Description

Technical Field

[0001] The utility model relates to the field of CNC vertical lathes, and more specifically, to a multifunctional tool holder for CNC vertical lathes. Background Art

[0002] A CNC vertical lathe is a machine tool that is controlled by a digital program. It is mainly used to process rotating parts, such as discs, rings and cylinders. Compared with traditional vertical lathes, CNC vertical lathes use a computer numerical control (CNC) system to control the tool's motion trajectory, speed, position and other parameters during the processing, thereby achieving high-precision and high-efficiency automated processing. The tool holder is a structure used to clamp the tool on a CNC vertical lathe.

[0003] In the Chinese patent application number 201420593429.1, a multifunctional tool clamp for CNC vertical lathe is disclosed. The tool clamp disclosed in the disclosure can be suitable for clamping tool bodies of different sizes by setting a plurality of screw holes at different positions, thereby increasing the scope of application. However, when installing the tool body, the tool clamp disclosed in the disclosure needs to use a first L-shaped clamp body and a second L-shaped clamp body to clamp the tool body. When the first L-shaped clamp body and the second L-shaped clamp body are close to clamp the tool body, the first L-shaped clamp body and the second L-shaped clamp body are prone to tilt, which will cause the tool to be installed crookedly, and it is not convenient for the bolt to be quickly penetrated and screwed, and it is easy to get misaligned and stuck.

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0028] Figure 1 and Figure 2 All of them are schematic diagrams of the overall structure of the utility model. As shown in the figure, the multifunctional tool clamp for CNC vertical lathe includes a first clamping plate 1 and a second clamping plate 4. The first clamping plate 1 and the second clamping plate 4 can be close to or away from each other through a connecting member. The connecting member is preferably a bolt member. The distance between the two is adjusted by the tightness of the screwing of the bolt and the nut to adapt to the installation of different tool bodies and realize multifunctional installation. The top ends of the first clamping plate 1 and the second clamping plate 4 are both connected to a mounting handle 6. The top ends of the mounting handle 6 are fixed with a mounting plate 7. The mounting plate 7 is provided with a mounting hole 8. The mounting hole 8 is used to The mounting plate 7 can mount the tool holder on the spindle tool holder of the CNC vertical lathe, and a plurality of first screw holes 3 are equidistantly provided in the middle of the outer walls of the first clamping plate 1 and the second clamping plate 4, and a plurality of second screw holes 11 are provided at the upper and lower ends of the outer walls of the first clamping plate 1 and the second clamping plate 4. Secondly, a positioning assembly is also provided between the first clamping plate 1 and the second clamping plate 4. The positioning assembly is preferably provided with four groups, which are located at the corners of the opposite surfaces of the first clamping plate 1 and the second clamping plate 4, and the arrangement of the positioning assembly is used to increase the linearity of the first clamping plate 1 and the second clamping plate 4 during the clamping process to prevent misalignment.

[0029] Among them, see Figure 3 and Figure 5As shown, the positioning assembly includes a positioning hole 2 and a positioning member 5. The positioning hole 2 is opened through the corner of the first clamp plate 1. The positioning member 5 includes a positioning rod 51. One end of the positioning rod 51 is connected to the corner of the second clamp plate 4 facing the first clamp plate 1, and the positioning rod 51 can pass through the positioning hole 2.

[0030] participate Figure 4 and Figure 5 As shown, the positioning member 5 also includes a convex ring 52 and a spring 53. The spring 53 is sleeved on the outside of the positioning rod 51, and the convex ring 52 is fixed to the outside of the positioning rod 51. A groove 12 is opened at one end of the positioning hole 2 facing the second clamping plate 4, and the spring 53 is connected between the inside of the groove 12 and the convex ring 52.

[0031] The inner diameter of the groove 12 is larger than the inner diameter of the positioning hole 2, the outer diameter of the spring 53 is smaller than the inner diameter of the groove 12, and the outer diameter of the spring 53 is larger than the inner diameter of the positioning hole 2, so that the spring 53 is always in the groove 12 and will not pass through the positioning hole 2, and in the natural state of the spring 53, part of the spring 53 is outside the positioning hole 2.

[0032] Through the above technical solution:

[0033] When the cutter body is installed between the first clamping plate 1 and the second clamping plate 4, the positioning rod 51 always passes through the positioning hole 2, which can ensure the parallelism of the first clamping plate 1 and the second clamping plate 4 and avoid skewing, which is conducive to the rapid tightening of the subsequent bolts and avoids the misalignment of the bolts.

[0034] Among them, when the first clamping plate 1 and the second clamping plate 4 are close to each other, the spring 53 connected to the convex ring 52 is squeezed and retracted into the groove 12. The elastic force generated can facilitate rapid separation during subsequent disassembly to avoid jamming between the first clamping plate 1 and the knife body and between the second clamping plate 4 and the knife body caused by over-tightening of the bolts.

[0035] In addition, see Figure 1-Figure 3 As shown, a first mounting groove 9 is provided in the middle of one side opposite to the first clamping plate 1 and the second clamping plate 4 , and a second mounting groove 10 is provided at the middle upper end and the middle lower end of one side opposite to the first clamping plate 1 and the second clamping plate 4 .

[0036] Through the above, the first installation groove 9 and the second installation groove 10 can be arranged to match the installation parts of different blade bodies, so as to improve the accuracy and stability of the blade body installation.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
