DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] Embodiment 1: Figures 1 to 8 As shown, a mold accessory grinding device described in an embodiment of the present invention includes a bearing portion, a grinding mechanism, a control mechanism and a clamping mechanism.

[0046] The bearing part includes a bearing platform 1, a supporting box 4 and an installation box 5, both of which are arranged on the upper end surface of the bearing platform 1, wherein the supporting box 4 is fixedly installed on the upper end surface of the bearing platform 1, and the installation box 5 is slidably installed on the upper end surface of the bearing platform 1.

[0047] The grinding mechanism includes a fixed frame 15, a movable frame 17 and a grinding strip 16. One end of the grinding strip 16 is rotatably connected to the fixed frame 15. The grinding strip 16 is semi-cylindrical and is used to grind the conical inner wall of the workpiece. During grinding, the outer wall of the grinding strip 16 is in linear contact with the inner wall of the workpiece.

[0048] The outer wall of the grinding strip 16 is provided with a waist-shaped groove, and the upper end of the movable frame 17 slides with the waist-shaped groove through a pin shaft. The sliding movable frame 17 drives the grinding strip 16 to rotate, thereby changing the inclination angle of the grinding strip 16. In actual operation, the inner wall of the workpiece with different inclination angles can be ground.

[0049] The control mechanism includes a mounting cylinder 13 arranged on one side of the supporting box 4 , a pressing cylinder 3 for pressing the movable frame 17 , and a control cylinder 8 for controlling the pressing cylinder 3 .

[0050] The movable frame 17 is slidably installed on the outer wall of the mounting tube 13, and the fixed frame 15 is fixedly installed on the outer wall of the mounting tube 13. The mounting tube 13 provides support for the movable frame 17 and the fixed frame 15. When grinding the workpiece, the grinding strip 16 is inserted into the interior of the workpiece, and then the sliding pressure tube 3 pushes the movable frame 17 to slide until the grinding strip 16 fits with the inner wall of the workpiece. At this time, the workpiece is rotated and the inner wall of the workpiece is grinded by the grinding strip 16. Compared with Chinese patent CN217619483U, a mold accessory grinding device is used to grind the conical inner wall of the workpiece by an arc plate. When in use, it can adapt to the use of conical inner wall workpieces with different inclination angles, and keep in contact with the inner wall of the workpiece during grinding, thereby improving the adaptability range and the work quality.

[0051] The clamping mechanism includes a clamping cylinder 9 and an adjusting component. The clamping cylinder 9 is rotatably mounted on the inner wall of the mounting box 5 and is used to fix the workpiece. The outer wall of the clamping cylinder 9 is provided with bolts. After the workpiece is inserted into the inner cavity of the clamping cylinder 9, the bolts are rotated to clamp and fix the workpiece.

[0052] The rotation of the clamping cylinder 9 is controlled by the regulating assembly. After the workpiece and the clamping cylinder 9 are fixed, the workpiece is driven to rotate by rotating the clamping cylinder 9 to achieve grinding of the inner wall of the workpiece.

[0053] One end of the control cylinder 8 is fixedly connected to the inner wall of the support box 4 , and the other end is fixedly connected to the axial end of the top pressure cylinder 3 , wherein the control cylinder 8 is a common hydraulic cylinder for controlling the sliding of the top pressure cylinder 3 .

[0054] A support plate 12 is fixedly mounted on the outer wall of the support box 4 , and an axial end of the mounting tube 13 is fixedly connected to the outer wall of the support plate 12 . The support box 4 provides support for the mounting tube 13 .

[0055] In order to improve the sliding stability of the pressing cylinder 3 , the axis of the pressing cylinder 3 coincides with the axis of the mounting cylinder 13 , thereby improving the sliding stability of the pressing cylinder 3 .

[0056] A transfer cylinder 20 for connecting to a water source is fixedly mounted on one axial end of the mounting cylinder 13. The mounting cylinder 13 is a hollow structure. A diverter cylinder 14 is fixedly mounted on one end of the mounting cylinder 13 away from the transfer cylinder 20. The diverter cylinder 14 is used to connect to an external coolant storage chamber.

[0057] During grinding, the axis of the workpiece coincides with the axis of the mounting tube 13. At this time, coolant is introduced into the inner cavity of the mounting tube 13 through the adapter tube 20. The coolant is sprayed out from the other end of the mounting tube 13, impacting the apex of the conical inner wall of the workpiece, and then diffused along the radial outer wall, thereby evenly spraying on the inner wall of the workpiece. During grinding, the coolant is evenly sprayed to further improve the efficiency of the grinding process.

[0058] In order to facilitate uniform diffusion of the coolant, the axis of the diverter tube 14 coincides with the axis of the mounting tube 13, and the diverter tube 14 is truncated. The coolant sprayed from the mounting tube 13 impacts the radial outer wall of the mounting tube 13, thereby diffusing to the surroundings.

