DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0058] See also Figure 1-Figure 10 The embodiment of the present invention provides a multi-angle clamping processing fixture, comprising a clamping bracket 1, on which a detection control support plate 2 is fixedly mounted, and further comprising:

[0059] A rotating adjustment shaft 5, wherein the rotating adjustment shaft 5 is rotatably connected to the clamping bracket 1, and a clamping adjustment support 6 is fixedly mounted on the other end of the rotating adjustment shaft 5;

[0060] and a multi-angle clamping mechanism, the multi-angle clamping mechanism is respectively connected to the detection control support plate 2, the rotation adjustment shaft 5 and the clamping adjustment support 6, wherein the multi-angle clamping mechanism includes a circumferential clamping adjustment component and a rotation adjustment component;

[0061] The circumferential clamping adjustment component is connected to the clamping adjustment support 6, and the rotation adjustment component is respectively connected to the detection control support plate 2 and the rotation adjustment shaft 5, and is electrically connected to the circumferential clamping adjustment component.

[0062] See also Figure 1-Figure 10 , further comprising: a stopper 7, wherein the stopper 7 is fixedly mounted on the rotation adjustment shaft 5;

[0063] And a positioning brake assembly, wherein the positioning brake assembly is connected to the detection control support plate 2 and is detachably connected to the stopper 7.

[0064] The positioning brake assembly comprises:

[0065] A brake support 4, wherein the brake support 4 is fixedly mounted on the detection and control support plate 2;

[0066] And a positioning telescopic cylinder 3, which is fixedly connected to the brake support 4, and an arc-shaped pushing portion 8 is fixedly installed on the output end of the positioning telescopic cylinder 3, and the arc-shaped pushing portion 8 is slidably connected to the brake support 4 and detachably connected to the stop portion 7.

[0067] During the machining process, first, the clamping bracket 1 can be fixed to the machine tool or other equipment by bolt connection, and then, according to the structure and other characteristics of the workpiece, the rotating adjustment shaft 5 is driven to rotate on the clamping bracket 1, wherein the driving mode of the rotating adjustment shaft 5 can be human-driven or mechanically (such as a motor). No further details will be given here. As the rotating adjustment shaft 5 rotates, the clamping adjustment support 6 can be driven to rotate synchronously, so that the circumferential clamping adjustment component on the clamping adjustment support 6 can form a certain angle with the horizontal plane. At the same time, during the rotation of the rotating adjustment shaft 5, the rotating adjustment component will also be driven to move. On the one hand, the rotating adjustment component can detect the rotation angle of the clamping adjustment support 6, thereby accurately controlling the angle between the circumferential clamping adjustment component and the horizontal plane, so that the rotation angle of the clamping adjustment support 6 and the circumferential clamping adjustment component is adapted to the workpiece to be processed. On the other hand, as the rotation angle of the clamping adjustment support 6 and the circumferential clamping adjustment component changes, for example, the smaller the angle formed by the circumferential clamping adjustment component and the horizontal plane (that is, when it is close to the horizontal position, such as Figure 1As shown, at this time, under the action of the workpiece's own gravity, the clamping effect will be affected, and displacement or vibration may occur during the processing, and the closer to the horizontal position, the greater the possibility of displacement or vibration). The rotary adjustment component will also increase the clamping force of the circumferential clamping adjustment component on the workpiece accordingly, and as the angle gradually changes, the clamping force also gradually changes, thereby saving energy while ensuring the clamping effect in different position states, thereby improving the practicality and flexibility of the equipment. For details, please refer to the following content. After the angle adjustment between the circumferential clamping adjustment component and the horizontal plane is completed, the arc-shaped pushing portion 8 can be pushed to move in the direction of the stop portion 7 through the positioning telescopic cylinder 3 set, and squeezed on the stop portion 7, wherein the stop portion 7 It can be in the form of a gear, and the arc-shaped pushing portion 8 correspondingly adopts the form of an arc-shaped toothed plate, so that a braking effect can be formed on the rotating adjustment shaft 5. Of course, the stop portion 7 and the arc-shaped pushing portion 8 can also adopt other forms, which will not be elaborated here. Then, the staff will immediately adjust the circumferential clamping adjustment component to make a certain position on the circumference of the clamping adjustment support 6 provide a clamping force to the workpiece (according to the structure of the workpiece, etc., start the circumferential clamping adjustment component at the corresponding position). The operation is simple, and the purpose of multi-angle adjustment can be achieved according to the clamping requirements of the workpiece, thereby improving the practicability and flexibility of the equipment, and while saving energy, it can ensure the clamping effect of the workpiece in different position states, providing convenience for the staff.

