Description

Technical Field

[0001] This utility model relates to the technical field of grinding and repair devices, specifically to a device for rapidly grinding and repairing the height of pyrophyllite composite blocks. Background Technology

[0002] After being formed on a four-column hydraulic press, pyrophyllite blocks need to be calcined to meet performance requirements. The dimensional differences in the four directions of the calcined pyrophyllite blocks usually meet design requirements, but the height often fails to meet specifications, with some blocks significantly exceeding the specified height range.

[0003] In the existing technology, there is a lack of specialized equipment for the repair of pyrophyllite blocks with excessive height. The repair is mostly done manually with hand-held grinding tools, which has the following drawbacks: First, the processing efficiency is low and continuous batch processing cannot be achieved; second, the grinding accuracy is difficult to control and the height dimension is inconsistent; third, the manual operation is labor-intensive and the dust pollution generated during the grinding process is serious, which endangers the health of the operators.

[0004] To address the aforementioned issues, this invention aims to develop a device for rapidly grinding and repairing the height of pyrophyllite blocks, achieving efficient and precise repair of the height of pyrophyllite blocks, while also possessing an environmentally friendly dust removal function. Utility Model Content

[0005] The purpose of this invention is to provide a device for rapidly grinding and repairing the height of pyrophyllite synthetic blocks, so as to solve the problems of difficult control of grinding accuracy and poor height dimension consistency of existing grinding devices.

[0006] A device for rapidly grinding and restoring the height of pyrophyllite synthetic blocks includes a base, on which a bench drill is mounted, and a grinding head is fitted at the output end of the bench drill. The top of the base is provided with an adjustment mechanism for adapting to pyrophyllite blocks of different sizes.

[0007] Preferably, the adjustment mechanism includes a worktable located on the top of the base, two parallel slide rails on the worktable, multiple positioning holes on the worktable, the slide rails being fixed to one of the positioning holes by fixing bolts, and a locking mechanism on the base capable of fixing the position of the worktable.

[0008] Preferably, the locking mechanism includes a movable groove formed on the base, a lead screw rotatably disposed in the movable groove, one end of the lead screw passing through the movable groove and fixedly disposed with a rotating handle, a guide rod disposed parallel to the lead screw and fixedly disposed in the movable groove, and a clamping block threadedly connected to the body of the lead screw, the clamping block slidingly engaging with the guide rod.

[0009] Preferably, the sidewall of the clamping block that contacts the worktable is provided with a wear-resistant layer.

[0010] Preferably, the bench drill is equipped with a height adjustment rod, which is used to adjust the height position of the grinding head.

[0011] Preferably, the height adjustment rod is provided with scale markings.

[0012] Preferably, the contact area between the grinding head and the pyrophyllite block is provided with a dust removal port, and the dust removal port is connected to the dust collection device through an exhaust pipe.

[0013] The advantages of this utility model are as follows: The device for rapid grinding and repair of pyrophyllite composite blocks, through the setting of an adjustment mechanism, can adapt to pyrophyllite blocks of different sizes, eliminating the need for frequent clamp changes and meeting the repair needs of workpieces of various specifications. Its adaptability is superior to traditional dedicated grinding equipment, enhancing its versatility. The threaded transmission between the lead screw and the clamping block provides a large clamping force, and the anti-rotation limit of the guide rod reduces the vibration amplitude after the worktable is fixed, avoiding grinding accuracy deviations.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 3As shown, a device for rapidly grinding and repairing the height of pyrophyllite synthetic blocks includes a base 100, on which a bench drill 101 is mounted. The output end of the bench drill 101 is equipped with a grinding head 102. The top of the base 100 is provided with an adjustment mechanism 300 for adapting to pyrophyllite blocks of different sizes.

[0020] In this embodiment, the adjustment mechanism 300 includes a worktable 301 disposed on the top of the base 100. The worktable 301 is provided with two parallel slide rails 302. The worktable 301 is provided with a plurality of positioning holes 304. The slide rails 302 are fixed to one of the positioning holes 304 by fixing bolts 303. The base 100 is provided with a locking mechanism 200 that can fix the position of the worktable 301.

[0021] Based on the lateral dimensions of the pyrophyllite block to be repaired, loosen the fixing bolts 303 at the bottom of the slide rail 302, and move the two parallel slide rails 302 along the surface of the worktable 301 to match the width of the pyrophyllite block. Align the slide rails 302 with the corresponding positioning holes 304 on the worktable 301, and tighten the fixing bolts 303 to lock the slide rail position, ensuring no lateral deviation when the pyrophyllite block is pushed. By selecting different positioning holes to adjust the slide rail spacing, it can adapt to pyrophyllite blocks of different widths without the need to replace special fixtures, thus improving the versatility of the device. The spacing error of the positioning holes 304 is ≤0.1mm, ensuring the parallelism of the slide rails. The lateral deviation when the pyrophyllite block is pushed is ≤0.05mm, ensuring the uniformity of grinding.

