TECHNICAL FIELD

[0001] The utility model relates to a cutter clamp especially relates to a planar cutter clamp. BACKGROUND

[0002] The cutter clamp is a tool for fixing and supporting the cutter, which is widely used in mechanical processing, cutting equipment, woodworking processing, metal processing and other fields. Its main function is to firmly fix the cutter on the equipment through the clamping mechanism to ensure the stability and accuracy of the cutter during processing. The cutter clamp is usually composed of multiple components, including fixed plates, clamping blocks, limit pieces and adjusting bolts, which can adapt to different specifications of cutters, such as different lengths, widths and heights.

[0003] The prior art designs a planar cutter clamp for more convenient clamping of planar cutters, such as a planar cutter clamp with application number CN202411610172.0, which includes an upper fixing part, the upper fixing part is installed with a mounting part and a side limiting part, the side limiting part is installed with an upper limiting part, the mounting part includes a top plate, the lower part of the top plate is fixedly installed with an upper connecting block, the lower part of each upper connecting block is integrally provided with a plug, and the upper fixing part includes a fixed plate, the upper part of the fixed plate is integrally provided with a lower connecting block. In the present application, the bolts connecting the fixed plate and the side sliding plate are loosened, the positions of the two side sliding plates are adjusted, the two side sliding plates clamp the two ends of the planar cutter, the planar cutter and the side sliding plate are fixed by tightening the bolts matched with the mounting holes, the spacing of the side sliding plates is adjusted by adjusting the bolts connecting the side sliding plates and the limiting seat, the fixing effect of the planar cutter is improved, and the applicability of the planar cutter of different heights and lengths is improved.

[0004] However, the above-mentioned prior art has the following problems:

[0005] The adjustment process is complicated, the adjustment of the side sliding plate requires the disassembly of too many bolts, the operation is complex, and the work efficiency is reduced; the bolt bearing defect, the side sliding plate is fixed by the first rectangular hole, the second rectangular hole and the bolt, the bolt bears the main bearing role in the clamping process. However, the bolt may be deformed or even broken due to stress concentration in long-term use, which seriously affects the production safety; lack of horizontal limiting measures, the existing design does not take horizontal limiting measures for the bolt, which leads to the possibility of horizontal deviation of the side sliding plate under the influence of machine vibration. This deviation may cause the planar cutter to be unstable, and even cause the planar cutter to fall off, further threatening the production safety.

[0006] In summary, the fixing mode of the side sliding plate in the prior art has problems of complicated adjustment, bolt bearing defects, lack of horizontal limiting, and the like, which may cause bolt deformation, side sliding plate deviation, and flat cutter falling, and the like, and safety hazards, and improvement is urgently needed to improve the stability and safety of the clamp. Practical new type content

[0007] To solve the problems of complicated adjustment, bolt bearing defects, lack of horizontal limiting, and the like, which may cause bolt deformation, side sliding plate deviation, and flat cutter falling, and the like, and safety hazards in the fixing mode of the side sliding plate in the prior art, the utility model provides a flat cutter clamp, and the technical scheme is as follows.

[0008] The clamp comprises an upper mounting block fixedly connected with an external device, a mounting plate fixedly connected below the upper mounting block, a stabilizing rod arranged vertically to the surface of the mounting plate below the mounting plate, a mounting mechanism and a horizontal adjusting mechanism arranged below and on both sides of the stabilizing rod respectively, the mounting mechanism being capable of preliminarily fixing the flat cutter, and the horizontal adjusting mechanism being capable of reinforcing the flat cutter;

[0009] The horizontal adjusting mechanism comprises a through groove opened on the lower end surface of the mounting plate, a pair of sliding plates slidably and suspendingly arranged in the through groove, the sliding plates being arranged on both sides of the stabilizing rod, a locking mechanism arranged between the sliding plates and the through groove, the locking mechanism being capable of locking the sliding plates at specified positions of the through groove, and a release mechanism capable of allowing the mounting plate to freely move;

[0010] A reinforcing mechanism is arranged between the pair of sliding plates and is capable of applying clamping force to the flat cutter in a direction perpendicular to the axis of the stabilizing rod; and a limiting groove is arranged on the side of the sliding plate close to the stabilizing rod to stabilize one side of the flat cutter.