[0068] In one embodiment of the present invention, see Figure 1-Figure 10 , the circumferential clamping adjustment assembly comprises:

[0069] A clamping control seat 9, wherein the clamping control seat 9 is fixedly mounted on the clamping adjustment support 6, and a plurality of bases 23 are evenly mounted on the clamping control seat 9, and a reset control cylinder 12 is fixedly mounted on each of the bases 23;

[0070] A clamping telescopic rod 17, wherein the clamping telescopic rod 17 passes through the reset control cylinder 12 and is slidably connected to the reset control cylinder 12, wherein a spring is provided in the reset control cylinder 12, and two ends of the spring are fixedly connected to the reset control cylinder 12 and the clamping telescopic rod 17 respectively;

[0071] A clamping jaw 18, wherein the clamping jaw 18 is fixedly connected to one end of the clamping telescopic rod 17, and a plurality of the clamping jaws 18 surround a workpiece placement portion 22, and the workpiece placement portion 22 is located in the middle of the clamping control seat 9;

[0072] And a circumferential adjustment driving unit, the circumferential adjustment driving unit is connected to the clamping adjustment support 6, and is detachably connected to the clamping telescopic rod 17, and the circumferential adjustment driving unit is also electrically connected to the rotation adjustment component.

[0073] The circumferential adjustment driving unit comprises:

[0074] An annular control groove 10, the annular control groove 10 is opened on the clamping adjustment support 6, and two stop sliders 37 are slidably installed in the annular control groove 10, and a sliding support rod 24 is fixedly installed on each of the stop sliders 37, and the two sliding support rods 24 are connected by a linkage connecting rod 14;

[0075] A positioner 25, the positioner 25 is fixedly mounted on the sliding support rod 24 and is slidably connected to the clamping and adjusting support 6, and the positioner 25 is also electrically connected to the stop slider 37;

[0076] and a driving module, wherein the driving module is fixedly connected to the sliding support rod 24 and electrically connected to the rotation adjustment component.

[0077] The driving module comprises:

[0078] An adjusting drive chamber 19, wherein the adjusting drive chamber 19 is fixedly mounted on the sliding support rod 24;

[0079] A clamping drive member 20, wherein the clamping drive member 20 is slidably mounted in the adjusting drive compartment 19, and an output end of the clamping drive member 20 is detachably connected to the clamping telescopic rod 17;

[0080] And a clamping compensation device 26, which is fixedly installed in the adjustment drive bin 19 and is located between the adjustment drive bin 19 and the clamping drive member 20, and the clamping compensation device 26 is also electrically connected to the rotation adjustment component.

[0081] See also Figure 1-Figure 10 , further comprising: a pointer 16, wherein the pointer 16 is fixedly mounted on the linkage link 14;

[0082] And a scale indicating surface 15, wherein the scale indicating surface 15 is located on the top of the clamping and adjusting support 6 and is slidably connected to the pointer 16.

[0083] It also includes: a limit baffle 11, the number of the limit baffle 11 is multiple, and the multiple limit baffles 11 are evenly fixed on the clamping control seat 9;

[0084] A connecting plate 21, wherein the connecting plate 21 is fixedly mounted on the end of the clamping telescopic rod 17 and is slidably connected to the limit baffle 11;

[0085] And a second connecting plate 27, wherein the second connecting plate 27 is fixedly connected to the output end of the clamping driving member 20 and is detachably connected to the first connecting plate 21.