[0022] In this embodiment, the locking mechanism 200 includes a movable groove 204 formed on the base 100. A lead screw 202 is rotatably disposed in the movable groove 204. One end of the lead screw 202 passes through the movable groove 204 and is fixedly provided with a rotating handle 203. A guide rod 205 is fixedly disposed in the movable groove 204 and is arranged parallel to the lead screw 202. A clamping block 201 is threadedly connected to the rod body of the lead screw 202. The clamping block 201 and the guide rod 205 are slidably engaged.

[0023] The worktable 301 is moved along the surface of the base 100, aligning its center with the center of the grinding head 102. The rotating handle 203 drives the lead screw 202 to rotate within the moving groove 204. Because the clamping block 201 is threadedly connected to the lead screw 202 and limited by the guide rod 205, the clamping block 201 moves along the guide rod 205 towards the worktable 301 until it is in close contact with the side wall of the worktable 301, thus achieving a stable fixation of the worktable 301 and preventing it from shaking during grinding. The threaded transmission between the lead screw 202 and the clamping block 201 provides a large clamping force. Combined with the anti-rotation limit of the guide rod 205, this reduces the vibration amplitude of the worktable 301 after fixation, preventing grinding accuracy deviations. The rotating handle 203 is designed to be labor-saving, allowing a single person to fix the worktable 301, which is more convenient and efficient than traditional bolt fixing.

[0024] In this embodiment, the sidewall of the clamping block 201 that contacts the worktable 301 is provided with a wear-resistant layer 206.

[0025] The wear-resistant layer 206 is made of polyurethane, which can reduce the frictional wear between the worktable 301 and the clamping block 201, thus extending the service life of the device.

[0026] In this embodiment, a height adjustment rod 103 is connected to the bench drill 101. The height adjustment rod 103 is used to adjust the height position of the grinding head 102. The height adjustment rod 103 is provided with scale markings.

[0027] Referring to the height deviation of the pyrophyllite block, observe the scale markings on the height adjustment rod 103. Rotate the height adjustment rod 103 to move the bench drill 101 and the grinding head 102 up and down, adjusting the bottom of the grinding head 102 to the "design height" position. Leave a small margin to ensure grinding accuracy. The scale markings clearly show the height of the grinding head 102. The adjustment error is ≤0.03mm. Compared with manual adjustment based on experience, this method improves the consistency of height dimensions, provides controllable accuracy, and is simple to operate. No additional measuring tools are required, and beginners can quickly master the adjustment method, reducing the operational threshold.

[0028] In this embodiment, a dust removal port 104 is provided in the contact area between the grinding head 102 and the pyrophyllite block, and the dust removal port 104 is connected to the dust collection device through the air duct 105.

[0029] During the grinding process, the dust collection device is turned on simultaneously. The dust collection port 104 generates negative pressure through the air duct 105, which directly sucks the pyrophyllite dust generated during grinding into the dust collection device. The dust collection port 104 is close to the grinding area to improve the dust collection rate, avoid direct dust emission, be environmentally friendly and pollution-free, reduce the harm to the respiratory tract of operators, and reduce the risk of occupational diseases.

[0030] Working Process and Principle: During use, the worktable 301 is moved along the surface of the base 100 until its center is aligned directly below the grinding head 102. Rotating the handle 203 causes the lead screw 202 to rotate within the moving groove 204. Because the clamping block 201 is threadedly connected to the lead screw 202 and limited by the guide rod 205, the clamping block 201 moves along the guide rod 205 towards the worktable 301 until it is in close contact with the side wall of the worktable 301, thus achieving stable fixation of the worktable 301 and preventing it from shaking during grinding. Based on the lateral dimensions of the pyrophyllite block to be repaired, the fixing bolts 303 at the bottom of the slide rails 302 are loosened, and the two parallel slide rails 302 are moved along the surface of the worktable 301 until the distance between the two slide rails matches the width of the pyrophyllite block. Align the slide rail 302 with the corresponding positioning holes 304 on the worktable 301, tighten the fixing bolts 303 to lock the slide rail position, and ensure that there is no lateral deviation when pushing the pyrophyllite block. Start the bench drill 101, and the grinding head 102 starts to rotate at high speed. The operator holds the pyrophyllite block to be repaired, places one end against the inside of the slide rail 302, and pushes it at a uniform speed along the slide rail to below the grinding head 102. The top of the pyrophyllite block that exceeds the tolerance contacts the grinding head. The excess material is removed by the cutting action of the grinding head. Continue to push the pyrophyllite block until it completely passes through the grinding area to complete a single grinding. Repeated operation can realize continuous batch repair of multiple pyrophyllite blocks. During the grinding process, the dust collection device is turned on at the same time. The dust collection port 104 generates negative pressure through the exhaust pipe 105 to directly suck the pyrophyllite dust generated during grinding into the dust collection device.

[0031] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