[0011] Further, the cross section of the through groove along the groove direction is T-shaped, horizontal flanges protruding outward are arranged on both sides of the top surface of the sliding plate, and the sliding plate is slidably and suspendingly arranged in the through groove through the flanges on both sides.

[0012] Further, the groove of the through groove is parallel to the top surface of the mounting plate, the stabilizing rod is arranged in the middle of the groove, the groove is divided into two parts of symmetrical length, a plurality of fixed blind holes are uniformly arranged in the through groove along the straight line of the groove, and the axis of the fixed blind hole is perpendicular to the top surface of the mounting plate.

[0013] Furthermore, the locking mechanism includes a movable blind hole on the top surface of the sliding plate. The opening of the movable blind hole is flush with the top surface of the sliding plate, and the axis of the movable hole is perpendicular to the top surface of the sliding plate. A movable pin is coaxially disposed in the movable hole, and a spring is disposed between the movable pin and the inner end face of the movable blind hole. When the movable blind hole and the fixed blind hole are coaxially aligned, the spring pushes the movable pin into the fixed blind hole, preventing the sliding plate from moving horizontally in the through groove. The release mechanism includes a first connecting rod and a second connecting rod movably disposed in the sliding plate. The first connecting rod passes through the end face of the movable blind hole and is coaxially fixedly connected to the movable pin. The first connecting rod moves downwards. The movement can drive the movable pin to move towards the end face of the movable blind hole. One end of the second connecting rod is rotatably connected to the end of the first connecting rod away from the movable pin. A movable shaft is provided in the sliding plate. One part of the body of the second connecting rod is rotatably connected to the movable shaft. The movable surfaces of the first connecting rod and the second connecting rod are coplanar. A clearance groove is provided in the sliding plate. The clearance groove allows the first connecting rod and the second connecting rod to move in space in the sliding plate. When the end of the second connecting rod away from the first connecting rod rotates towards the mounting plate with the movable shaft as the rotation point, it can pull the first connecting rod in the same direction away from the mounting plate, thereby causing the movable pin to retract into the movable hole.

[0014] Furthermore, the installation mechanism includes a fixed clamping plate fixedly disposed below the stabilizing rod. The fixed clamping plate is divided into a front clamping plate and a rear clamping plate, and the fixed clamping plate opens vertically downward. The front clamping plate has several threaded through holes perpendicular to itself. A movable clamping plate is movably disposed between the front clamping plate and the rear clamping plate. A fixing bolt is screwed into the threaded through holes. One end of the fixing bolt is movably connected to the movable clamping plate. Rotating the fixing bolt can push the movable clamping plate horizontally towards the rear clamping plate, so that the movable clamping plate and the rear clamping plate can clamp the flat cutter.

[0015] Furthermore, both the rear clamping plate and the movable clamping plate are provided with a textured anti-slip rubber layer on the side near the flat cutter to prevent the flat cutter from falling off, and the surface of the movable clamping plate that contacts the top surface of the flat cutter is also provided with a buffer pad.

[0016] Furthermore, the reinforcement mechanism includes a threaded fixing tube disposed on one side of the sliding plate, and a movable latch disposed on the other side of the sliding plate. The movable latch is coaxial with the threaded fixing tube, and a threaded rod is movably disposed therein. The movable latch is a bearing structure that allows the threaded rod to rotate. The threaded rod cannot be coaxially translated within the movable latch along its own axis, and one end of the threaded rod can be coaxially screwed into the threaded fixing tube. When the threaded rod is rotated, the two sliding plates can move towards each other, thereby clamping the planar cutter.

