Description

Technical Field

[0001] This utility model belongs to the technical field of tools for disassembling grinding machine chucks, and relates to an auxiliary tool for disassembling grinding machine chucks. Background Technology

[0002] The left and right chucks of a peripheral grinder are used for clamping and positioning the workpiece. The right chuck serves as a follow-up support mechanism. Therefore, during installation, a clearance fit is required between the right chuck and the bushing. However, during the grinding process, grinding dust is generated and mixed with the high-pressure coolant, entering the space between the chuck and the bushing. As the working time increases, the grinding dust forms lumpy deposits, causing the right chuck and the bushing to stick together. This increases the difficulty of disassembling the right chuck. In daily operation, the end of the right chuck is often clamped with pliers, and then a hammer is used to strike it along the axial direction to disengage the right chuck from the bushing. However, during the striking process, radial shearing force is inevitably generated, which may cause the right chuck to break. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an auxiliary disassembly tool that avoids the use of a hammer and reduces the risk of chuck breakage.

[0004] The objective of this utility model can be achieved through the following technical solution: an auxiliary disassembly tool for a grinding machine chuck, comprising: Separate blocks; The nut is threaded onto the outside of the separator block, and the bottom end of the nut abuts against the grinding machine; The top block is detachably connected to one end of the separating block. The top block is used to abut one end of the chuck or is connected to the chuck by bolts. When the separating block moves away from the grinding machine relative to the nut, the top block moves out of the grinding machine with the chuck.

[0005] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the separating block includes a separating ring and an operating ring, one end of the separating ring is connected to one end of the operating ring, and the separating ring and the operating ring are coaxially arranged.

[0006] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the outer surface of the separating ring is provided with an external thread, the inner wall of the nut is provided with an internal thread for connecting the external thread, the outer side of the operating ring is surrounded by multiple operating surfaces, the inner diameter of the separating ring is larger than the inner diameter of the operating ring, and the bottom end of the inner wall of the separating ring is provided with a first chamfer.

[0007] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the top block includes a bottom ring plate and a top ring disposed on the bottom ring plate. Both the top ring plate and the bottom ring plate have openings for the chuck to pass through, and both the bottom ring plate and the top ring have receiving channels inside.

[0008] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the operating ring has at least two lower insertion holes on the end face away from the separation ring, and the bottom ring plate has upper insertion holes corresponding to the lower insertion holes. The upper insertion holes and the lower insertion holes are connected by pins.

[0009] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the top surface of the operating ring is provided with a ring bar, and the bottom surface of the bottom ring plate is provided with a ring groove, and the ring bar is movably engaged into the ring groove.

[0010] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the diameter of the receiving channel is greater than or equal to the diameter of the middle part of the chuck, the bottom end of the receiving channel of the bottom ring plate is provided with a downward slope, and the top end of the receiving channel of the top ring is provided with a second chamfer.

[0011] In the aforementioned auxiliary disassembly tool for a grinding machine chuck, the diameter of the receiving channel is smaller than the diameter of the end of the chuck furthest from the grinding machine.

[0012] In the above-mentioned auxiliary disassembly tool for a grinding machine chuck, the diameter of the receiving channel is greater than or equal to the diameter of the end of the chuck away from the grinding machine, and the side of the top ring is provided with at least one limiting hole, and each limiting hole is fitted with a bolt for clamping the chuck.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the auxiliary disassembly tool of this utility model is used to disassemble the chuck, the separating block is driven to rotate relative to the nut. Since the nut is against the step surface of the grinding machine and is stationary relative to the step surface, the separating block moves away from the grinding machine relative to the nut. In this way, the top block will move the chuck out of the grinding machine with it, thus avoiding the need for people to remove the chuck by knocking, thereby avoiding the chuck from breaking and better protecting the chuck.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1 like Figure 1 — Figure 3 As shown, the auxiliary disassembly tool for a grinding machine chuck of this utility model includes a separating block 100, a nut 200, a top block 300, and a bolt 310.

[0022] In this invention, the chuck 400 includes a rod portion 410 located in the middle, an end portion 420 at one end of the rod portion 410, and an insertion portion 440 for insertion into the grinding machine 500 at the other end of the rod portion 410. A frustum portion 430 is provided between the rod portion 410 and the insertion portion 440. The grinding machine 500 includes a mounting head 510, an inner clamping ring 520 at the end portion 420 of the mounting head 510, and a stepped surface 530 between the side of the mounting head 510 and the side of the inner clamping ring 520.

