Double ended asynchronous cycle loose clamp device and method

Abstract

This invention discloses a dual-head asynchronous cyclic clamping and releasing device and method, relating to the field of machine tool technology. It solves the technical problem of low processing efficiency caused by the need to clamp and release machine tools at different positions. The key technical solution is that the forward movement of the mandrel causes the locking element to drive the rotating spindle in a forward motion, thereby moving the guide groove to the limit rod; then, the reverse movement of the mandrel causes the compression spring to drive the rotating spindle in a reverse motion, thereby moving the first or second limit groove to the limit rod. Through the forward and reverse movements of the mandrel, the guide groove and limit groove on the rotating spindle can move to the limit rod, thus achieving synchronous clamping and releasing of the mandrel and the base head. This avoids the time wasted by the need for clamping and releasing at different positions in the traditional production process, thereby improving the processing efficiency of the product.

Description

Technical Field

[0001] This application relates to the field of machine tool technology, and in particular to a dual-head asynchronous cyclic clamping device and method. Background Technology

[0002] In existing devices, the machine tool base cannot accurately clamp and release with the turret during rapid reciprocating motion. This results in the machine tool base needing to be clamped and released at different positions during movement, leading to wasted time and processing efficiency that does not meet customer requirements. Summary of the Invention

[0003] This application provides a dual-head asynchronous cyclic clamping and loosening device and method. Its technical purpose is to enable the machine tool base to quickly clamp and separate along with the turret during the movement process, thereby improving the processing efficiency of the product.

[0004] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0005] A dual-head asynchronous cyclic clamping and releasing device includes a top head, a front clamp, a main body, a rear clamp, and a base head. Both the front clamp and the rear clamp are provided with locking components. When the top head clamps the front clamp, the base head is released from the rear clamp. When the top head is released from the front clamp, the base head is clamped from the rear clamp.

[0006] The main body comprises a main shell and a rotating spindle from the outside in. One end of the rotating spindle is connected to the front chuck and its locking mechanism, and the other end is connected to the rear chuck and its locking mechanism. Limiting rods are evenly arranged inside the main shell near the rotating spindle. A guide limiting mechanism, a plane bearing, and a compression spring are sequentially arranged on the rotating spindle. One side of the guide limiting mechanism is a guide mechanism, and the other side is a limiting mechanism. The guide mechanism includes guide grooves evenly arranged around the rotating spindle, and the limiting mechanism includes limiting grooves evenly arranged around the rotating spindle. The limiting grooves include a first limiting groove and a second limiting groove. The number of guide grooves is the same as the sum of the number of the first limiting groove and the second limiting groove. The number of the first limiting groove and the second limiting groove are both the same as the number of limiting rods.

[0007] The top head moves forward to cause the locking element to drive the rotating spindle to move forward, thereby moving the guide groove to the limit rod; the top head moves in reverse to cause the compression spring to drive the rotating spindle to move in reverse, thereby moving the first limit groove or the second limit groove to the limit rod.

[0008] Furthermore, the front chuck is provided with a front clamping sleeve on its exterior, and the front clamping sleeve is connected to one end of the main body shell; the rear chuck is provided with a rear clamping sleeve on its exterior, and the rear clamping sleeve is connected to the other end of the main body shell.

[0009] Furthermore, the rotating mandrel is a cylindrical solid, the main body shell is a hollow cylinder surrounding the rotating mandrel, three limiting rods are evenly provided on the main body shell, the number of guide grooves is six, the first limiting groove and the second limiting groove are arranged adjacent to each other, and the number of the first limiting groove and the number of the second limiting groove are three.

[0010] Furthermore, the limiting rod is a cylindrical solid, the guide groove and the first limiting groove have the same shape and are both arc grooves, and the central angle of the arc groove is adapted to the limiting rod; the second limiting groove is a square groove, and the width of the square groove is adapted to the diameter of the limiting rod.

[0011] Furthermore, both the front locking member and the rear locking member are locking screws.

[0012] Furthermore, the height difference between adjacent limiting rods is 8mm.