[0017] This invention offers the following advantages: Addressing the lack of portability in adjusting the sliding plate position in existing technologies, this invention utilizes a T-shaped groove and locking mechanism to allow the sliding plate to slide and lock in position without disassembling bolts, enabling rapid alignment adjustment of the flat cutter. Regarding bolt load-bearing issues, this invention employs an inverted T-shaped groove and flange to distribute the load on the sliding plate, improving the problem of concentrated bolt stress. Addressing side sliding plate misalignment and flat cutter detachment, the limiting groove of the sliding plate engages with the cutter protrusion, combined with a reinforcing mechanism for active lateral clamping. This dual constraint ensures stability in the cutting direction, resolving the risk of lateral displacement. Simultaneously, the anti-slip rubber layer and buffer pad increase frictional resistance, further preventing flat cutter slippage and enhancing safety redundancy. Attached Figure Description

[0023] The present invention will now be described in conjunction with the accompanying drawings: Figure 1 As shown, the fixture includes an upper mounting block 1 that is fixedly connected to an external device. A mounting plate 2 is fixedly connected below the upper mounting block 1. A stabilizing rod 3 is provided below the mounting plate 2 and perpendicular to its surface. A mounting mechanism and a lateral adjustment mechanism are respectively provided below and on both sides of the stabilizing rod 3. The mounting mechanism can initially fix the flat cutter 4, and the lateral adjustment mechanism can reinforce the flat cutter 4.

[0024] like Figure 1As shown, the lateral adjustment mechanism includes a through groove 5 opened on the lower end face of the mounting plate 2. A pair of sliding plates 6 are slidably suspended in the through groove 5, and the pair of sliding plates 6 are respectively arranged on both sides of the stabilizing rod 3. A locking mechanism is provided between the sliding plate 6 and the through groove 5. The locking mechanism can lock the sliding plate 6 in a designated position in the through groove 5. A release mechanism is also provided to allow the mounting plate 2 to move freely.

[0025] like Figure 2 As shown, preferably, the slots on both sides of the through groove 5 are provided with detachable limiting baffles 27, which can limit the sliding plate 6.

[0026] like Figure 1 As shown, a reinforcing mechanism is provided between the pair of sliding plates 6, which can apply a clamping force to the planar cutter 4 in a direction perpendicular to the axis of the stabilizing rod 3. Figure 1 As shown, preferably, the reinforcement mechanism includes a threaded fixing tube 23 disposed on one side of the sliding plate 6, and a movable bayonet 24 disposed on the other side of the sliding plate 6. The movable bayonet 24 is coaxial with the threaded fixing tube 23, and a threaded rod 25 is movably disposed therein. The movable bayonet 24 is a bearing structure that allows the threaded rod 25 to rotate. The threaded rod 25 cannot be coaxially translated along its own axis in the movable bayonet 24, and one end of the threaded rod 25 can be coaxially screwed into the threaded fixing tube 23. When the threaded rod 25 is rotated, the two sliding plates 6 can move towards each other, thereby clamping the flat cutter 4.

[0027] like Figure 1 As shown, the sliding plate 6 is provided with a limiting groove 7 on the side near the stabilizing rod 3 to stabilize one side of the flat cutter 4, and the flat cutter 4 is provided with protrusions 8 on both sides that match the limiting groove 7.

[0028] like Figure 3 As shown, preferably, the cross-section of the through groove 5 along the channel direction is T-shaped, and the top surface of the sliding plate 6 is provided with horizontally outward protruding flanges 9 on both sides, so that the sliding plate 6 can be slidably suspended in the through groove 5 through the flanges 9 on both sides.

[0029] like Figure 1 , Figure 2 As shown, preferably, the channel of the through groove 5 is parallel to the top surface of the mounting plate 2, and the stabilizing rod 3 is set in the middle of the channel, dividing the channel into two parts of symmetrical length. A plurality of fixing blind holes 10 are evenly opened along the straight line of the channel in the through groove 5, and the axis of the fixing blind holes 10 is perpendicular to the top surface of the mounting plate 2.

