[0026] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 6 As shown, a workpiece positioning tool provided in this embodiment includes a fixed base 10, a rotating base 20 and a tool fixture; a vertically arranged hollow fixed shaft 11 is provided on the fixed base 10, and a lifting rod 12 that can be lifted and lowered is sleeved in the hollow fixed shaft 11. Specifically, a guide sleeve 13 is sleeved in the hollow fixed shaft 11, and the lift rod 12 is set with a gap between the inner wall of the hollow fixed shaft 11 and is sleeved in the guide sleeve 13 to guide the vertical lifting movement of the lift rod 12 and reduce friction and wear. Of course, in other embodiments, the structure of the lift rod 12 that can be lifted and lowered and sleeved in the hollow fixed shaft 11 is not limited to this.

[0029] The rotating base 20 is rotatably sleeved on the outer side of the hollow fixed shaft 11. Specifically, in this embodiment, a bearing 51 is sleeved on the outer side of the hollow fixed shaft 11. The rotating base 20 includes a rotating shaft 52 with a flange, and is fixed to the outer ring of the bearing 51 through the rotating shaft 52 with a flange, thereby realizing the rotatable assembly of the rotating base 20. Of course, in other embodiments, the rotatable assembly connection structure of the rotating base 20 is not limited to this.

[0030] A rotation drive device 41 and a lifting drive device 42 are fixed on the fixed base 10. The rotation drive device 41 is connected to the rotating base 20 to drive the rotating base 20 to rotate around the hollow fixed shaft 11. The lifting drive device 42 is connected to the push rod 12 to drive the push rod 12 to move up and down.

[0031] The tooling fixture includes a fixture base body 31, a lifting base 33 and a clamping assembly 32. The fixture base body 31 is detachably fixed on the rotating base 20, and a receiving groove 301 for placing a workpiece is provided at the upper end thereof. The lifting base 33 is arranged on the fixture base body 31 and can be lifted and lowered. Specifically, a vertically arranged longitudinal guide rod 312 is provided on the fixture base body 31, and the lifting base is provided with a longitudinal guide hole (not shown), and is sleeved on the longitudinal guide rod 312 to realize lifting and lowering movement.

[0032] The clamping assembly 32 includes a connecting rod 321, a hinge 322 and a product positioning block 323. The hinge 322 is hinged on the fixture base 31, and the product positioning block 323 is fixed on the hinge 322 and extends toward the accommodating groove 301. The two ends of the connecting rod 321 are respectively hinged on the hinge 322 and the lifting seat 33; the lifting drive device 42 drives the lifting movement of the push rod 12 to make the push rod 12 touch the lifting seat 33 and drive the lifting seat 33 to move upward. The upward movement of the lifting seat 33 drives the hinge 322 to swing toward the accommodating groove 301, thereby driving the product positioning block 323 to press against the workpiece 1 placed in the accommodating groove 301.

[0033] When positioning the workpiece 1, place the workpiece 1 in the receiving groove 301 of the fixture, and then drive the lifting drive device 42 to operate, so that the lifting drive device 42 drives the push rod 12 to rise and touch the lifting seat 33. The continued rise of the push rod 12 drives the lifting seat 33 to move up synchronously. The upward movement of the lifting seat 33 drives the hinge 322 to swing toward the receiving groove 301 through the connecting rod 321, and then drives the product positioning block 323 to press on the workpiece 1 placed in the receiving groove 301 to position the workpiece. When processing the workpiece 1, the rotating base 20 can be directly driven by the rotating drive device 41 to rotate around the hollow fixed shaft 11. When the workpiece needs to be removed, the lifting drive device 42 is controlled to drive the push rod 12 to move downward, so that the push rod 12 is separated from the lifting seat 33, and the clamping assembly 32 can release the pressure positioning of the workpiece 1.

[0034] The tooling is configured to be a fixed base 10, a rotating base 20 and a tooling fixture. The fixed base 10 is used to install a rotating drive device 41 and a lifting drive device 42, and its circuit layout will not cause entanglement by following the movements of the rotating base 20 and the tooling fixture. The tooling fixture is used as a positioning part for the workpiece 1, and is detachably connected to the rotating base 20, so that when different types of workpieces 1 need to be switched, it is only necessary to replace the tooling fixture. The fixed base 10 and the rotating base 20 are common parts with good versatility and effectively control the tooling cost. There is no circuit connection between the rotating base 20 and the tooling fixture, and the movement of the clamping assembly 32 is also driven by top contact. The connection structure is well simplified, and 360° arbitrary rotation can be realized, and the assembly and disassembly operations are easier.

