Description

Technical Field

[0001] The utility model relates to the technical field of lathe clamps, in particular to a lathe clamp capable of preventing tool collision. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. It is the most important type of metal cutting machine tool. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to cut rotating surfaces of various sizes and shapes, as well as spiral surfaces; however, during the operation of the lathe, the tool on the lathe is prone to collision with the lathe fixture due to data errors or operator misoperation. If there is a collision between the tool and the lathe fixture, the tool will collide, which is easy to cause damage to the tool. In severe cases, the tool holder that fixes the tool will also fail and be damaged. For this reason, we propose a lathe fixture that prevents tool collision. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a lathe clamp capable of preventing tool collision.

[0004] The technical solution adopted by the utility model to solve the technical problem is a lathe fixture for preventing tool collision, characterized in that it comprises a chuck body, a ring seat for support is assembled on the outer periphery of the chuck body through screws, and a ring cover located on the outer periphery of the chuck body is slidably mounted on the outer periphery of the ring seat, and a bifurcated hole is opened on the outer peripheral surface of the ring cover;

[0005] The outer circumferential surface of the ring cover is equipped with an ear seat for auxiliary support, and there are multiple groups of ear seats. The outer circumferential surface of the ring seat is equipped with earmuffs corresponding to the ear seat, and there are multiple groups of earmuffs. The ear seat is integrally constructed with an adjustable sleeve at one end close to the earmuff, and a sliding seat for adjustment is slidably installed on the inner side of the sleeve. An annular pressure sensor is installed between the ring seat and the sleeve, a cylinder seat for sealing is screwed on the inner side of the ear seat, and a signal transceiver electrically connected to the annular sensor is installed on the inner side of the cylinder seat, and a vertical rod slidably connected to the earmuff is installed on the end of the sliding seat away from the cylinder seat through a screw, and a ring seat located on the outer periphery of the earmuff is screwed on the outer periphery of the vertical rod, and there are two groups of ring seats.

[0006] By adopting the above technical solution, before using the lathe fixture, the ring seat is first installed on the outer periphery of the pneumatic or hydraulic chuck on the lathe surface by screws, and the ring seat and the ring cover are both adapted to the specifications of the chuck body, and at the same time, the bifurcated holes on the surface of the ring cover correspond to the clamping claws on the surface of the chuck body, which facilitates the movement of the clamping claws and clamps the workpiece to be processed, and then the ring cover and the ring seat can be used to protect the chuck body and facilitate disassembly and maintenance;

[0007] When the tool on the lathe moves in error and collides with the clamping claws on the surface of the chuck body or itself, the tool will first touch the ring cover, and the ring cover will slide on the periphery of the ring seat due to the pressure. At the same time, the vertical rod connecting the periphery of the ring seat to the ear sleeve can drive the slide and the sleeve in the bottom sleeve of the ear seat on the periphery of the ring cover to slide against each other, and the sliding of the ring cover synchronously drives the sleeve to move, so that the sleeve and the stationary slide slide against each other. At the same time, the annular pressure sensor on the inside of the sleeve will separate from the slide. Then the annular pressure sensor will transmit the signal to the signal transceiver, which can easily transmit the signal to the PLC control system of the lathe. The PLC control system will immediately control the lathe to stop operating, thereby reducing the damage caused by the collision between the tool and the lathe fixture.

[0008] Specifically, springs are installed between the ear seat and the earmuff and between the slide seat and the tube seat, and a shock absorber located on the inner periphery of the spring is installed inside the sleeve.

[0009] By adopting the above technical solution, the spring between the ear seat and the ear sleeve can push the ear seat back, so that the ear seat can drive the ring cover slidably installed on the outer periphery of the ring seat to move, and because the ring seat and the ring cover will not separate from each other, the vertical rod and the sleeve between the ear seat and the ear sleeve can stably slide relative to each other, and the spring in the sleeve on the bottom side of the ear seat facilitates pushing the slide seat and the cylinder seat, and because the position of the cylinder seat cannot move, the slide seat always maintains mutual abutment and fit with the annular pressure sensor on the inner side of the sleeve, and can also push the cylinder seat back at the same time, so that the cylinder seat drives the ring cover to slide on the outer periphery of the ring seat through the ear seat, and maintains a distance between the two for the ring cover to slide back to its position, and the two sets of springs can cooperate with each other, which is convenient for buffering when the tool touches the ring cover, and the shock absorber between the slide seat and the cylinder seat can also cooperate with the operation of the spring, so that the spring can more stably buffer or push the slide seat back.

