[0036] The present invention is described in further detail below with reference to the accompanying drawings.

[0037] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0038] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0039] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0040] For example 1, please refer to Figures 1-6A multifunctional tool fixture includes a base frame 1 and a top plate 2. The top plate 2 is arranged above the base frame 1, and the central axis of the top plate 2 is arranged collinearly with the central axis of the base frame 1. A rubber base 13 is fixed to one side of the base frame 1. The rubber base 13 arranged at the bottom of the base frame 1 can not only improve the stability of the device during use, but also have an anti-slip effect. The projected area value of the base frame 1 is larger than the projected area value of the top plate 2. A lifting member 3 adapted to the top plate 2 is provided on one side of the base frame 1, and the lifting member 3 is used to adjust the height position of the top plate 2.

[0041] A positioning member 4 is provided on one side of the top plate 2 and is used to position the workpiece. A clamping member 5 is provided on one side of the top plate 2 and is used to assist in longitudinal clamping and positioning of the workpiece.

[0042] In this solution, when the overall height position of the top plate 2 needs to be adjusted, the lifting member 3 is driven to enable the top plate 2 to be stably and uniformly adjusted in height position after being subjected to force, thereby meeting the use requirements at different heights. The positioning member 4 and the clamping member 5 are arranged in coordination to position the workpiece longitudinally and transversely respectively.

[0043] Further, such as Figure 1 、 Figure 3 and Figure 4 The lifting member 3 is shown in FIG3 , which includes a cylinder 31 , which is fixed to one side of the base frame 1 , and an output end of the cylinder 31 is fixed to one side of the top plate 2 through a pad 32 , the size of the pad 32 is larger than the size of the output end of the cylinder 31 , and the shape of the pad 32 is circular, so as to better disperse the lifting force of the cylinder 31 , thereby greatly improving the stability and smoothness of the lifting of the top plate 2 , and a guide rod 33 is fixed to the top surface of the base frame 1 , the optimal number of guide rods 33 is four, and the guide rods 33 are located at the four corners of the top plate 2 , and a limiting ring 12 is fixed to the end of the guide rod 33 away from the base frame 1 , and the diameter of the limiting ring 12 is larger than the diameter of the guide rod 33 , through the setting of the limiting ring 12 , it plays a limiting role on the guide rod 33 , which can prevent the top plate 2 from detaching from the guide rod 33 due to excessive lifting distance. The top plate 2 and the guide rod 33 are slidably penetrated, and the setting of multiple guide rods 33 effectively plays a guiding role when the top plate 2 is lifted or lowered.

[0044] It should be noted that, by utilizing the drive of the cylinder 31, a lifting force is applied to the pad 32 in advance, so that the top plate 2 is driven to move up and down smoothly after being subjected to the force. This not only prevents the top plate 2 from shaking when it is lifted or lowered, but also ensures that the top plate 2 is lifted or lowered in a relatively stable state. In conjunction with the sliding setting of the top plate 2 and the guide rod 33, it plays a guiding role when the top plate 2 is lifted or lowered.

[0045] Further, such as Figure 1 、 Figure 2、 Figure 4 and Figure 6 As shown, the positioning member 4 includes: a threaded sleeve 41, the threaded sleeve 41 is fixed to the top surface of the top plate 2, a screw a42 is threadedly connected to the threaded sleeve 41, a rotating wheel a43 is fixed to one end of the screw a42, the central axis of the rotating wheel is collinear with the central axis of the screw a42, and the other end of the screw a42 is rotatably connected to a positioning ring 44, the positioning ring 44 is circular in shape, and one side of the positioning ring 44 is chamfered;

[0046] Rotating rod 45, rotating rod 45 is fixed to the top surface of top plate 2, one side of rotating rod 45 is rotatably connected with positioning plate 46, the angle of positioning plate 46 close to positioning ring 44 is set at a right angle, one side of positioning plate 46 is set at a chamfered inclined surface, a groove 47 is provided on one side of positioning plate 46, a mounting rod 48 is fixed in the groove 47, and a tension spring 49 is jointly connected between the two mounting rods 48, and the tension spring 49 is used to rebound and reset the positioning plate 46.

[0047] It should be noted that the threaded rod a is driven to rotate by rotating the wheel a43, and the threaded transmission between the threaded rod a and the threaded sleeve 41 is used to drive the positioning ring 44 to move, and the positioning ring 44 applies pressure to the workpiece. When the workpiece is placed on the top plate 2, the positioning plate 46 applies pressure to the workpiece, driving the positioning plate 46 to flip over. At this time, the tension spring 49 is in a stretched state.