[0035] Further preferably, in order to position the workpiece 1 more firmly, in this embodiment, the clamping assembly 32 is provided with two groups, and is symmetrically arranged on both sides of the fixture base 31, and the connecting rods 321 of the two groups of clamping assemblies 32 are hinged on the same lifting seat 33, and the two groups of clamping assemblies 32 are synchronously driven by the lifting seat 33 to press against both sides of the upper surface of the workpiece 1, such as Figure 4 Of course, in other embodiments, the number of the clamping assemblies 32 is not limited thereto, and one or more than two groups may also be used.

[0036] Further preferably, in order to more conveniently arrange the connection structure of the lifting seat 33 and the clamping assembly 32, in this embodiment, the hinge 322 is in a "<" shape, the first end of the hinge 322 is hinged to the clamp seat 31, the middle position of which is toward the receiving groove 301, and the second end thereof extends outward, the product positioning block 323 is fixed to the middle position of the hinge 322, the connecting rod 321 is hinged to the second end of the hinge 322, that is, the connecting rod 321 is located on the outside of the hinge 322, and the movement of the connecting rod 321 does not affect other components, so that the movement range of the clamping assembly 32 is not affected, which is more conducive to the operation. Of course, in other embodiments, the layout structure of the lifting seat 33 and the clamping assembly 32 is not limited to this.

[0037] Further preferably, in order to better assemble and better improve the assembly accuracy of the workpiece 1, in this embodiment, the clamp seat body 31 is provided with a lateral notch (not shown) connected to the accommodating groove 301, and the clamp seat body 31 is provided with a movable block 311 that can move translationally to approach or move away from the lateral notch; it also includes a first elastic member (not shown), the first elastic member applies an inward elastic force to the movable block 311 to drive the movable block 311 to move inwardly to approach the lateral notch; the movable block 311 is connected to the hinge 322, which is connected in this specific embodiment. Figure 4 The hinge 322 of the left clamping assembly 32 in the embodiment drives the movable block 311 to translate outward to move away from the lateral notch by swinging the hinge 322 outward. When the workpiece 1 needs to be placed or removed, the hinge 322 is driven to swing outward under the action of an external force, and an outward pulling force is applied to the movable block 311. The movable block 311 overcomes the action of the first elastic member and is synchronously taken away. At this time, the workpiece can be placed or removed; when the workpiece 1 is pressed and positioned, the hinge 322 swings inward under the action of the upward movement of the lifting seat 33, and then the pulling force on the movable block 311 is lost. The movable block 311 moves inward again (i.e., close to the lateral notch) under the action of the first elastic member and presses against the side of the workpiece 1 exposed in the lateral notch, and further positions the workpiece 1 in the horizontal direction, which is not easy to loosen. In this embodiment, the elastic force of the first elastic member is used to drive the movable block 311 to press against the side of the workpiece 1, which can reduce the pressure damage to the workpiece 1.

[0038] To be more specific, in this embodiment, a horizontal guide rod (not shown) is fixed to the clamp base body 31, a horizontal guide hole (not shown) is opened on the movable block 311, and the movable block 311 is sleeved on the horizontal guide rod through the horizontal guide hole; the first elastic member is a lateral return spring, and the lateral return spring is sleeved on the horizontal guide rod, and the horizontal guide rod has an abutment end cap (not shown), one end of the lateral return spring abuts on the abutment end cap, and the other end abuts on the movable block, which has the characteristics of simple structure and compact assembly.

[0039] Further preferably, in this embodiment, a second elastic member 34 is further provided between the clamp seat body 31 and the lifting seat 33, and the second elastic member 34 applies a downward elastic force to the lifting seat 33. Through the elastic force of the second elastic member 34, when the lifting seat 33 loses the top contact force of the top rod 12, the lifting seat 33 can move down quickly and timely under the action of its own gravity and the elastic force of the second elastic member 34, thereby driving the clamping assembly 32 to release the workpiece 1 without manual prying. Specifically, the second elastic member 34 is a longitudinal return spring, and there are two of them, which are distributed on the left and right sides, and the force is more uniform. Of course, in other embodiments, if the self-gravity of the lifting seat 33 can meet the automatic downward movement, the structure of the second elastic member 34 may not be required.