[0059] In order to facilitate the coolant to impact the apex of the cone inner wall of the workpiece, a through hole is provided in the middle of the diverter tube 14, so that when the coolant is sprayed out, the coolant can impact the apex of the cone inner wall of the workpiece through the through hole.

[0060] A reflow hood 7 is fixedly installed on the outer wall of the top pressure cylinder 3. The inner wall of the reflow hood 7 is set to be an arc shape. When the coolant flows along the inner wall of the workpiece, it will be discharged from the open end of the workpiece due to inertia and impact the inner wall of the reflow hood 7. The extended surface of the inner wall of the reflow hood 7 intersects with the outer wall of the workpiece, so that the coolant impacting the reflow hood 7 can move toward the outer wall of the workpiece, thereby flushing the outer wall of the workpiece, further improving the cooling efficiency of the workpiece.

[0061] The regulating component includes a control motor 6, a control worm wheel 10 and a control worm 11. The control worm wheel 10 and the control worm 11 are both rotatably mounted in the inner cavity of the mounting box 5 and mesh with each other. Rotating the control worm 11 drives the control worm wheel 10 to rotate.

[0062] The control worm gear 10 is fixedly mounted on the outer wall of the clamping tube 9 , and the clamping tube 9 is driven to rotate by rotating the control worm gear 10 , thereby controlling the rotation of the workpiece.

[0063] The control motor 6 is fixedly mounted on the outer wall of the mounting box 5, and the output shaft of the control motor 6 is fixedly connected to the axial end of the control worm 11. The control motor 6 is used to drive the control worm 11 to rotate, thereby providing power for the rotation of the workpiece during grinding.

[0064] In order to slide and adjust the workpiece along the axis of the workpiece after the workpiece and the clamping tube 9 are fixed, a telescopic cylinder is provided on the outer wall of the supporting platform 1, and a guide block is fixedly installed on the bottom surface of the mounting box 5. The outer wall of the guide block slides and fits with the inner wall of the supporting platform 1. The movable end of the telescopic cylinder extends to the inner wall of the supporting platform 1 and is fixedly connected to the outer wall of the guide block. The telescopic cylinder is a common hydraulic cylinder, which is used to control the sliding of the guide block, thereby controlling the sliding of the mounting box 5. After the workpiece and the clamping tube 9 are fixed, the mounting box 5 is slidably adjusted to control the sliding of the workpiece along the axial direction.

[0065] The coolant sprayed when grinding the workpiece eventually falls on the upper end surface of the carrier 1 due to gravity. A through hole for the coolant to pass through is opened on the upper end surface of the carrier 1. A recovery box 18 for recovering the coolant is fixedly installed on the bottom surface of the carrier 1. The recovery box 18 is located at the through hole on the upper end surface of the carrier 1 and is used to recover and store the coolant.

[0066] A control pump 19 is provided on the outer wall of the recovery box 18, and the output end of the control pump 19 is connected to the outer wall of the adapter tube 20. The control pump 19 is a common circulation pump. A connecting tube 25 is fixedly installed at the bottom of the inner cavity of the recovery box 18. The bottom of the connecting tube 25 is connected to the input end of the control pump 19 through a conduit. The coolant recovered by the recovery box 18 converges into the inside of the connecting tube 25. At this time, the coolant in the recovery box 18 is extracted by the control pump 19 and then discharged through the adapter tube 20, thereby realizing the recycling of the coolant.

[0067] It should be noted in this embodiment that before processing, an appropriate amount of coolant needs to be injected into the inner cavity of the recovery box 18 to ensure that the control pump 19 can normally extract the coolant in the early stage of grinding.

[0068] The coolant after flushing the workpiece contains a large amount of grinding chips. In order to prevent the grinding chips from affecting the operation of the control pump 19, a filter plate 2 is fixedly installed on the upper end surface of the support platform 1. The filter plate 2 is located directly above the recovery box 18. When the coolant is recovered, the impurities inside the coolant are filtered through the filter plate 2, thereby preventing the impurities from entering the interior of the control pump 19.

[0069] A connecting plate 21 is fixedly installed at the bottom of the filter plate 2. The filter plate 2 is made of elastic material. The filter plate 2 is driven to vibrate by tapping the connecting plate 21. During filtering, debris can be prevented from clogging the through holes of the filter plate 2.

[0070] In order to facilitate tapping the connecting plate 21, a guide cylinder 22 is fixedly installed on the inner wall of the recovery box 18, and a tapping shaft 23 for tapping the outer wall of the connecting plate 21 is fixedly installed on the inner wall of the guide cylinder 22. A spring is fixedly installed on the inner wall of the guide cylinder 22, and the other end of the spring is fixedly connected to the outer wall of the tapping shaft 23. When it is necessary to tap the connecting plate 21, the tapping shaft 23 is pulled to drive the spring to deform, and then the tapping shaft 23 is released. The elastic potential energy released by the spring drives the tapping shaft 23 to tap the connecting plate 21, thereby achieving the cleaning of the holes in the filter plate 2.

