DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] See also Figure 1-Figure 4The present invention provides a technical solution: a spring washer cutting machine comprises a bottom plate 1, and anchor holes 2 are provided at four corners of the upper end surface of the bottom plate 1. By providing the anchor holes 2 on the bottom plate 1, the bottom plate 1 can be conveniently fixed at a desired position. A T-slot 3 is provided at the middle position of the upper end surface of the bottom plate 1, and a movable plate 5 is installed on the upper side of the T-slot 3. A T-bar 4 is fixed at the middle position of the lower end surface of the movable plate 5. The T-bar 4 is inserted in the T-slot 3. When the movable plate 5 is pushed, the movable plate 5 drives the T-bar 4 to slide along the T-slot 3, so as to facilitate changing the position of the movable plate 5. An insertion rod 16 is installed on the upper side of the movable plate 5, and two groups of support rods 6 are fixed on the lower side of the outer surface of the left end of the insertion rod 16. The lower ends of the two groups of support rods 6 are fixed on the left side of the upper end surface of the movable plate 5, and the support rod 6 serves to connect the insertion rod 16 and the movable plate 5 The role of the insert rod 16 is provided with a knife groove 17 on the upper side of the annular side surface, and a plurality of threaded blind holes 9 are equidistantly provided on the upper end surface of the movable plate 5, and two groups of U-shaped frames 8 are installed on the upper side of the movable plate 5. The lower end surfaces of the two groups of U-shaped frames 8 are provided with circular holes 21, and the fastening bolts 7 are inserted in the circular holes 21. The fastening bolts 7 pass through the circular holes 21 and are engaged in the threaded blind holes 9 through threads. The upper end surfaces of the two groups of U-shaped frames 8 are provided with threaded through holes 20, and the two groups of threaded through holes 20 are engaged with threaded rods 15. The outer surfaces of the upper ends of the two groups of threaded rods 15 are sleeved with rolling bearings 18, and the upper ends of the two groups of rolling bearings 18 are installed with sleeves 14. The outer surface of the right end of the sleeve 14 is installed with a clamping plate 19 by screws. The outer ring of the rolling bearing 18 is fixedly connected to the sleeve 14, and the pull rods 10 are inserted in the two groups of sleeves 14. The upper end surface of the bottom plate 1 A support plate 13 is installed at the middle position of the rear side, a motor 12 is installed at the upper end of the support plate 13, a grinding wheel 11 is installed at the output end of the motor 12, and the grinding wheel 11 is inserted in the knife groove 17. The spring washer coil 22 to be cut is sleeved on the insertion rod 16, and then the pull rod 10 is passed between the two groups of sleeves 14, and the pull rod 10 is passed through the spring washer coil 22. The spacing between the two groups of sleeves 14 is adjusted according to the length of the spring washer coil 22 until the clamping plates 19 on the two groups of sleeves 14 are in contact with the spring washer coil 22, and then the fastening bolts 7 are passed through the round holes 21 and screwed into the corresponding threaded blind holes 9 to complete the fixation of the U-shaped frame 8. By changing the position of the U-shaped frame 8, the clamping range of the spring washer coil 22 is expanded. When the thickness of the clamping plate 19 does not meet the requirements, the clamping plate 1 9 is removed from the sleeve 14, and a clamping plate 19 of suitable thickness is replaced. When the threaded rod 15 is screwed, the threaded rod 15 rotates in the threaded through hole 20, and at the same time, the threaded rod 15 drives the sleeve 14 to move downward. Since the threaded rod 15 is rollingly connected with the sleeve 14 through the rolling bearing 18, the sleeve 14 does not rotate with the rotation of the threaded rod 15. During the downward movement of the sleeve 14, the pull rod 10 is driven to move downward, so that the pull rod 10 pulls the spring washer coil 22 downward, and then the pull rod 10, the insertion rod 16 and the clamping plate 19 work together to limit the position of the spring washer coil 22. Then, the circuit between the motor 12 and the external power supply is turned on, and the motor 12 drives the grinding wheel 11 to rotate, pushing the movable plate 5, and then the grinding wheel 11 moves relative to the insertion rod 16 in the knife groove 17.The rotating grinding wheel 11 cuts the spring washer coil 22.

[0018] Two groups of fastening bolts 7 are installed, and two groups of circular holes 21 are opened on the lower end surface of the U-shaped frame 8. The two groups of fastening bolts 7 are respectively inserted into the two groups of circular holes 21. The two groups of fastening bolts 7 are used to connect the U-shaped frame 8 and the movable plate 5, thereby improving the reliability of the connection between the U-shaped frame 8 and the movable plate 5.

[0019] A handle is installed on the outer surface of the lower end of the threaded rod 15, and a plastic ball is sleeved on the other end of the handle. The handle is installed on the threaded rod 15 to facilitate twisting the threaded rod 15. The plastic ball is installed on the handle to prevent one end of the handle from scratching the palm.

[0020] The lower end of the support rod 6 is fixed to the chassis, and the chassis is fixedly connected to the movable plate 5 by bolts. The chassis is installed on the movable plate 5 by threads to achieve the installation of the position of the support rod 6.

[0021] The annular side surface of the pull rod 10 is wrapped with a rubber sleeve, and a plurality of groups of convex points are evenly arranged on the outer surface of the rubber sleeve. The rubber sleeve is wrapped on the pull rod 10 and the convex points are processed on the rubber sleeve to reduce the probability of slipping between the pull rod 10 and the spring washer coil 22.

[0022] The above embodiments are only preferred implementations of the present invention, so all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
