Description

Technical Field

[0001] This utility model belongs to the technical field of machine tool processing equipment, and more specifically, it relates to a tool holder support plate. Background Technology

[0002] The tool post is a crucial component of a CNC lathe. Depending on its function, the number of tools that can be mounted on the tool post on a CNC lathe is generally 4, 6, 8, 10, 12, 20, or 24, and some CNC lathes can accommodate even more. The tool post structure is typically rotary, with tools mounted circumferentially. It can hold radial turning tools, axial turning tools, drills, and boring tools. Turning machining centers can also mount axial and radial end mills. A few CNC lathes have a straight-line tool post, with tools mounted in a straight line.

[0003] In existing technologies, while existing machine tool turrets can achieve relatively quick fixing and replacement of various tools during machine tool processing, the replacement speed is still relatively low. That is, during the fixing or replacement of tools, the operator needs to use tools to loosen or tighten each fixing bolt, rather than loosening or tightening multiple fixing bolts at the same time. This increases the time for tool replacement and fixing, thereby reducing the efficiency of machine tool processing, which in turn reduces the effectiveness and efficiency of the machine tool turret.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tool holder plate in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a tool holder support plate, which solves the problem that existing machine tool tool holders cannot quickly and conveniently clamp and fix tools.

[0006] The purpose and function of this utility model's tool holder support plate are achieved by the following specific technical means:

[0007] A tool holder plate, comprising:

[0008] A base and multiple clamping mechanisms arranged in a circumferential array on the base;

[0009] The clamping mechanism includes a clamping groove, a clamping plate disposed in the clamping groove, a guide member that guides the movement of the clamping plate, a telescopic member that drives the clamping plate to extend and retract, and a locking member that temporarily fixes the clamping plate.

[0010] Preferably, the clamping mechanism further includes a first clamping block and a second clamping block, and the guiding member includes at least two guide holes disposed in the second clamping block and a guide rod slidably connected to the guide holes, one end of the guide rod being fixedly connected to the clamping plate.

[0011] Preferably, the outer end of the guide hole is provided with a countersunk hole, and the outer end of the guide rod is provided with a retaining protrusion, which is disposed outside the countersunk hole.

[0012] Preferably, a spring is provided inside the countersunk hole, with one end of the spring abutting against the inner end of the countersunk hole and the other end of the spring abutting against the retaining protrusion.

[0013] Preferably, the telescopic component includes a threaded block I fixedly connected to the second locking block and a screw rod I threadedly connected to the threaded block I, one end of the screw rod I being rotatably connected to the clamping plate.

[0014] Preferably, the locking member includes a threaded block two fixedly connected to the clamping plate and a screw two threadedly connected to the threaded block two.

[0015] Preferably, the outer ends of the screw are fixedly connected with handles.

[0016] Preferably, the base surface is provided with a plurality of slots, the slots are provided corresponding to the clamping mechanism, the slots are provided on the bottom wall of the clamping slot, and a magnet is fixedly connected in the slot.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The base of this invention facilitates the circular array arrangement of multiple clamping mechanisms, while the sliding clamping plate can move quickly and easily under the action of the telescopic component. Furthermore, the clamping plate is fixed in a suitable position under the locking action of the locking component, thereby clamping and fixing the cutter head. Thus, the cutter head can be quickly fixed under the combined action of the telescopic component and the locking component. Compared with the traditional method of fixing with multiple bolts, the clamping and fixing efficiency is significantly improved, making cutter head replacement more convenient and quick.

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides a tool holder support plate, comprising:

[0031] A base 1 and a plurality of clamping mechanisms 2 arranged in a circular array on the base 1;

[0032] The clamping mechanism 2 includes a clamping groove 20, a clamping plate 23 disposed in the clamping groove 20, a guide member that guides the movement of the clamping plate 23, a telescopic member 24 that drives the clamping plate 23 to extend and retract, and a locking member 25 that temporarily fixes the clamping plate 23.

[0033] In this embodiment, the base 1 facilitates the circular array arrangement of multiple clamping mechanisms 2, while the sliding clamping plate 23 can move quickly and easily under the action of the telescopic member 24. Furthermore, the clamping plate 23 is fixed in a suitable position under the locking action of the locking member 25, thereby clamping and fixing the cutter head 4. Thus, under the cooperative action of the telescopic member 24 and the locking member 25, the cutter head 4 can be quickly fixed. Compared with the traditional method of fixing with multiple bolts, the clamping and fixing efficiency is significantly improved, making the replacement of the cutter head 4 more convenient and quick.

[0034] The clamping mechanism 2 also includes a first clamping block 21 and a second clamping block 22. The guide component includes at least two guide holes 220 disposed in the second clamping block 22 and a guide rod 26 slidably connected to the guide holes 220. One end of the guide rod 26 is fixedly connected to the clamping plate 23.

[0035] The guide components allow the clamping plate 23 to move more smoothly and without deviation, ensuring that the clamping force on the cutter head 4 is uniform.

[0036] The outer end of the guide hole 220 is provided with a countersunk hole 221, and the outer end of the guide rod 26 is provided with a retaining protrusion 260, which is located outside the countersunk hole 221.

[0037] The locking protrusion 260 serves to limit the movement of the guide rod 26, preventing it from sliding out along the guide hole 220.

[0038] A spring 27 is installed inside the countersunk hole 221. One end of the spring 27 abuts against the inner end of the countersunk hole 221, and the other end of the spring 27 abuts against the retaining protrusion 260.

[0039] The spring 27 is configured to provide a certain elastic force for the movement of the clamping plate 23. Since the elastic force of the spring 27 drives the clamping plate 23 to approach the second locking block 22, the adjustment of the clamping plate 23 when it is retracted is more effortless.

[0040] The telescopic component 24 includes a threaded block 241 fixedly connected to the second locking block 22 and a screw 242 threadedly connected to the threaded block 241. One end of the screw 242 is rotatably connected to the clamping plate 23.

[0041] The locking component 25 includes a threaded block 251 fixedly connected to the clamping plate 23 and a screw 252 threadedly connected to the threaded block 251. The distance between the screw 252 and the second locking block 22 is adjustable and can be adjusted according to different needs.

[0042] The outer end of screw 252 is fixedly connected to a handle 253.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In use, the cutting head 4 is first placed in the clamping groove 20, and then the screw 242 is turned to bring the clamping plate 23 closer to the inner end face of the first locking block 21, thereby clamping and fixing the cutting head 4 with the first locking block 21 and the clamping plate 23. Then, by turning the handle 253, the screw 252 is rotated, and the inner end of the screw 252 abuts against the upper surface of the second locking block 22, thereby fixing the clamping plate 23. The other clamping mechanisms 2 fix their respective cutting heads 4 in sequence. If it is necessary to remove the cutting head 4, simply turn the handle 253 to move the lower end of the screw 252 away from the upper surface of the second locking block 22, and then turn the screw 242 to move the clamping plate 23 away from the inner end face of the first locking block 21, so that the cutting head 4 can be easily removed. Example

[0045] The remaining features are the same as in Embodiment 1, except that the base 1 in this embodiment has multiple slots 10 on its surface. The slots 10 are correspondingly arranged with the clamping mechanism 2. The slots 10 are located on the bottom wall of the clamping groove 20, and a magnet 3 is fixedly connected inside the slot 10. The cutter head 4 is made of iron, so that the cutter head 4 can be magnetically attracted to the magnet 3. The cutter head 4 is initially positioned by magnetic attraction, and then fixed by the telescopic member 24 and the locking member 25. Even if the cutter head 4 is in a vertical position, it can be easily fixed.

[0046] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