[0010] Specifically, a rubber pad for protection is bonded to a side of the ring cover away from the ring seat.

[0011] By adopting the above technical solution, the rubber pad has a certain elasticity, which is convenient for reducing the friction and damage caused by the cutter and the ring cover when they are fitted together.

[0012] Specifically, the outer peripheral surface of the ring seat is provided with arc grooves for connection, and there are multiple groups of arc grooves.

[0013] By adopting the above technical solution, the arc groove on the outer circumference of the ring seat and the arc protrusion on the inner circumference of the ring cover are fitted and connected with each other, so that the ring cover can slide and displace on the outer circumference of the ring seat more stably, and the two can slide closer to each other or away from each other more stably.

[0014] Specifically, a battery body is assembled inside the cartridge seat.

[0015] By adopting the above technical solution, the battery body is located inside the cartridge seat and is convenient for disassembly and assembly, thereby providing power support for the operation of the signal transceiver and the annular pressure sensor screwed on the inside of the cartridge seat, so that both can operate stably and facilitate monitoring of whether the tool touches the chuck body.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of a ring seat, a ring cover and a bifurcated hole. Before using the lathe fixture, the ring seat is first installed on the outer periphery of the pneumatic or hydraulic chuck on the surface of the lathe with screws, and the ring seat and the ring cover are both compatible with the specifications of the chuck body. At the same time, the bifurcated holes on the surface of the ring cover correspond to the clamping claws on the surface of the chuck body, which is convenient for the movement of the clamping claws and clamping the workpiece to be processed. Then, the ring cover and the ring seat can be used to protect the chuck body and facilitate disassembly and maintenance.

[0018] 2. The technical solution of the present application is designed with ear seats, ear sleeves, sleeves, slides, cylinder seats, signal transceivers, annular pressure sensors, vertical rods and ring seats. When an error occurs in the movement of the tool on the lathe and collides with the clamping claws on the surface of the chuck body or itself, the tool will first touch the ring cover, and the ring cover will slide on the outer periphery of the ring seat due to pressure. At the same time, the vertical rod connected to the ear sleeve on the outer periphery of the ring seat can drive the slide and the sleeve in the sleeve on the bottom side of the ear seat on the outer periphery of the ring cover to slide against each other, and the sliding of the ring cover synchronously drives the sleeve to move, so that the sleeve and the stationary slide slide against each other, and at the same time, the annular pressure sensor on the inner side of the sleeve will separate from the slide, and then the annular pressure sensor will transmit the signal to the signal transceiver, which can conveniently transmit the signal to the PLC control system of the lathe, and the PLC control system will immediately control the lathe to stop operating, thereby reducing the damage caused by the collision between the tool and the lathe fixture.

[0027] When the tool on the lathe moves in error and collides with the clamping claws on the surface of the chuck body 1 or itself, the tool will first touch the ring cover 3, and the ring cover 3 will slide on the periphery of the ring seat 2 under pressure, and at the same time, the vertical rod 12 connected to the ear sleeve 6 on the periphery of the ring seat 2 can drive the slide 8 and the sleeve 7 in the bottom side sleeve 7 of the ear seat 5 on the periphery of the ring cover 3 to slide against each other, and the sliding of the ring cover 3 synchronously drives the sleeve 7 to move, so that the sleeve 7 and the stationary slide 8 slide against each other, and at the same time, the annular pressure sensor 11 on the inner side of the sleeve 7 will separate from the slide 8, and then the annular pressure sensor 11 will transmit the signal to the signal transceiver 10, which can easily transmit the signal to the PLC control system of the lathe, and the PLC control system will immediately control the lathe to stop operating, thereby reducing the damage caused by the collision between the tool and the lathe fixture.