[0030] like Figure 1 , Figure 2As shown, preferably, the locking mechanism includes a movable blind hole 11 opened on the top surface of the sliding plate 6, and the axis of the movable hole is perpendicular to the top surface of the sliding plate 6. A movable pin 12 is coaxially movably disposed in the movable hole. A spring 13 is disposed between the movable pin 12 and the inner end face of the movable blind hole 11. When the movable blind hole 11 is coaxially aligned with the fixed blind hole 10, the spring 13 pushes the movable pin 12 into the fixed blind hole 10, thereby fixing the sliding plate 6. The release mechanism includes a first connecting rod 14 and a second connecting rod 15 movably disposed in the sliding plate 6. The first connecting rod 14 passes through the end face of the movable blind hole 11 and is coaxially fixedly connected to the movable pin 12. The axial downward movement of the first connecting rod 14 can drive the movable pin 12. Pin 12 retracts into the movable blind hole 11. One end of the second connecting rod 15 is rotatably connected to the end of the first connecting rod 14 away from the movable pin 12. The body of the second connecting rod 15 is rotatably connected to the movable shaft 16 provided in the sliding plate 6. The movable surfaces of the first connecting rod 14 and the second connecting rod 15 are coplanar. A clearance groove 17 is provided in the sliding plate 6. The clearance groove 17 provides the movable space for the first connecting rod 14 and the second connecting rod 15 in the sliding plate 6. When the end of the second connecting rod 15 away from the first connecting rod 14 rotates towards the mounting plate 2 with the movable shaft 16 as the rotation point, it can pull the first connecting rod 14 in the same direction away from the mounting plate 2, thereby causing the movable pin 12 to retract into the movable hole. In addition, the clearance groove 17 penetrates the outer wall of the sliding plate 6 away from the stabilizing rod 3 to form a clearance opening. The second linkage rod 15 protrudes from the outer wall of the sliding plate 6 through the clearance opening. A fixing block 26 can be inserted into the gap between the second linkage rod 15 and the clearance opening, so that the second linkage rod 15 cannot move, thereby locking the movable pin 12.

[0031] like Figure 4 As shown, preferably, the installation mechanism includes a fixed clamping plate fixedly disposed below the stabilizing rod 3. The fixed clamping plate is divided into a front clamping plate 18 and a rear clamping plate 19, and the fixed clamping plate opens vertically downward. The front clamping plate 18 has several threaded through holes 21 perpendicular to itself. A movable clamping plate 20 is movably disposed between the front clamping plate 18 and the rear clamping plate 19. A fixing bolt 22 is screwed into the threaded through hole 21. One end of the fixing bolt 22 is movably connected to the movable clamping plate 20. Rotating the fixing bolt 22 can push the movable clamping plate 20 horizontally towards the rear clamping plate 19, so that the movable clamping plate 20 and the rear clamping plate 19 can clamp the flat cutter 4.

[0032] like Figure 4 As shown, preferably, both the rear clamping plate 19 and the movable clamping plate 20 are provided with a textured anti-slip rubber layer 28 on the side near the flat cutter 4 to prevent the flat cutter 4 from falling off, and the surface of the movable clamping plate 20 that contacts the top surface of the flat cutter 4 is also provided with a buffer pad.

[0033] The method of using this utility model is as follows: Insert the flat cutter 4 into the vertically downward opening of the fixed clamping plate, aligning the protrusions 8 on both sides with the limiting grooves 7 of the sliding plate 6. Rotate the fixing bolt 22 to push the movable clamping plate 20 horizontally towards the rear clamping plate 19, clamping the flat cutter 4 through the horizontal anti-slip rubber layer 28 and the buffer pad. Then move the two sliding plates 6 to the desired position along the through groove 5 of the mounting plate 2. When the movable blind hole 11 of the sliding plate 6 is aligned with the fixed blind hole 10 of the through groove 5, the spring 13 pushes the movable pin 12 into the hole to complete the locking. At this time, the limiting groove 7 and the cutter protrusions 8 are completely engaged. When the position of the sliding plate 6 needs to be adjusted, press the end of the second linkage rod 15 to make it rotate around the movable shaft 16, which drives the first linkage rod 14 to pull the movable pin 12 away from the fixed blind hole 10. The unlocked sliding plate 6 can then slide along the T-shaped through groove 5. Finally, rotate the threaded rod 25 of the reinforcement mechanism to screw it into the threaded fixing tube 23, which drives the two sliding plates 6 to move towards each other and applies a lateral clamping force to the flat cutter 4 in the direction perpendicular to the axis of the stabilizing rod 3, thus completing the stable fixation of the flat cutter 4. Through the above operations, the installation, position adjustment and multi-directional reinforcement of the flat cutter 4 can be quickly achieved.
