fixing rod 101, and a first fastening rod 103 at the end of the positioning table 104 away from the fixing rod 101. The grinding blade 3 is sleeved on the positioning table 104. The second clamping member 2 is provided with a second fixing plate 201, a second fastening rod 202 at one end of the second fixing plate 201, and a through hole 203 on the second fixing plate 201. The through hole 203 passes through the second fixing plate 201 and the second fastening rod 202. The through hole 203 is threadedly connected to the first fastening rod 103 so that the first fixing plate 102 and the second fixing plate 201 are brought close to each other to clamp the grinding blade 3.

[0033] By setting a first fastening rod 103 at one end of the first fixed plate 102 and a through hole 203 on the second fixed plate 201, with the through hole 203 threadedly connected to the first fastening rod 103, the first fixed plate 102 and the second fixed plate 201 are brought close together to clamp the grinding blade 3. This results in good clamping effect and stability, allowing for quick clamping and disassembly. By setting a positioning table 104 on the first fixed plate 102, the grinding blade 3 is fitted onto the positioning table 104. During use, the clamping device and the grinding blade 3 are fixed to the grinding machine spindle by the fixing rod 101, ensuring that the grinding blade 3 is concentric with the grinding machine spindle, thus improving the grinding effect and extending the service life and performance of the grinding blade 3.

[0034] For details, please refer to Figures 3-4 The positioning table 104 is circular, and its outer diameter matches the inner diameter of the grinding blade 3. The positioning table 104 on the first fastener 1 can be set to different sizes to serve a positioning function. In use, a positioning table 104 of appropriate size is selected according to the inner diameter of the grinding blade 3 so that the grinding blade 3 fits precisely on the positioning table 104, ensuring that the grinding blade 3 and the fixing rod 101 are coaxially arranged to improve the grinding effect.

[0035] Please see Figures 3-4 and Figures 6-7 The first fastening rod 103 has an external thread 106 on its outer wall and an internal thread 204 on its inner wall. The through hole 203 and the first fastening rod 103 are threaded together by the external thread 106 and the internal thread 204. The threaded connection ensures the connection between the first clamping member 1 and the second clamping member 2, improves the clamping effect of the first fixed plate 102 and the second fixed plate 201 on the grinding blade 3, and provides good clamping stability. In addition, the threaded connection also allows for quick fastening and quick disassembly.

[0036] Please see Figures 2-7 The fixing rod 101, the first fixing plate 102, the positioning table 104, and the first fastening rod 103 are all coaxially arranged. The second fixing plate 201, the second fastening rod 202, and the through hole 203 are also coaxially arranged. This arrangement ensures that when the clamping device and the grinding blade 3 are fixed to the grinding machine spindle by the fixing rod 101, the grinding blade 3 is coaxial with the grinding machine spindle, thus guaranteeing the grinding effect of the grinding blade 3.

[0037] Please see Figures 2-4 and Figure 8The fixing rod 101 has a fixing groove 105 at the end away from the first fixing plate 102. The fixing groove 105 is coaxially arranged with the fixing rod 101, and the inner wall of the fixing groove 105 is provided with a thread 107. The fixing rod 101 is used to connect with the grinding machine spindle. The tailstock 5 is equipped with the grinding machine spindle. In use, the fixing rod 101 is inserted into the tailstock 5, and the fixing rod 101 is threaded onto the grinding machine spindle through the fixing groove 105, thereby realizing the connection between the clamping device and the grinding machine spindle, that is, realizing the connection between the grinding blade 3 and the grinding machine spindle.

[0038] In one embodiment, please refer to Figures 2-4 The fixing rod 101 is configured as a tapered handle with a smaller diameter at one end and a larger diameter at the other end. The first fixing plate 102 is located at the larger diameter end of the fixing rod 101, and the fixing groove 105 is located at the smaller diameter end of the fixing rod 101. By configuring the fixing rod 101 as a tapered handle, high-precision centering is achieved through the tapered surface fit, thereby enabling quick installation and disassembly.

[0039] In one embodiment, please refer to Figures 5-7 The second fastening rod 202 is hexagonal. This design makes it convenient for the operator to use a wrench to tighten and loosen the second clamping part 2.

[0040] In one embodiment, please refer to Figure 3 and Figure 6 The first fixing plate 102 has a chamfer at one end near the fixing rod 101. The second fixing plate 201 has a chamfer at one end near the second fastening rod 202. The chamfers on the first fixing plate 102 and the second fixing plate 201 prevent operator injury during clamping and improve the aesthetics of the clamping device.

[0041] In one embodiment, please refer to Figure 2 and Figure 5 Both the first clamping member 1 and the second clamping member 2 are made of steel. In this embodiment, both the first clamping member 1 and the second clamping member 2 are made of 45# steel, which has high strength and good toughness. The first clamping member 1 and the second clamping member 2 can also be made of other types of steel.

[0043] In use, select a suitable positioning table 104 according to the inner diameter of the grinding blade 3, and fix the grinding blade 3 onto the positioning table 104; then rotate the second clamping member 2, and screw the second clamping member 2 onto the first fastening rod 103 through the external thread 106 and the internal thread 204. Continue to rotate the second clamping member 2 until the first fixing plate 102 and the second fixing plate 201 are both tightly fitted with the grinding blade 3, at which point the grinding blade 3 is clamped; then connect the fixing rod 101 to the grinding machine spindle in the tailstock 5 through the fixing groove 105, thus realizing the quick clamping of the grinding blade 3;

[0044] During grinding, rotate the tailstock 5 and the grinding wheel 4 to adjust the grinding blade 3 to a suitable angle, and start the grinding wheel 4 to grind the grinding blade 3.

[0045] In summary, this utility model provides a clamping device for grinding inserts on a cylindrical grinding machine. Compared with the prior art, by setting a first fastening rod at one end of a first fixed plate and a through hole on a second fixed plate, with the through hole threaded to the first fastening rod, the first and second fixed plates are brought close together to clamp the grinding insert, resulting in good clamping effect and stability, and enabling rapid clamping and disassembly. By setting a positioning table on the first fixed plate, the grinding insert is fitted onto the positioning table. During use, the clamping device and the grinding insert are fixed to the grinding machine spindle by the fixing rod, ensuring concentricity between the grinding insert and the grinding machine spindle, improving the grinding effect, and extending the service life and performance of the grinding insert.