[0071] The inner wall of the connecting tube 25 is rotatably mounted with turbine blades 26. When the control pump 19 is working, water flows in the inner cavity of the connecting tube 25, thereby flushing the turbine blades 26 and driving the turbine blades 26 to rotate.

[0072] A mounting plate 27 is fixedly mounted at the center position of the axial end of the turbine blade 26 via a coupling shaft, and the mounting plate 27 is driven to rotate when the turbine blade 26 rotates.

[0073] A transmission block 24 for pushing the tapping shaft 23 is fixedly mounted on the radial outer wall of the mounting disk 27. The outer wall of the transmission block 24 is inclined. When the mounting disk 27 rotates, the transmission block 24 is driven to rotate until the inclined surface of the transmission block 24 contacts the outer wall of the tapping shaft 23, thereby pushing the tapping shaft 23 to slide. After the transmission block 24 is separated from the tapping shaft 23, the tapping shaft 23 is driven by a spring to tap the outer wall of the connecting plate 21, thereby driving the filter plate 2 to vibrate.

[0074] Embodiment 2: Figures 9 and 10 As shown in Comparative Example 1, another embodiment of the present invention is:

[0075] The grinding chips generated when grinding the workpiece contain a large amount of metal substances, which can be utilized after being recovered. The filter plate 2 is set at an angle, and the grinding chips filtered on the filter plate 2 are gathered to the bottom of the inclined filter plate 2 through the vibration generated by knocking the connecting plate 21, so as to facilitate the recovery of the grinding chips.

[0076] A storage box 29 is fixedly mounted on the side wall of the support platform 1. The storage box 29 is used to store recovered grinding chips. A cover plate is provided on the outer wall of the storage box 29, and the cover plate is fixed to the storage box 29 by screws.

[0077] A barrier layer 30 is fixedly installed on the inner wall of the storage box 29. The barrier layer 30 is a common sponge. A recovery pipe 28 is fixedly installed on the upper end surface of the storage box 29. The other end of the recovery pipe 28 extends to the top of the filter plate 2, connecting one side of the barrier layer 30 to an external negative pressure chamber, thereby forming a negative pressure on the inner wall of the storage box 29. At this time, the grinding chips on the filter plate 2 are absorbed by the recovery pipe 28. After the grinding chips enter the inner cavity of the storage box 29, they are filtered and blocked by the barrier layer 30, thereby staying in the inner cavity of the storage box 29, thereby realizing the recovery of the grinding chips.

[0078] After the grinding chips are recovered into the inner cavity of the storage box 29, the grinding chips inside the storage box 29 are swept out by removing the cover plate, so as to facilitate centralized processing.

[0079] A storage cylinder 34 is fixedly mounted on the outer wall of the mounting box 5 , a control piston 33 is elastically mounted in the inner cavity of the storage cylinder 34 , and the outer wall of the control piston 33 is provided with rubber and fits with the inner wall of the storage cylinder 34 .

[0080] An air inlet pipe 32 and an air outlet hole are disposed on the outer wall of the storage cylinder 34 , and a one-way valve is disposed at both the air inlet pipe 32 and the air outlet hole.

[0081] During the reciprocating sliding of the control piston 33 , the air inlet pipe 32 is used to inject gas into the inner cavity of the storage cylinder 34 , and the exhaust hole is used to exhaust gas from the inner cavity of the storage cylinder 34 to the outside.

[0082] Among them, a spring is provided on the outer wall of the control piston 33, and the other end of the spring is fixedly connected to the inner wall of the storage tube 34. A transmission inclined plate 35 is fixedly installed on the axial end of the control piston 33, and a control inclined plate 31 for pressing the transmission inclined plate 35 is fixedly installed on the axial end of the control worm gear 10. The elastic force exerted on the control piston 33 drives the transmission inclined plate 35 to have a tendency to approach the control inclined plate 31 in real time.

[0083] The control slant plate 31 is driven to rotate during the rotation of the control worm gear 10. At this time, the control slant plate 31 is pressed against the transmission slant plate 35 to slide, and cooperates with the elastic force of the spring, so that the control piston 33 is driven to slide back and forth by the rotation of the control worm gear 10. The other end of the air intake pipe 32 is connected to the inner cavity of the storage box 29. When air is sucked into the inner cavity of the storage cylinder 34, negative pressure is generated inside the storage box 29 to absorb debris on the filter plate 2.

[0084] In this embodiment, the filter plate 2 is vibrated by knocking the connecting plate 21 with the knocking shaft 23, which can not only prevent the grinding chips from blocking the holes of the filter plate 2, but also, since the filter plate 2 is tilted, when the filter plate 2 vibrates, it is easy for the grinding chips to gather to the bottom, thereby improving the efficiency of absorbing the grinding chips, which promote each other.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