[0040] Further preferably, in this embodiment, the lifting seat 33 includes a force-bearing top block 331, an angular contact bearing 332 and a connecting frame 333, wherein the force-bearing top block 331 is fixedly connected to the inner ring of the angular contact bearing 332, and the connecting frame 333 is fixedly connected to the outer ring of the angular contact bearing 332, and the force-bearing top block 331 corresponds to the top rod 12 and is used to contact the top rod 12, that is, the top rod 12 contacts the force-bearing top block 331. The connecting frame 333 can rotate relative to the force-bearing top block 331, and the connecting frame 333 is hinged to the connecting rod 321 of the clamping assembly 32. In this way, the angular contact bearing 332 is used to realize that the rotation and the up and down movement are not affected by each other. Of course, in other embodiments, the rotation driving force of the rotating base 20 is large enough to ignore the friction between the lifting seat 33 and the top rod 12 for normal rotation, and the lifting seat 33 can also be set as a whole, but a certain degree of wear will be caused between the lifting seat 33 and the top rod 12, which is not a preferred solution.

[0041] Further preferably, in the present embodiment, the specific way in which the clamp seat body 31 is detachably fixed to the rotating base 20 is as follows: a slot 21 is provided on the rotating base 20, and a positioning pin 22 and a retractable elastic buckle 23 are respectively provided at both ends of the slot 21; the clamp seat body 31 is slidably clamped in the slot 21, and the two ends in the sliding direction are respectively restricted by the positioning pin 22 and the elastic buckle 23 extending out of the rotating base 20. When disassembly is required, the elastic buckle 23 is pressed to make the elastic buckle 23 move downward and retract into the rotating base 20 to make way, at which time the jig can be moved out of the slot 21 as a whole; similarly, when the jig is to be assembled, the bottom surface of the jig is pressed on the elastic buckle 23 to make the elastic buckle 23 retract and make way, the jig is aligned with the slot 21 and slidably engaged into the slot 21, when the jig is moved into place, it is out of the position of the elastic buckle 23, and the elastic buckle 23 automatically pops out to restrict the end of the jig seat 31. It has a simple structure and is easy and fast to assemble and disassemble.

[0042] Furthermore, in this embodiment, the clamp seat 31 is provided with a first inclined mating surface (not shown) at one end corresponding to the elastic buckle 23, and the elastic buckle 23 is provided with a second inclined mating surface (not shown) that is obliquely matched with the first inclined mating surface. The elastic buckle 23 can exert a thrust on the clamp seat 31 toward the positioning pin 22 through the cooperation of the first inclined mating surface and the second inclined mating surface. When the elastic buckle is automatically popped out, the second inclined mating surface of the elastic buckle 23 contacts the first inclined mating surface of the clamp seat 31, as shown in FIG. Figure 8 As shown in the matching structure 25 in which the second inclined matching surface abuts against the first inclined matching surface, the elastic buckle 23 continues to pop up and move upward, and relative sliding occurs between the first inclined matching surface and the second inclined matching surface, thereby pushing the fixture seat 31 to continue to move toward the positioning pin 22 until it is in place. The matching structure of the first inclined matching surface and the second inclined matching surface can ensure a higher assembly accuracy of the fixture. At the same time, the operator can observe the matching of the first inclined matching surface and the second inclined matching surface to quickly and accurately determine whether the fixture is assembled in place.

[0043] Of course, in other embodiments, the fixture base 31 and the rotating base 20 may also be assembled using other detachable connection structures.

[0044] Specifically, in this embodiment, the rotating drive device 41 is a rotating motor, a driving wheel 411 is sleeved on the rotating shaft of the rotating motor, a driven wheel 24 is provided on the rotating base 20, and a conveyor belt 412 is also included, the conveyor belt 412 is sleeved on the driving wheel 411 and the driven wheel 24, so as to realize the transmission link between the rotating motor and the rotating base 20. More specifically, the lifting drive device 42 is a driving cylinder, the driving cylinder is located below the hollow fixed shaft 11, and its piston rod is fixedly connected to the push rod 12 through a floating joint, and the extension and contraction of the piston rod of the driving cylinder drives the push rod 12 to rise and fall. The arrangement of the rotating drive device 41 and the lifting drive device 42 is simple in structure and easy to realize.

[0045] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
