Description

TECHNICAL FIELD

[0001] The utility model belongs to the tool storage technical field, and specifically, it relates to a PCD tool storage rack. BACKGROUND

[0002] In the field of mechanical processing, PCD tools play a key role in the finishing of non-ferrous metal surfaces, holes and the like due to their high hardness, wear resistance and excellent cutting performance, and are widely used in the automotive industry and the aerospace field. Proper storage of PCD tools is crucial during the machining process, which not only affects the service life of the tool itself but also affects the machining accuracy and efficiency.

[0003] The common storage method is to simply place the PCD tool in the internal placing groove, relying only on the rubber pad for buffering protection. However, during the moving process, vehicle bumps, handling vibrations and other unavoidable situations will cause the PCD tool to shake in the storage rack. For example, when the PCD tool needs to be transferred from one machining workshop to another or needs to be carried when going out for equipment maintenance, due to the lack of sufficient and effective fixing measures, the tool shaking amplitude gradually increases, and eventually falls out of the storage rack. Once the tool falls, it may cause damage to the tool edge and deformation of the tool body, seriously affecting the accuracy and service life of the tool. In some extreme cases, the falling tool may also cause injury to personnel or delay production progress due to damage.

[0004] Currently, there is no effective solution to the problems in the related art. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model protection.

[0031] In the description of the utility model, it is understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0032] Please refer to Figures 1-7The utility model discloses a PCD cutter storage rack, including the storage rack body 1, a plurality of placing cavities 2 are seted up in the storage rack body 1, the sliding installation of bearing mechanism 3 is located in the placing cavity 2 on the storage rack body 1, the rotation installation of hand drive mechanism 4 is located on bearing mechanism 3, the symmetrical meshing of travel mechanism 5 has on hand drive mechanism 4, two travel mechanism 5 rotation installation is located on bearing mechanism 3, the sliding installation of limiting plate 6 is located on bearing mechanism 3, limiting plate 6 with two travel mechanism 5 is screwed and is installed, the symmetrical installation of circular clamping block 7 is located on bearing mechanism 3, the clamping mechanism 8 of the circular clamping block 7 clamping is equipped in the storage rack body 1, the one end of bearing mechanism 3 and limiting plate 6 all is equipped with foamed cotton 9.

[0033] The utility model discloses a PCD cutter storage rack, including the storage rack body 1, a plurality of placing cavities 2 are seted up in the storage rack body 1, the sliding installation of bearing mechanism 3 is located in the placing cavity 2 on the storage rack body 1, the rotation installation of hand drive mechanism 4 is located on bearing mechanism 3, the symmetrical meshing of travel mechanism 5 has on hand drive mechanism 4, two travel mechanism 5 rotation installation is located on bearing mechanism 3, the sliding installation of limiting plate 6 is located on bearing mechanism 3, limiting plate 6 with two travel mechanism 5 is screwed and is installed, the symmetrical installation of circular clamping block 7 is located on bearing mechanism 3, the clamping mechanism 8 of the circular clamping block 7 clamping is equipped in the storage rack body 1, the one end of bearing mechanism 3 and limiting plate 6 all is equipped with foamed cotton 9.

[0034] The symmetrical circular clamping blocks 7 on the bearing mechanism 3 cooperate with the clamping mechanism 8 in the storage rack body 1. When the operator pushes the bearing mechanism 3 to slide towards the placement cavity 2, the two circular clamping blocks 7 gradually approach the corresponding clamping mechanism 8. As the bearing mechanism 3 continues to advance, the circular clamping blocks 7 begin to contact the clamping mechanism 8. Due to the special shape of the circular clamping blocks 7, during the further pushing process of the bearing mechanism 3, the internal components at both ends of the clamping mechanism 8 are forced to move away from each other along the contour of the circular clamping blocks 7. Until the protrusions at both ends of the circular clamping blocks 7 pass the position where the internal components of the clamping mechanism 8 are separated, at this time, the elastic elements inside the clamping mechanism 8 cause the internal components at both ends to move closer to each other along the outer wall of the circular clamping blocks 7. Finally, the clamping mechanism 8 tightly clamps the circular clamping blocks 7 by the elasticity of the components at both ends, thereby stably fixing the bearing mechanism 3 in the placement cavity 2, effectively preventing the risk of accidental sliding out of the bearing mechanism 3 during transportation.