[0086] When clamping the workpiece at the workpiece placement portion 22 at a certain position in the circumferential direction of the clamping and adjusting support 6, first, the linkage connecting rod 14 is rotated by manpower to drive the two sliding support rods 24 to rotate synchronously, wherein the two sliding support rods 24 are symmetrically installed on the linkage connecting rod 14, and during the rotation of the sliding support rod 24, the stop slider 37 can be driven to rotate in the annular control groove 10, and then, according to the pointer 16 rotating to the required position on the scale indicating surface 15, the adjustment drive bin 19 and the clamping drive member 20 can be rotated to the specified position. At this time, under the control of the positioner 25, the stop slider 37 can be started, wherein the positioner 25 can be in the form of a sensor, and the corresponding parameters are set on the control panel (not shown in the figure). After that, when the linkage link 14 rotates to the specified angle, the positioner 25 is started, so that the stop slider 37 can be actuated, and the stop slider 37 can be in the form of an electromagnet. After the stop slider 37 is started, the stop slider 37 can be adsorbed on the specified position in the annular control groove 10, thereby realizing the positioning of the adjustment drive bin 19 and the clamping drive member 20, which is beneficial to further improve the accuracy of the angle adjustment of the adjustment drive bin 19 and the clamping drive member 20. At this time, starting the clamping drive member 20 can push the connecting plate 27 to move toward the center direction of the clamping control seat 9 and contact with the connecting plate 1 21, so that the clamping telescopic rod 17 can be pushed to slide in the reset control cylinder 12, and the spring is in a compressed state, and the clamping telescopic rod 17 will push the clamping claw 18 The workpiece is clamped (at least one pair of symmetrically arranged clamping jaws 18 is used to clamp the workpiece each time), wherein the clamping jaws 18 on the multiple clamping telescopic rods 17 can adopt a unified structure, or can be set with different specifications and structures according to the different positions of the workpiece to achieve a better clamping effect. For example, when the clamping adjustment support 6 is in a vertical state, when a pair of clamping jaws 18 in a horizontal state are performing a clamping operation, the workpiece may also be displaced or vibrated under the action of its own gravity. At this time, the pair of clamping jaws 18 can achieve better clamping by optimizing their own shape and material, for example, using a material with a higher friction coefficient to make the clamping jaws 18 or designing the clamping jaws 18 to be able to adapt to workpieces of different shapes. The clamping jaws 18 are designed to have a certain effect, and the other pairs of clamping jaws 18 can be designed according to the clamping situation, which will not be described in detail here. Of course, the clamping jaw structure can also be directly set on the output end of the clamping drive member 20 according to the production cost and other conditions. When the adjusting drive bin 19 and the clamping drive member 20 rotate, the clamping jaw structure is directly driven to rotate. At this time, there is no need to set the reset control cylinder 12, the clamping telescopic rod 17 and the clamping jaw 18 and other structures, which can be selected according to the actual situation. In addition, after the clamping drive member 20 pushes the connecting plate 27 to contact the connecting plate 1 21, the two slide in the limit baffle 11, which can play a certain limiting role on the adjusting drive bin 19 and the clamping drive member 20, so as to avoid the clamping drive member 20 pushing the clamping jaw 18 to clamp.The sliding support rod 24 and the stop slider 37 rotate in the annular control groove 10, thereby further ensuring the smooth progress of the clamping operation. In addition, when the rotating adjustment component is actuated, the clamping compensation device 26 will start working, wherein the clamping compensation device 26 can also be in the form of an electromagnet, and according to the angle change between the clamping adjustment support 6 and the horizontal plane, the clamping compensation device 26 generates a magnetic repulsion effect on the clamping drive member 20 with different magnetic repulsion forces, thereby changing the clamping force of the clamping jaw 18 on the workpiece, wherein the clamping drive member 20 is slidably connected to the adjustment drive bin 19, and a conventional slide groove and guide rail matching structure can be adopted, and in the normal clamping working state, the clamping drive member 20 The end of the clamping compensation device 26 just contacts the clamping compensation device 26. At this time, the clamping drive member 20 can no longer slide in the direction of the clamping compensation device 26 through the design of the slide slot length. After the clamping compensation device 26 is started, the clamping drive member 20 can be pushed to slide a short distance away from the clamping drive member 20 (the sliding distance is very small, and the sliding distance varies depending on the size of the electromagnetic force). On the one hand, the clamping force of the clamping claw 18 can be increased, and on the other hand, it can play a certain buffering role, so that the clamping force gradually changes with the gradual change of the angle, which can save energy while ensuring the clamping effect in different position states, thereby improving the practicality and flexibility of the equipment.