[0048] Further, such as Figure 1 、 Figure 4 and Figure 6 As shown, the clamping member 5 includes: a bearing seat 51, the bearing seat 51 is fixed to one side of the top plate 2, a bidirectional reciprocating screw 52 rotates in the bearing seat 51, the length of the bidirectional reciprocating screw 52 is greater than the length of the top plate 2, the bidirectional reciprocating screw 52 is externally threaded with a wire sleeve 53, and a slide groove 54 for sliding a connecting plate 55 is provided on one side of the top plate 2, the angle between the connecting plate 55 and the mounting plate 6 is set at a right angle, the opening length of the slide groove 54 is greater than the thread length of the bidirectional reciprocating screw 52, ​​and the setting of the opening length of the slide groove 54 can prevent the wire sleeve 53 from moving too far and causing it to be disconnected from the bidirectional reciprocating screw 52, ​​and a connecting plate 55 is fixed on one side of the wire sleeve 53;

[0049] The clamping plate 56 is arranged on one side of the connecting plate 55, and a rubber pad 14 is fixed on one side of the clamping plate 56. One side of the rubber pad 14 is set with a chamfered inclined surface. The clamping plate 56 slides through the connecting plate 55 through a guide rod 59, and a spring 57 is connected to the outer sleeve of the guide rod 59. By utilizing the elastic effect of the spring 57, when the clamping plate 56 comes into contact with the workpiece, the spring 57 is in a compressed state, thereby playing a pre-tightening role when clamping the workpiece, thereby improving the clamping and positioning effect of the workpiece. The two ends of the spring 57 are respectively fixed to the connecting plate 55 and one side of the clamping plate 56, and a servo motor 58 is fixed to one side of the top plate 2 through a support frame. The clamping plate 56 moves through the precise control of the servo motor 58, so that the clamping force on the workpiece can be precisely adjusted. The output shaft of the servo motor 58 is coaxially fixed with the bidirectional reciprocating screw 52.

[0050] It should be noted that, driven by the servo motor 58, the two clamping plates 56 move synchronously toward the workpiece, achieving a clamping and positioning effect on the transverse surface of the workpiece, and cooperating with the elastic action of the spring 57, thereby achieving a pre-tightening effect, and can also prevent damage to the workpiece due to excessive clamping force, and can meet the clamping requirements of workpieces of different sizes.

[0051] For example 2, please refer to Figure 1 and Figure 2 This embodiment further explains the first embodiment, and the difference lies in that the clamping member 5 is optimized and a component for positioning the top surface of the workpiece is added.

[0052] Specifically, a mounting plate 6 is fixed to the top of the connecting plate 55, and the angle between the mounting plate 6 and the connecting plate 55 is set at a right angle. A sliding sleeve 7 slides on the outside of the mounting plate 6, and a screw b8 is threadedly connected to one side of the sliding sleeve 7. A guide groove 9 for sliding the screw b8 is provided on one side of the mounting plate 6. Both sides of the guide groove 9 are set with smooth arc surfaces, which can prevent the screw b8 from getting stuck when it moves to the dead point position. A runner b10 is fixed to one end of the screw b8, and a pressure ring 11 is rotatably connected to the other end of the screw b8. The pressure ring 11 is circular in shape, and the material of the pressure ring 11 is soft.

[0053] Among them, rotating the wheel b10 drives the threaded rod b to rotate, and the threaded transmission effect between the threaded rod b and the sliding sleeve 7 is used to drive the pressure ring 11 to move downward, so that the pressure ring 11 applies pressure to the top surface of the workpiece, and then the workpieces of different thicknesses can be positioned.

[0054] In this solution, when the workpiece needs to be positioned at an angle, the working principle of the workpiece positioning and clamping is as follows:

[0055] First, place the workpiece on the top surface of the top plate 2. When the height of the top plate 2 and the workpiece needs to be adjusted, the cylinder 31 is driven to make the top plate 2 move upward along the surface of the guide rod 33 after being subjected to force, thereby achieving the purpose of adjusting the height of the top plate 2 and the workpiece.

[0056] Secondly, the workpiece placed on the top plate 2 is pushed toward the positioning plate 46 to ensure that the workpiece is in contact with the positioning plate 46. By rotating the rotating wheel a43, the threaded rod a is rotated synchronously. The threaded transmission effect of the threaded rod a and the threaded sleeve 41 is utilized to cause the threaded rod a to move forward in a spiral after being subjected to force, thereby driving the positioning ring 44 to move synchronously. The positioning ring 44 is in contact with the workpiece, so that the workpiece is forced to move toward the positioning plate 46. The positioning plate 46 is turned over along the axis of the rotating rod 45 after being subjected to force. At this time, the tension spring 49 is in a stretched state, thereby clamping and positioning the workpiece at the positioning plate 46 and the positioning ring 44.

[0057] Then, the servo motor 58 drives the bidirectional reciprocating screw 52 to rotate synchronously. The threaded transmission between the bidirectional reciprocating screw 52 and the wire sleeve 53 causes the wire sleeve 53 to move along the direction in which the slide groove 54 is opened, thereby driving the connecting plate 55 to move synchronously, causing the clamping plate 56 to contact the workpiece, causing the spring 57 to be compressed after being subjected to force, thereby forming a clamping state for the workpiece and completing the lateral positioning state of the workpiece.

[0058] Finally, when the workpiece needs to be further positioned, the sliding sleeve 7 is pushed and adjusted to the appropriate position of the pressure ring 11. The threaded rod b is rotated synchronously by rotating the wheel. The threaded transmission effect between the threaded rod b and the sliding sleeve 7 is used to drive the pressure ring 11 to move synchronously, thereby completing the positioning of the workpiece.

[0059] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