[0013] A dual-head asynchronous cyclic clamping method includes:

[0014] S1: Connect the base head to the rear clamp via the locking mechanism, while the top head and front clamp are in a loose state;

[0015] S2: The top head moves forward to push the locking part forward, thereby driving the rotating spindle to move forward, so that the guide groove moves to the limit rod, until the bottom of the guide groove moves to the limit rod;

[0016] S3: The top head moves in the opposite direction to cause the compression spring to drive the rotating spindle to move in the opposite direction, so that the first limiting groove moves to the limiting rod. At the same time, it drives the front chuck to perform a clamping action to complete the clamping with the top head, and drives the rear chuck to perform a releasing action to complete the releasing with the base head. The connection between the rotating spindle and the top head and the release with the base head are completed simultaneously.

[0017] S4: Repeat step S2;

[0018] S5: The top head moves in the opposite direction to cause the compression spring to drive the rotating spindle to move in the opposite direction, so that the second limiting groove moves to the limiting rod. At the same time, it drives the front chuck to loosen and release from the top head, and drives the rear chuck to clamp and clamp with the base head. The loosening of the rotating spindle from the top head and the clamping with the base head are completed simultaneously.

[0019] The beneficial effects of this application are as follows: The dual-head asynchronous cyclic clamping and releasing device and method described in this application, through the forward movement of the top head, causes the locking element to drive the rotating spindle to move forward, thereby moving the guide groove to the limit rod; then, through the reverse movement of the top head, causes the compression spring to drive the rotating spindle to move in the reverse direction, thereby moving the first limit groove or the second limit groove to the limit rod. Through the forward and reverse movements of the top head, the guide groove and limit groove on the rotating spindle can move to the limit rod, thereby achieving synchronous clamping and releasing of the top head and the base head.

[0020] By adding the dual-head asynchronous cyclic clamping and releasing device described in this application to the base of the machine tool, the dual-head asynchronous cyclic clamping and releasing device can move back and forth and up and down with the turret when clamping and releasing are triggered. The dual-head asynchronous cyclic clamping and releasing device can achieve fixed-point following and release, and complete actions such as blowing and rinsing. While reducing costs, it avoids the time waste caused by clamping and separating at different positions in the traditional production process, thereby improving the processing efficiency of the product.

Detailed Implementation

[0027] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 5As shown, the dual-head asynchronous cyclic clamping and releasing device of this application includes a top head 1, a front clamp 2, a main body, a rear clamp 12, and a base head 6. Both the front clamp 2 and the rear clamp 12 are equipped with locking elements 7. When the top head 1 clamps the front clamp 2, the base head 6 releases the rear clamp 12; when the top head 1 releases the front clamp 2, the base head 6 clamps the rear clamp 12.

[0029] The main body is provided with a main body shell 3 and a rotating spindle 9 from the outside to the inside. One end of the rotating spindle 9 is connected to the front chuck 2 and its locking component, and the other end is connected to the rear chuck 12 and its locking component.

[0030] In a specific embodiment, the front clamp 2 is provided with a front clamping sleeve 8, which is connected to one end of the main body shell 3; the rear clamp 12 is provided with a rear clamping sleeve 5, which is connected to the other end of the main body shell 3.

[0031] The main body shell 3 is provided with limiting rods 4 evenly arranged near the rotating spindle 9. The rotating spindle 9 is provided with a guide limiting mechanism, a plane bearing 10 and a compression spring 11 in sequence. One side of the guide limiting mechanism is a guide mechanism and the other side is a limiting mechanism. The guide mechanism includes guide grooves 15 evenly arranged around the rotating spindle 9. The limiting mechanism includes limiting grooves evenly arranged around the rotating spindle 9. The limiting grooves include a first limiting groove 13 and a second limiting groove 14. The number of guide grooves 15 is the same as the sum of the number of the first limiting grooves 13 and the second limiting grooves 14. The number of the first limiting grooves 13 and the second limiting grooves 14 is the same as the number of limiting rods 4.

[0032] Specifically, the guide groove and the limiting groove are arranged opposite to each other and staggered. The two ends of one guide groove correspond to the two limiting grooves respectively, and the two ends of one limiting groove also correspond to the two guide grooves respectively.