[0035] It is important to note that the friction force of the elasticity of the components at both ends of the clamping mechanism 8 on the circular clamping blocks 7 will be much greater than the sliding force of the bearing mechanism 3 (but will not hinder the normal pulling out of the bearing mechanism 3). When the bearing mechanism 3 slides back into the placement cavity 2, even if it is disturbed by a larger external force, it can always tightly clamp the clamping blocks 7 under the elastic action of the components at both ends of the clamping mechanism 8. In the process of daily transportation of the storage rack, bumps and vibrations are inevitable, at this time, the bearing mechanism 3 will be subjected to a certain sliding force, but due to the elasticity of the components at both ends of the clamping mechanism 8 far exceeding the sliding force of the bearing mechanism 3, the restoring force generated by the elasticity of the components at both ends of the clamping mechanism 8 is sufficient to overcome the sliding tendency of the bearing mechanism 3, ensuring that the bearing mechanism 3 is stably fixed in the placement cavity 2, greatly reducing the risk of sliding out of the bearing mechanism 3 due to accidental external force, and providing more reliable protection for the safety of PCD cutters during movement.

[0036] In one embodiment, for the above-mentioned storage rack body 1, a handle 101 is rotatably installed on the top of the storage rack body 1, and support legs 102 are fixedly installed at the four corners of the bottom of the storage rack body 1.

[0037] The handle 101 rotatably installed on the top of the storage rack body 1 can be easily held and lifted upwards by the operator when moving the storage rack. Since the handle 101 is rotatably connected to the storage rack body 1, the angle can be flexibly adjusted. At the same time, the support legs 102 fixedly installed at the four corners of the bottom of the storage rack body 1 separate the storage rack body 1 from the placement surface when the storage rack body 1 is placed on the ground or other flat surfaces, avoiding direct contact of the bottom of the storage rack body 1 with dust, water stains, etc. on the ground, and protecting the storage rack.

[0038] In one embodiment, for the above-mentioned bearing mechanism 3, the bearing mechanism 3 comprises a bearing cylinder 301, which is slidingly mounted on the storage shelf body 1 and located in the placing cavity 2, one end of the bearing cylinder 301 is fixedly mounted with a fixed plate 302, the foamed cotton 9 is fixed on the fixed plate 302, the other end of the bearing cylinder 301 is fixedly mounted with a blocking plate 303, and the bearing cylinder 301 is provided with a sliding groove for sliding of both ends of the limiting plate 6.

[0039] The blocking plate 303 is fixedly mounted with a pulling handle 304 at the end away from the bearing cylinder 301, and two circular clamping blocks 7 are fixedly mounted on the blocking plate 303 at the end close to the bearing cylinder 301, and the blocking plate 303 can block the placing cavity 2.

[0040] The hand driving mechanism 4 comprises a rotating shaft 401, which is rotatably mounted on the blocking plate 303 and extends through the blocking plate 303 to both ends, and both ends of the rotating shaft 401 are fixedly mounted with a driving gear 402 and a hand wheel 403, respectively.

[0041] Both of the advancing mechanisms 5 comprise a driven gear 501, which is rotatably mounted on the blocking plate 303, and both of the driven gears 501 are symmetrically engaged on the driving gear 402, and both of the driven gears 501 are fixedly mounted with a threaded screw rod 502 at the shaft center.

[0042] The other end of the threaded screw rod 502 is rotatably mounted on the fixed plate 302, and both ends of the limiting plate 6 are threadedly mounted on the two threaded screw rods 502, respectively.

[0043] When the PCD cutter needs to be placed, the operator holds the pull handle 304 on the blocking plate 303 and pulls, since the bearing cylinder 301 is slidingly installed in the placing cavity 2 of the storage rack body 1, the bearing cylinder 301 will smoothly slide out of the placing cavity 2, at this time, the PCD cutter is placed in the bearing cylinder 301, one end of the cutter abuts against the foam cotton 9 fixed on the fixed plate 302, then the operator rotates the hand wheel 403, the hand wheel 403 drives the rotating shaft 401 to rotate on the blocking plate 303, then the rotating shaft 401 drives the driving gear 402 to synchronously rotate, since the two driven gears 501 are symmetrically engaged on the driving gear 402 and the driven gear 501 is rotatingly installed on the blocking plate 303, the rotation of the driving gear 402 drives the two driven gears 501 to synchronously and reversely rotate, the threaded rod 502 is fixedly installed at the axis of each driven gear 501, the other end of the threaded rod 502 is rotatingly installed on the fixed plate 302, the two ends of the limiting plate 6 are threadedly installed on the two threaded rods 502 respectively, when the driven gear 501 drives the threaded rod 502 to rotate, the limiting plate 6 moves in the horizontal direction in the sliding groove of the bearing cylinder 301, in the movement process of the limiting plate 6, the foam cotton 9 fixed at one end of the limiting plate 6 also approaches the cutter, with the continuous movement of the limiting plate 6, until the foam cotton 9 on the limiting plate 6 tightly abuts against the two ends of the cutter with the foam cotton 9 on the fixed plate 302, thereby effectively solving the problem that the traditional storage rack lacks effective fixing measures, the cutter is easy to shake, and the cutter precision, service life and production progress are affected, in the process, the two foam cottons 9 are continuously deformed by being extruded, thereby avoiding the direct rigid contact between the cutter and the fixed plate 302 and the limiting plate 6, until the hand wheel 403 cannot be rotated, indicating that the cutter has been stably fixed.