[0023] Nut 200 is threaded onto the outside of separator block 100, and the bottom end of nut 200 abuts against grinding machine 500; top block 300 is detachably connected to one end of separator block 100. Top block 300 abuts against one end of chuck 400 or is connected to chuck 400 via bolt 310. When removing chuck 400 from grinding machine 500, the operation steps are as follows: First, thread nut 200 is installed onto separator ring 110 of separator block 100, and the bottom surface of nut 200 is flush with the end face of separator ring 110 away from operating ring 120. Then, separator block 100 is placed on grinding machine 500, and the bottom surface of nut 200 abuts against the stepped surface 530 of grinding machine 500. Afterwards, top block 300 is fitted onto... On the chuck 400, one end of the top block 300 is aligned with the end 420 of the chuck 400, or the top ring 330 is connected to the chuck 400 by bolts 310. Then, the top block 300 is connected to the separating block 100. After that, the separating block 100 is driven to rotate relative to the nut 200. Since the nut 200 abuts against the step surface 530 and the nut 200 is stationary relative to the step surface 530, the separating block 100 moves away from the grinding machine 500 relative to the nut 200. In this way, the top block 300 will move the chuck 400 out of the grinding machine 500 with it, thereby avoiding the chuck 400 from being moved out by knocking, thus avoiding the chuck 400 from breaking and better protecting the chuck 400.

[0024] The separating block 100 includes a separating ring 110 and an operating ring 120. One end of the separating ring 110 is connected to one end of the operating ring 120. The separating ring 110 and the operating ring 120 are coaxially arranged. The outer surface of the separating ring 110 is provided with an external thread 111. The inner wall of the nut 200 is provided with an internal thread 210 for connecting the external thread 111. The outer surface of the operating ring 120 is surrounded by multiple operating surfaces 121. When it is necessary to move the separating block 100 and the nut 200 relative to each other, a first pair of pliers (not shown in the figure) suitable for the nut 200 is used to clamp the nut 200. Next, the second clamp (not shown in the figure) applied to the operating ring 120 clamps the corresponding operating surface 121. Then, the first clamp is kept stationary while the second clamp is rotated so that the operating ring 120 and the separating ring 110 rotate simultaneously relative to the nut 200. At this time, the nut 200 abuts against the step surface 530 and remains stationary relative to the step surface 530. The nut 200 and the separating ring 110 are connected by threads. In this way, the distance between the separating ring 110 and the nut 200 can be controlled so that the top block 300 installed on the operating ring 120 can move out of the grinding machine 500 with the chuck 400.

[0025] The inner diameter of the separating ring 110 is greater than the inner diameter of the operating ring 120. The inner diameter of the separating ring 110 is greater than or equal to the outer diameter of the inner clamping ring 520. The inner diameter of the operating ring 120 is greater than or equal to the inner diameter of the inner clamping ring 520. The inner diameter of the operating ring 120 is greater than or equal to the diameter of the insertion part 440. The diameter of the insertion part 440 is greater than the width of other parts of the chuck 400. Thus, when the separating block 100 is placed on the chuck 400 and moved from the end 420 of the chuck 400 toward the insertion part 440, neither the inner clamping ring 520 nor the insertion part 440 will interfere with the separating block 100, thereby successfully placing the separating block 100 on the stepped surface 530 of the grinding machine 500.

[0026] A first chamfer 112 is provided at the bottom end of the inner wall of the separation ring 110.

[0027] The top block 300 includes a bottom ring plate 320 and a top ring 330 disposed on the bottom ring plate 320. Both the top ring 330 and the bottom ring plate 320 have openings 340 for the chuck 400 to pass through. The width of the opening 340 is greater than the outer diameter of the rod 410, allowing the rod to pass smoothly through. Both the bottom ring plate 320 and the top ring 330 have receiving channels 350 inside. The operating ring 120 has at least two lower insertion holes 122 on its end face away from the separating ring 110. The bottom ring plate 320 has upper insertion holes 321 corresponding to the lower insertion holes 122. The upper insertion holes 321 and lower insertion holes 122 are connected by pins 3211. After the separating block 100 is installed, the top block 300 needs to be fitted onto the rod 410 of the chuck 400. Specifically… The bottom ring plate 320 and the top ring 330 are simultaneously fitted onto the rod portion 410 through the opening 340. Then, the top block 300 is rotated around the rod portion 410 until each upper insertion hole 321 is aligned with the corresponding lower insertion hole 122. The pin 3211 is then inserted into the upper insertion hole 321 and the lower insertion hole 122 to achieve the connection between the top block 300 and the separating block 100. Therefore, when the separating block 100 is rotated relative to the nut 200, the top block 300 will also rotate synchronously with the separating block 100 and move relative to the nut 200. Thus, when the separating block 100 moves outward relative to the grinding machine 500, the top block 300 will also move outward synchronously, thereby driving the chuck 400 to move outward from the grinding machine 500, achieving the purpose of separating the insertion part 440 of the chuck 400 from the inner clamping ring 520 of the grinding machine 500.

[0028] The diameter of the receiving channel 350 is greater than or equal to the diameter of the rod 410. With this structure, the top block 300 can move smoothly relative to the rod 410.

[0029] The bottom end of the receiving channel 350 of the bottom ring plate 320 is provided with a downward slope 322. When the top block 300 is fitted onto the rod 410, the bottom ring plate 320 faces the frustum 430, and the downward slope 322 is located at the end of the bottom ring plate 320 facing the frustum 430. In this way, the downward slope 322 will avoid the side of the frustum 430, so that the top block 300 can be smoothly fitted onto the rod 410.