[0033] In a specific embodiment of this application, the rotating mandrel 9 is a cylindrical solid, the main body shell 3 is a hollow cylinder surrounding the rotating mandrel 9, three limiting rods 4 are evenly provided on the main body shell 3, the number of guide grooves 15 is six, the first limiting groove 13 and the second limiting groove 14 are arranged adjacent to each other, and the number of the first limiting groove 13 and the second limiting groove 14 is three.

[0034] In a specific embodiment, the limiting rod 4 is a cylindrical solid, the guide groove 15 and the first limiting groove 13 have the same shape and are both arc grooves, and the central angle of the arc groove is adapted to the limiting rod 4; the second limiting groove 14 is a square groove, and the width of the square groove is adapted to the diameter of the limiting rod 4.

[0035] Specifically, the setting of the limiting rod, limiting groove and guide groove is not limited to the above-mentioned shape and quantity. Under the premise that the shape and quantity of the limiting rod, limiting groove and guide groove are compatible, their shape and quantity are not limited.

[0036] Furthermore, the height difference between adjacent limiting rods is 8mm; the height difference between adjacent limiting grooves and adjacent guide grooves is 4mm.

[0037] In a specific embodiment, both the front locking member and the rear locking member are locking screws.

[0038] The working principle of the dual-head asynchronous cyclic clamping and releasing device is as follows: the top head 1 moves forward to cause the locking element 7 to drive the rotating spindle 9 to move forward, thereby moving the guide groove 15 to the limit rod 4; the top head 1 moves backward to cause the compression spring 11 to drive the rotating spindle 9 to move backward, thereby moving the first limit groove 13 or the second limit groove 14 to the limit rod 4; through the forward and reverse movements of the top head 1, the guide groove and limit groove on the rotating spindle 9 move to the limit rod 4, and finally realize the synchronous clamping and releasing of the top head 1 and the base head 6.

[0039] The dual-head asynchronous cyclic clamping method described in this application specifically includes:

[0040] S1: Connect the base head to the rear clamp via the locking mechanism, while the top head and front clamp are in a loose state.

[0041] S2: The top head moves forward to hold the locking part in place, thereby driving the rotating spindle to move forward, causing the guide groove to gradually move to the limit rod. The top head continues to press down, causing the rotating spindle to continue to move forward until the bottom of the guide groove moves to the limit rod.

[0042] S3: The top head moves in the opposite direction to cause the compression spring to drive the rotating spindle to move in the opposite direction, so that the first limiting groove moves to the limiting rod. At the same time, it drives the front chuck to perform a clamping action to complete the clamping with the top head, and drives the rear chuck to perform a releasing action to complete the releasing with the base head. The connection between the rotating spindle and the top head and the release with the base head are completed simultaneously.

[0043] When the rotating spindle is moving in the forward or reverse direction, the entire guide and limit mechanism is in motion, and the guide groove and the limit groove move in the same direction.

[0044] S4: Repeat step S2.

[0045] S5: The top head moves in the opposite direction to cause the compression spring to drive the rotating spindle to move in the opposite direction, so that the second limiting groove moves to the limiting rod. At the same time, it drives the front chuck to loosen and release from the top head, and drives the rear chuck to clamp and clamp with the base head. The loosening of the rotating spindle from the top head and the clamping with the base head are completed simultaneously.

[0046] Because there is a height difference between the first and second limiting grooves on the rotating spindle, the first or second limiting groove can be guided close to the limiting rod by the guide groove, so that the top head and the base head can perform reciprocating clamping and releasing actions.

[0047] Both the front and rear chucks are elastic. When the first limiting groove on the rotating spindle moves to the limiting rod, the front chuck tightens to clamp the top head, while the rear chuck releases the base head. At this time, the rotating spindle is fully locked with the locking mechanism of the front chuck, but not with the locking mechanism of the rear chuck (still in a connected state). When the second limiting groove on the rotating spindle moves to the limiting rod, the front chuck releases the top head, while the rear chuck clamps the base head. At this time, the rotating spindle is not locked with the locking mechanism of the front chuck (still in a connected state), but fully locked with the locking mechanism of the rear chuck.

[0048] The above are exemplary embodiments of this application, and the scope of protection of this application is defined by the claims and their equivalents.