[0034] like Figure 2 As shown, a battery body 18 is assembled inside the cartridge holder 9 .

[0035] When in use, the battery body 18 is located inside the cartridge seat 9 and is convenient for assembly and disassembly, so as to provide power support for the operation of the signal transceiver 10 and the annular pressure sensor 11 screwed on the inside of the cartridge seat 9, so that both can operate stably and conveniently monitor whether the tool touches the chuck body 1.

[0036] The working principle and use process of the utility model are as follows: when using, first install the corresponding structural components in the appropriate position.

At the same time, the clamping claw is located in the bifurcation hole 4, and the clamping claw is located on the inner side of the ring cover 3, so that the ring cover 3 can be moved back a certain distance when there is a friction between the tool and the tool, and this distance is the safety line, which is convenient for the tool to stop operating in time when it touches the chuck body 1, and then use the ring cover 3 and the ring The seat 2 can protect the chuck body 1 and facilitate disassembly and maintenance. Then, the sliding distance between the ring seat 2 and the ring cover 3 can be easily adjusted. At the same time, it is only necessary to pull the vertical rod 12 so that the vertical rod 12 can drive the sliding seat 8 to pull the sleeve 7 back, and adjust the distance of the ear sleeve 6 through the outer periphery of the ring seat 2 by adjusting the vertical rod 12. Then, the two groups of ring seats 13 on the outer periphery of the vertical rod 12 can be conveniently rotated so that the two groups of ring seats 13 can be close to each other and abut against each other between the ear sleeves 6, thereby facilitating the fixation of the position where the vertical rod 12 passes through the ear sleeves 6 and adjusting the sliding distance between the ring seat 2 and the ring cover 3. When the tool on the lathe moves with an error and rubs against the clamping claws on the surface of the chuck body 1 or the chuck body 1 itself, the tool will first touch the ring cover 3, and the ring cover 3 will be pressed against the ring The outer periphery of the seat 2 slides, and at the same time, the vertical rod 12 connected to the outer periphery of the ring seat 2 and the ear sleeve 6 can drive the sliding seat 8 and the sleeve 7 in the bottom side sleeve 7 of the outer periphery of the ear seat 5 of the ring cover 3 to slide against each other, and the sliding of the ring cover 3 synchronously drives the sleeve 7 to move, so that the sleeve 7 and the stationary sliding seat 8 slide against each other, and at the same time, the annular pressure sensor 11 on the inner side of the sleeve 7 will be separated from the slide 8, and then the annular pressure sensor 11 will transmit the signal to the signal transceiver 10, and the signal transceiver 10 will conveniently transmit the signal to the PLC control system of the lathe, and the PLC control system will immediately control the lathe to stop operating, thereby reducing the damage caused by the friction between the tool and the lathe fixture. When the tool returns to a safe position, the ring cover 3 on the outer periphery of the ring seat 2 will The ear seat 5 and the ear sleeve 6 can move and reset, and the spring 15 between the ear seat 5 and the ear sleeve 6 can push the ear seat 5 back, so that the ear seat 5 can drive the ring cover 3 on the outer periphery of the ring seat 2 to move, and because the ring seat 2 and the ring cover 3 will not separate from each other, the vertical rod 12 and the sleeve 7 between the ear seat 5 and the ear sleeve 6 can stably slide against each other, and the ring cover 3 can return to its original position. In this process, the spring 15 in the sleeve 7 on the bottom side of the ear seat 5 also facilitates pushing the slide seat 8 and the cylinder seat 9, and because the position of the sleeve 9 cannot be moved, when the ring cover 3 drives the sleeve 7 to move, the slide seat 8 can be reset and abut against the annular pressure sensor 11 on the inner side of the sleeve 7, and the slide seat 8 always maintains abutment and fit between the annular pressure sensor 11 on the inner side of the sleeve 7.At the same time, the spring 15 here can also push back the cartridge seat 9, so that the cartridge seat 9 drives the ring cover 3 to slide on the outer periphery of the ring seat 2 through the ear seat 5, and maintains a distance between the two that allows the ring cover 3 to slide back to its original position.