[0030] The top of the receiving channel 350 of the top ring 330 is provided with a second chamfer 331.

[0031] The diameter of the receiving channel 350 is smaller than the diameter of the end of the chuck 400 away from the grinding machine 500, that is, the diameter of the receiving channel 350 is smaller than the diameter of the end 420 of the chuck 400. An inclined surface (not shown in the figure) is provided on the side of the end 420. When the top block 300 moves outward relative to the grinding machine 500, the second chamfer 331 will contact the inclined surface to support the inclined surface of the end 420, so that the top ring 330 can support the end 420 and move the chuck 400 outward relative to the grinding machine 500 until the insertion part 440 of the chuck 400 is removed from the inner clamping ring 520 of the grinding machine 500. This allows the auxiliary disassembly tool to be used with the chuck 400 having the end 420.

[0032] Example 2 like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the chuck 400 and the top ring 330 have been changed in this embodiment.

[0033] Specifically, in this embodiment, the chuck 400 does not have the end 420 as in Embodiment 1. The diameter of the receiving channel 350 is greater than or equal to the diameter of the end of the chuck 400 away from the grinding machine 500. The side of the top ring 330 is provided with at least one limiting hole 332. Each limiting hole 332 is equipped with a bolt 310. The bolt 310 is used to clamp the chuck 400. When connecting the top ring 330 and the chuck 400 together, the bolt 310 is required. Specifically, when two bolts 310 are used, the two bolts 310 need to be threaded through the corresponding limiting hole 332. Since the two limiting holes 332 are coaxially arranged, and the straight line where the limiting holes 332 are located just passes through the central axis of the receiving channel 350, the two bolts 310 will clamp the rod 410, so that the top ring 330 can move with the chuck 400. Thus, the auxiliary disassembly tool can be used for chucks 400 that do not have an end 420.

[0034] Example 3 like Figure 5 As shown, the difference between this embodiment and embodiments one and two is that the connection relationship between the bottom ring plate and the operating ring is changed in this embodiment.

[0035] Specifically, the top surface of the operating ring 120 is provided with a ring bar 123, and the bottom surface of the bottom ring plate 320 is provided with a ring groove 323. The ring bar is movably inserted into the ring groove. The operating ring of the ring bar is coaxially arranged, and the ring groove is coaxially arranged with the bottom ring plate. When the separating block rotates relative to the nut, the ring bar can rotate in the ring groove, thereby allowing the separating block to rotate relative to the top block around the central axis of the separating block. In this way, when the top of the top ring presses the end or the two bolts clamp the rod, the rotating separating block will not drive the top block and the chuck to rotate synchronously, so as to avoid friction between the insertion part of the chuck and the inner wall of the inner clamping ring, thereby reducing the risk of wear on the outer surface of the insertion part due to friction. In addition to the above structural arrangement, the top surface of the operating ring 120 can also be provided with a ring groove 323, and the bottom surface of the bottom ring plate 320 can be provided with a ring bar 123.

[0036] Example 4 like Figure 1 — Figure 5 As shown, this embodiment illustrates a method for using the aforementioned auxiliary disassembly tool, including: Step 1: Thread the nut 200 onto the separating ring 110 of the separating block 100, and make the bottom surface of the nut 200 flush with the end face of the separating ring 110 away from the operating ring 120. Step 2: Place the separating block 100 onto the chuck 400 and move it from the end of the chuck 400 away from the insertion part 440 toward the insertion part 440 until the bottom surface of the nut 200 abuts against the grinding machine 500. Step 3: Place the top block 300 onto the rod portion 410 of the chuck 400 through the opening 340, and align the top ring 330 of the top block 300 with the end 420 of the chuck 400, or connect the top ring 330 to the chuck 400 with at least one bolt 310. Step 4: Rotate the top block 300 around the rod part 410 until each upper insertion hole 321 is aligned with the corresponding lower insertion hole 122, and insert the pin 3211 into the upper insertion hole 321 and the lower insertion hole 122 or move the ring bar into the ring groove to achieve the connection between the top block 300 and the separation block 100. Step 5: Clamp the nut 200 with the first clamp, and then clamp the corresponding operating surface 121 with the second clamp, which is suitable for the operating ring 120. After that, keep the first clamp still and operate the second clamp to rotate so that the operating ring 120 and the separating ring 110 rotate simultaneously relative to the nut 200. At this time, the nut 200 abuts against the step surface 530 and remains stationary relative to the step surface 530. The nut 200 and the separating ring 110 are connected by threads, which increases the distance between the separating ring 110 and the nut 200. Since the top block 300 and the separating block 100 are connected by the pin 3211, the top block 300 will also rotate synchronously with the separating block 100. At the same time, the distance between the top block 300 and the nut 200 will also increase, so that the top block 300 can move out of the grinding machine 500 with the chuck 400.

[0037] By using the above-mentioned auxiliary disassembly tools, the chuck 400 can be easily removed from the grinder 500, avoiding the need to use a hammer and reducing the risk of the chuck 400 being broken.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "first," "second," or "a" in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