[0087] In one embodiment of the present invention, see Figure 1-Figure 10 , the rotation adjustment component comprises:

[0088] A winding drum 28, wherein the winding drum 28 is fixedly connected to the detection and control support plate 2, and the winding drum 28 is also sleeved on the rotation adjustment shaft 5 and is rotationally connected to the rotation adjustment shaft 5;

[0089] A pull belt 29, one end of which is wound around the rotating adjustment shaft 5, and the other end of which passes through the winding drum 28 and is slidably connected to the winding drum 28;

[0090] And a mobile detection unit, which is respectively connected to the detection control support plate 2 and the pull belt 29, and is electrically connected to the circumferential clamping adjustment component.

[0091] The mobile detection unit comprises:

[0092] A mobile recording device 30, wherein the mobile recording device 30 is fixedly mounted on the detection control support plate 2 and is electrically connected to the circumferential clamping adjustment assembly, and a limited sliding groove 31 and a communication port 32 are also provided on the mobile recording device 30;

[0093] A mobile controller 33, which is inserted into the communication port 32 and fixedly connected to the drawstring 29, and is also slidably mounted in the limiting slide groove 31;

[0094] The mobile recording device 30 is also provided with a tension spring, and the two ends of the tension spring are respectively fixedly connected to the mobile recording device 30 and the mobile controller 33;

[0095] Pointer 2 35, the pointer 2 35 is fixedly connected to the mobile controller 33;

[0096] And a second scale indicating surface 34 , wherein the second scale indicating surface 34 is located on the top of the mobile recording device 30 and is slidably connected to the second pointer 35 .

[0097] When adjusting the angle between the clamping adjustment support 6 and the horizontal plane, during the rotation of the rotating adjustment shaft 5, the drawstring 29 will be wound on the rotating adjustment shaft 5, or the drawstring 29 will fall off from the rotating adjustment shaft 5 under the pulling action of the tension spring, and during the winding and loosening of the drawstring 29, the mobile controller 33 will slide in the limiting slide groove 31. For example, when the clamping adjustment support 6 is rotated from a vertical state to a horizontal state, the rotating adjustment shaft 5 will wind up the drawstring 29, and the drawstring 29 will pull the mobile controller 33 to slide in the connecting port 32 and the limiting slide groove 31, and make the mobile controller 33 gradually approach the winding drum 28. In this process, the position of the pointer 2 35 moving on the scale indication surface 2 34 is The rotation angle of the clamping and adjusting support 6 can be indirectly determined, thereby ensuring the accuracy of the angle adjustment of the clamping and adjusting support 6. In addition, during the sliding process of the mobile controller 33, the mobile recording device 30 can also be activated, wherein a structure similar to a sliding rheostat can be arranged in the mobile recording device 30. During the movement of the mobile controller 33, the magnitude of the current passed into the clamping compensation device 26 can be changed, thereby achieving that as the angle of the clamping and adjusting support 6 changes, the clamping force also gradually changes, so as to avoid the workpiece from moving or vibrating under the action of its own gravity during the processing. In addition, a display device 36 is also arranged on the mobile recording device 30 to observe the on-off status of the overall circuit, which will not be elaborated here.
