Description

Technical Field

[0001] This utility model relates to the field of grinding machine fixture equipment technology, specifically a clamping mechanism for a five-axis grinding machine. Background Technology

[0002] A five-axis grinder is a grinding machine with five motion axes, typically including three linear axes and two rotary axes. These five axes can work together simultaneously, enabling high-precision grinding of workpieces with complex shapes. The clamping mechanism of a five-axis grinder is a component that ensures the accurate positioning and secure fixation of the workpiece during processing. There are various types, one of which is the vise clamping mechanism. However, the vise clamping mechanisms of existing five-axis grinder equipment cannot quickly and conveniently assemble zero-point quick-release plates of different specifications, thus hindering flexible clamping operations to meet different processing requirements.

[0003] A five-axis fixture, as disclosed in announcement number CN217194848U, includes: a mounting plate, a fixed base, and a slide. The fixed base is mounted on the top of the mounting plate, and the top of the fixed base has an electroplated layer. Two sets of sliders are located at the bottom inside the fixed base. Two sets of slides are movably mounted on both sides of the fixed base through the cooperation of the sliders and sliding grooves. The slides have a reinforced coating on the outside. A mounting beam is installed inside the fixed base, and a bearing is installed inside the mounting beam. This invention utilizes the excellent rust prevention and chemical corrosion resistance of the reinforced coating on the outside of the slides, making the slides less susceptible to chloride corrosion and stress fracture during long-term use, greatly mitigating metal corrosion. Furthermore, the reinforced coating has excellent non-adhesive properties, making it easier to remove solutions or dirt during production operations, saving maintenance time and improving work efficiency. However, this fixture cannot be easily and quickly installed and fixed with quick-release plates of different specifications during use. Utility Model Content

The upper adapter cover 21 has a rotating seat upper through hole 28 through the inner side.

[0030] The above solution allows for the quick positioning and installation of the limiting adapter 2 inside the clamping and fixing seat 1 by using the mutually compatible positioning dovetail blocks 12 and positioning dovetail grooves 25. Furthermore, the quick-installation rivets 5, which are slidably installed in the long limiting grooves 14 and short limiting grooves 15 of the rivets, allow for flexible adjustment of the spacing between them, thereby adapting to different specifications of zero-point quick-installation plates.

[0031] Reference Figure 6 The chuck slider 3 includes a cross chuck slider 30. The cross chuck slider 30 has a bidirectional lead screw threaded hole 31 through the middle. A chuck positioning boss 32 is fixedly installed at one end of the cross chuck slider 30. The chuck positioning boss 32 has a chuck fixing threaded hole 33 inside. There are two sets of both the chuck positioning boss 32 and the chuck fixing threaded hole 33.

[0032] Reference Figure 7 The clamping chuck 4 includes a clamping chuck body 40, a vertical clamping groove 41 is provided on one side of the clamping chuck body 40, a dovetail clamping head 42 is fixedly provided on the upper end of the clamping chuck body 40, a clamping tooth groove 43 is provided on the side of the dovetail clamping head 42, a chuck countersunk hole 44 is provided inside the clamping chuck body 40 and the dovetail clamping head 42, a chuck positioning groove 45 is provided at one end of the chuck countersunk hole 44, the chuck countersunk hole 44 and the chuck positioning groove 45 pass through the clamping chuck body 40 and the dovetail clamping head 42, and there are two sets of both the chuck countersunk hole 44 and the chuck positioning groove 45.

[0033] By adopting the above solution, the clamping and fixing seat 1 can be firmly locked by sliding the quick-release rivet 5 to the appropriate position and inserting it into the locking hole of the zero-point quick-release plate rivet. By setting the mutually compatible chuck positioning boss 32 and chuck positioning groove 45, the clamping chuck 4 and chuck slider 3 can be positioned and installed more quickly. This makes it easier to disassemble and replace the clamping chuck 4. When clamping, the clamping chuck 4 can be rotated 180 degrees to be installed, so as to adapt to different clamping needs and make quick adjustments.

[0034] Reference Figure 8The quick-release rivet 5 includes a beveled T-shaped slider 50 and a quick-release rivet head 51. One end of the beveled T-shaped slider 50 has a rivet threaded hole 52 inside, and one end of the quick-release rivet head 51 is fixedly provided with a rivet threaded rod 53. The rivet threaded hole 52 and the rivet threaded rod 53 are fitted together by screws.

[0035] Reference Figure 9 The threaded screw 6 includes a double-ended bidirectional threaded screw 60. One end of the double-ended bidirectional threaded screw 60 has an internal hexagonal hole 61. A limit transition bearing 62 is fixedly installed at one end of the middle of the double-ended bidirectional threaded screw 60. There are two sets of both the internal hexagonal hole 61 and the limit transition bearing 62.

[0036] The working principle of this utility model is as follows: In use, the positioning dovetail block 12 and positioning dovetail groove 25 that are mutually compatible can quickly position and install the limiting adapter 2 inside the clamping fixing seat 1. The quick-installing rivets 5, which are slidably located in the long limiting slide groove 14 and the short limiting slide groove 15 of the rivet, can flexibly adjust the distance between them to adapt to different specifications of zero-point quick-installing plates. When the quick-installing rivet 5 slides to the appropriate position, it is inserted into the rivet locking hole of the zero-point quick-installing plate and locked at the same time, so that the clamping fixing seat 1 can be firmly locked. By setting the clamping head positioning boss 32 and the clamping head positioning groove 45 that are mutually compatible, the clamping head 4 and the clamping head slider 3 can be positioned and installed more quickly. This makes it easier to disassemble and replace the clamping head 4. When clamping, the clamping head 4 can be rotated 180 degrees to install, so as to adapt to different clamping needs and make quick adjustments.
