[0005] To address the shortcomings of existing technologies, this utility model provides a power tool holder for Swiss-type lathes that is easy to install and disassemble, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power tool holder for a Swiss-type lathe that is easy to install and disassemble, comprising a base and a transmission end. The transmission end is located at the bottom of the base, and an output end is provided on the surface of the base. The output end and the transmission end are connected inside the base via a transmission structure. A tool body is threaded onto the surface of the output end, and a flat head is fixedly installed at the bottom of the transmission end. Several buckles are provided at the bottom of the base, and four screw holes are provided at the top corner of the base. The screw holes extend from the top of the base to the bottom, and screws are fitted inside the screw holes. The surface of the screws is threaded into the inner wall of the screw holes, and several tooth grooves are provided on the top surface of the screws. An installation ring is rotatably installed on the top of the base, and the outer wall of the installation ring is in contact with the surface of the screws. By rotating the installation ring, the edge of the screw is rubbed, causing the screw to rotate and tighten, thus completing the installation of the tool holder.

[0007] Preferably, a torsion cover is rotatably mounted on the inner wall of the mounting ring, a torsion spring is provided between the torsion cover and the mounting ring, a push block is fixedly mounted on the top of the torsion cover, a slide rod is slidably mounted on the inner wall of the mounting ring, a spring is provided between the slide rod and the mounting ring, the slide rod passes through the surface of the mounting ring, an arc block is fixedly mounted on the surface of the torsion cover near the slide rod, the bottom of the arc block contacts the top of the slide rod, a plurality of limiting holes are provided on the top of the seat, the shape of the limiting holes matches the cross-sectional shape of the slide rod, a push plate is fixedly mounted on the surface of the torsion cover, and a baffle is fixedly mounted on the inner wall of the mounting ring. When the torsion cover and the mounting ring are in a stationary state, the slide rod limits the mounting ring in the limiting holes, so that the fixed mounting ring is clamped by the screw.

[0008] Preferably, a support spring is provided between the screw and the base, and a protective cover is fixedly installed on the top of the base near the screw. The support spring lifts up and supports the screw being disassembled, preventing the screw from shaking and rubbing against the screw hole, which would cause wear on the surface threads.

[0009] Preferably, the screw is flush with the mounting ring, and the difference in distance between the top and bottom of the screw and the surface of the base is less than the thickness of the mounting ring, so that the screw is always in contact with the surface of the mounting ring during movement.

[0010] Preferably, the push block is S-shaped, which matches the gripping posture of the operator, conforms to ergonomic design, and is easy to operate.

[0011] Preferably, the cover is aligned with the screw, the cross-sectional shape of the cover matches the screw, and the cross-sectional area is larger than the screw. The cover prevents the screw from falling out or being lost after disassembly, and keeps the disassembled screw in a semi-fixed state, making it easier for workers to install it next time.

[0012] This utility model provides a power tool holder for Swiss-type lathes that is easy to install and disassemble. It has the following advantages:

[0013] (1) This easy-to-install and disassemble Swiss-type machine power tool holder allows the auxiliary positioning docking parts at the bottom of the tool holder to be accurately placed on the surface of the tool holder, completing the initial positioning of the tool holder. Rotating the mounting ring causes the mounting ring to rub against and push the screw to rotate. Because of the thread on the inner wall of the screw hole, the screw moves downward when it rotates and enters the mounting hole on the surface of the tool holder, thus fixing the tool holder on the surface of the tool holder. By rotating the mounting ring, multiple screws can be tightened at the same time to complete the installation of the tool holder. The operation is simple and convenient for workers to install, saving most of the installation process, shortening the preparation time before the Swiss-type machine is run, and improving work efficiency.

[0014] (2) This easy-to-install and disassemble Swiss-type machine tool holder, before the screw cap drives the mounting ring to rotate, the slide rod will spring up and move away from the limiting hole under the elastic force of the spring, so that the limiting hole releases the limiting hole from the mounting ring. Then the screw can be tightened by rotating the mounting ring. After all the screws are installed, the screw cap resets and drives the slide rod to re-enter the limiting hole, fixes the mounting ring, and prevents the mounting ring from continuing to rotate. The screw is clamped to prevent the screw from shaking and affecting the installation stability of the tool holder, thus improving the fixing effect of the tool holder.

[0015] (3) The Swiss-type machine tool holder is easy to install and disassemble. When the tool holder is disassembled, the screw to be disassembled will be supported and lifted by the support spring, which reduces the shaking of the screw and avoids the screw shaking and friction with the inner wall of the screw hole, which will cause thread wear and improve the durability and service life of the screw. At the same time, the cover blocks the screw and prevents the disassembled screw from falling and being lost. The disassembled screw is in a semi-fixed state on the surface of the tool holder, which is convenient for the staff to install next time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a power tool holder for a Swiss-type lathe that is easy to install and disassemble, including a base 1 and a transmission end 2. The transmission end 2 is located at the bottom of the base 1. An output end 3 is provided on the surface of the base 1. The output end 3 and the transmission end 2 are connected inside the base 1 through a transmission structure. A tool body 4 is threaded onto the surface of the output end 3. A flat head 5 is fixedly installed at the bottom of the transmission end 2. Several buckles 6 are provided at the bottom of the base 1. Four screw holes 7 are opened at the top corner of the base 1. The screw holes 7 extend from the top of the base 1 to the bottom of the base 1. A screw 16 is sleeved inside the screw hole 7. The surface of the screw 16 is threaded with the inner wall of the screw hole 7. Several tooth grooves are opened on the top surface of the screw 16. An installation ring 8 is rotatably installed on the top of the base 1. The outer wall of the installation ring 8 is in contact with the surface of the screw 16. By rotating the installation ring 8, the edge of the screw 16 is rubbed, which drives the screw 16 to rotate and tighten the screw 16, thus completing the installation of the tool holder.