[0044] In one embodiment, for the above-mentioned clamping mechanism 8, the clamping mechanism 8 comprises a support frame 801 fixedly installed on the storage rack body 1, and sliding rods 802 symmetrically slidingly installed at the two ends of the support frame 801, and springs 803 sleeved on the two sliding rods 802.

[0045] Ball bodies 804 are fixedly installed at the ends of the two sliding rods 802 close to each other, one end of the spring 803 is fixedly installed on the ball body 804 and the other end is fixedly installed on the support frame 801, and the two ball bodies 804 are distributed on the two sides of the circular clamping block 7.

[0046] When the carrier cylinder 301 is ready to slide back into the placing cavity 2, the support frame 801 is fixedly installed on the storage frame body 1. When the operator pushes the pull handle 304, the pull handle 304 pushes the blocking plate 303, and during the sliding back of the carrier cylinder 301, the circular clamping blocks 7 symmetrically installed on the blocking plate 303 gradually approach the two spheres 804. The circular clamping blocks 7 first come into contact with the spheres 804 at one end of the sliding rods 802. Due to the shape of the circular clamping blocks 7 and the sliding angle, the circular clamping blocks 7 exert a force on the spheres 804. The force is transmitted to the sliding rods 802 through the spheres 804. Under the action of the force, the two sliding rods 802 symmetrically slide away from each other at the two ends of the support frame 801. Since the two sliding rods 802 are each sleeved with a spring 803, and one end of the spring 803 is fixed to the sphere 804 and the other end is fixed to the support frame 801, the sliding rods 802 slide while compressing the springs 803. The springs 803 store elastic potential energy. As the blocking plate 303 continues to slide in, when the two protrusions at the ends of the circular clamping blocks 7 move past the positions of the spheres 804, the elastic potential energy stored in the springs 803 begins to be released. The restoring force of the two springs 803 pushes the respective spheres 804 and the sliding rods 802 connected thereto to move towards each other until the two spheres 804 tightly abut against the side surfaces of the circular clamping blocks 7. The elastic force of the springs 803 limits the circular clamping blocks 7, ensuring that the carrier mechanism 3 is stably fixed in the placing cavity 2. At this time, the blocking plate 303 blocks the placing cavity 2, thereby avoiding accidental sliding out during transportation.

[0047] It is important to note that the frictional force of the spheres 804 on the circular clamping blocks 7 caused by the elastic force of the springs 803 will far exceed the force required to slide the carrier mechanism 3 as a whole on the storage frame body 1 (but will not excessively hinder the normal pulling out of the carrier mechanism 3). After the carrier mechanism 3 and the PCD cutter slide into the placing cavity 2, even if the carrier mechanism 3 is subjected to a relatively large sliding force due to strong bumps, vibrations, or external collisions during the transportation of the storage frame, the strong elastic force of the springs 803 will drive the spheres 804 to tightly abut against the circular clamping blocks 7. The large frictional force between the spheres 804 and the circular clamping blocks 7 will further hinder the movement of the circular clamping blocks 7. The two forces complement each other, and the combined force is sufficient to counteract any external force that may cause the carrier mechanism 3 to slide, ensuring that the carrier mechanism 3 is always stably fixed in the placing cavity 2. This greatly reduces the possibility of accidental sliding out of the carrier mechanism 3, provides a solid guarantee for the safety of the PCD cutter during transportation and storage, effectively avoids the risk of falling due to the sliding out of the carrier mechanism 3, and effectively maintains the precision and service life of the PCD cutter, ensuring that the production progress is not affected.