[0024] A toggle cover 9 is rotatably mounted on the inner wall of the mounting ring 8. A torsion spring is provided between the toggle cover 9 and the mounting ring 8. A push block 10 is fixedly mounted on the top of the toggle cover 9. A slide rod 11 is slidably mounted on the inner wall of the mounting ring 8. A spring is provided between the slide rod 11 and the mounting ring 8. The slide rod 11 passes through the surface of the mounting ring 8. An arc block 12 is fixedly mounted on the surface of the toggle cover 9 near the slide rod 11. The bottom of the arc block 12 contacts the top of the slide rod 11. Several limiting holes 15 are opened on the top of the seat 1. The shape of the limiting holes 15 matches the cross-sectional shape of the slide rod 11. A push plate 13 is fixedly mounted on the surface of the toggle cover 9. A baffle 14 is fixedly mounted on the inner wall of the mounting ring 8. When the toggle cover 9 and the mounting ring 8 are in a stationary state, the slide rod 11 limits the mounting ring 8 in the limiting holes 15, so that the fixed mounting ring 8 is clamped by the screw 16.

[0025] A support spring 17 is provided between the screw 16 and the base 1. A cover 18 is fixedly installed on the top of the base 1 near the screw 16. The support spring 17 lifts up and supports the screw 16 that has been removed, preventing the screw 16 from shaking and rubbing against the screw hole 7, which would cause wear on the surface threads.

[0026] Screw 16 is flush with mounting ring 8. The difference in distance between the top and bottom of screw 16 and the surface of base 1 is less than the thickness of mounting ring 8. Screw 16 is always in contact with the surface of mounting ring 8 during movement.

[0027] The push block 10 is S-shaped, which matches the gripping posture of the staff, conforms to the ergonomic design, and is easy to operate.

[0028] The cover 18 is aligned with the screw 16. The cross-sectional shape of the cover 18 matches the screw 16, and the cross-sectional area is larger than that of the screw 16. The cover 18 prevents the screw 16 from falling off and being lost, and keeps the screw 16 in a semi-fixed state, making it easier for workers to install it next time.

[0029] Place the tool holder on the surface of the Swiss-type lathe tool post, align the bottom of the base 1 with the power end on the tool post surface, lower the base 1 so that the flat head 5 at the bottom of the transmission end 2 enters the corresponding hole on the power end of the tool post surface, and insert the buckle 6 at the bottom of the base 1 into the corresponding slot on the tool post surface to complete the positioning of the tool holder. The operator uses one hand to slightly fix the tool holder, and the other hand to squeeze the push block 10 on the surface of the twist cover 9. The push block 10 is S-shaped, which matches the operator's hand posture and conforms to ergonomic design, making it easy for the operator to operate. Twist the push block 10 to make it rotate. The rotating push block 10 drives the twist cover 9 to rotate, and the rotating twist cover 9 drives the arc block 12 to rotate. After the arc block 12 rotates, it no longer contacts the slide rod 11, releasing the limit on the slide rod 11. The slide rod 11, which is released from the limit, springs upward away from the limit hole 15 under the action of the spring force, releasing the limit hole 15 for installation. The limit switch of ring 8, and at the same time, when the twist cover 9 continues to rotate, it will drive the push plate 13 to rotate. The rotating push plate 13 contacts the baffle 14, pushing the baffle 14 to drive the mounting ring 8 to rotate. The surface of the rotating mounting ring 8 rubs against the surface of the screw 16, pushing the screw 16 to rotate. The rotating screw 16 moves through the thread on the inner wall of the screw hole 7 into the mounting hole on the surface of the tool holder, so that the tool holder is fixed on the surface of the tool holder, completing the installation of the tool holder. At this time, after the power of the equipment is turned on, the rotation of the power end on the surface of the tool holder will drive the transmission end 2 on the surface of the tool holder to rotate. The rotating transmission end 2 drives the output end 3 to rotate. The rotating output end 3 drives the tool body 4 to rotate to machine the workpiece. The surface of the mounting ring 8 contacts the four screws 16 on the surface of the tool holder. When the mounting ring 8 is rotated, the four screws 16 can be tightened at the same time, which is convenient for the operator to install, eliminates the tedious installation process, shortens the preparation work before the operation of the Swiss-type lathe, and improves work efficiency.

[0030] After the tool holder is installed, the twist cover 9 rotates and resets under the elastic force of the torsion spring. The reset twist cover 9 drives the arc block 12 to reset. During the reset process, the arc block 12 contacts and presses the top of the slide rod 11, causing the slide rod 11 to slide downward. The sliding slide rod 11 enters a certain limiting hole 15 on the surface of the seat body 1. The slide rod 11 entering the limiting hole 15 clamps the mounting ring 8, fixing the mounting ring 8 and clamping the screw 16 to prevent the screw 16 from shaking and affecting the stability of the tool holder installation.

[0031] When the tool holder malfunctions and requires repair, the operator needs to disassemble it. Following the installation steps described above, twisting the cap 9 causes the mounting ring 8 to rotate in the opposite direction. The rotating mounting ring 8 then rubs against and pushes the screw 16 away from the mounting hole on the tool holder surface, bringing it into contact with the tool holder. After the screw 16 is removed, it is lifted and supported by the elastic force of the support spring 17, preventing the screw 16 from shaking and rubbing against the inner wall of the screw hole 7, which would cause wear on the threads of the screw hole 7 and the screw 16 surface, affecting durability. At the same time, due to the obstruction of the cover 18, the removed screw 16 will not fall off and will remain in a semi-fixed state on the tool holder surface, facilitating the operator's next installation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
