Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a highly flexible machining fixture. Background Technology

[0002] During material processing, fixtures can accurately determine the position of the workpiece in the machine tool coordinate system and firmly clamp it, preventing displacement due to external forces such as cutting forces and centrifugal forces. However, due to the complexity of the processing technology, there are often multiple surfaces that need to be processed. Existing fixtures cannot adjust the angles and can only adjust the angles of the parts manually, which increases the clamping and adjustment time, thereby reducing production efficiency. Furthermore, when manually reclamping and adjusting the angles of the parts, it is difficult to ensure that the parts return to the precise processing position, which can lead to deviations in subsequent processing accuracy and affect the processing quality. Utility Model Content

[0003] The purpose of this invention is to provide a highly flexible machining fixture to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows:

[0005] This application provides a highly flexible machining fixture, including a base and a fixture device. A support seat is provided on the base, a slide rail is provided on the support seat, a table is movably mounted on the slide rail, and the table has side plates on both sides. The fixture device is located between the two sets of side plates.

[0006] One set of side plates is provided with a sliding flip assembly, which includes a push rod component. The push rod component is located on one side of the side plate, and a slide is installed on the movable end of the push rod component. The slide has a support plate parallel to the side plate, and the support plate has slots.

[0007] The clamping device includes a machine base, on which a gripper plate seat is movably mounted. A connecting shaft is provided on one side of the machine base. One end of the connecting shaft extends to the outside of the side plate and is fitted with a receiving seat. A short shaft is provided on the receiving seat and is fitted into a slot. A support shaft is provided on the other side of the machine base and is movably connected to the side plate.

[0008] When the slide table moves relative to the push rod assembly, the side plate drives the short shaft to move relative to the side plate. During the movement, the receiving seat drives the connecting shaft to rotate, so that the machine table rotates synchronously.

[0009] The movement of the platform on the slide rails drives the relative movement of the machine tool.

[0010] In one embodiment, the clamping device can be configured to have both a vertical and a horizontal state through the cooperation of the push rod component and the slide table.

[0011] When the piston end of the push rod component drives the slide away from the push rod component, the clamping device rotates until the jaw plate seat in the clamping device is parallel to the push rod component, and the clamping device is in a vertical state.

[0012] When the piston end of the push rod component drives the slide table to approach the push rod component, the clamping device rotates until the jaw plate seat in the clamping device is perpendicular to the push rod component, at which point the clamping device is in a lateral state.

[0013] In one embodiment, a rotary drive component is also included. The rotary drive component includes a drive motor, which is mounted on the machine base and located on one side of the gripper plate seat. A drive wheel is keyed to the output end of the drive motor, and a spindle extending into the machine base is connected to the bottom of the gripper plate seat. A driven wheel is mounted on the spindle.

[0014] A synchronous belt connects the driving pulley and the driven pulley;

[0015] With the help of the synchronous belt, when the drive motor drives the driving wheel to rotate, the driven wheel drives the gripper plate to rotate synchronously.

[0016] In one embodiment, the device further includes a cable chain component, with an extension plate provided on the side plate away from the sliding flip assembly, and the chain portion of the cable chain component is connected to the extension plate.

[0017] In one embodiment, contact sensing components are provided on both sides of the interior of the support base, and the two sets of contact sensing components are symmetrically distributed between each other.

[0018] In one embodiment, the base is provided with fixing holes, and several fixing holes are provided and evenly distributed around the base.

[0019] A fixing pin is movably installed on the fixing hole.

[0020] In one embodiment, the gripper plate base has movable jaws, and several movable jaws are provided and evenly distributed along the circumference of the gripper plate base.

[0021] Several movable jaws form a clamping area for holding materials.

[0022] The advantages or beneficial effects of the above technical solutions include at least the following:

[0023] This application discloses a highly flexible processing fixture. By moving a platform located on a slide rail according to the length of the material, the platform moves the fixture device to change its position. The material is then clamped by the gripper plate and processing begins. During processing, when different angles are required to process the material according to different processing techniques, the extension and retraction of the push rod component moves the slide, causing the support plate on the slide to rotate the short shaft of the receiving seat. Since the receiving seat is connected to the machine tool via a connecting shaft, when the receiving seat rotates along the circumference of the short shaft, the connecting shaft causes the machine tool to rotate relative to it, thereby adjusting the angle between the material and the processing equipment. Furthermore, the platform can be moved to adjust the material's position according to actual usage. Through the cooperation of the sliding and flipping components and the fixture device, material adjustment can be achieved during processing, making it suitable for different processing techniques. This solves the problem of accuracy deviations that occur with manual adjustments and improves production efficiency. Attached Figure Description

[0040] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0041] Reference Figures 1-5A highly flexible processing fixture includes a base 1 and a clamping device 2. The clamping device 2 is used to clamp materials. The base 1 is provided with a bearing seat 11, and the bearing seat 11 is provided with a slide rail 111. A platform 112 is movably mounted on the slide rail 111. The platform 112 has side plates 113 on both sides. The clamping device 2 is located between the two sets of side plates 113. The slide rail 111 can guide the movement of the platform 112.

[0042] One of the side plates 113 is provided with a sliding flip assembly 3. The sliding flip assembly 3 includes a push rod component 31. The push rod component 31 is a pneumatic push rod in the prior art. The push rod component 31 is provided on one side of the side plate 113. A slide table 32 is installed on the movable end of the push rod component 31. The slide table 32 has a support plate 321 parallel to the side plate 113. The support plate 321 has a slot 3211.

[0043] The clamping device 2 includes a machine base 21, on which a gripper plate seat 22 is movably mounted. The gripper plate seat 22 is used to clamp materials. The gripper plate seat 22 is a pneumatic clamping plate in the prior art. A connecting shaft 23 is provided on one side of the machine base 21. One end of the connecting shaft 23 extends to the outside of the side plate 113 and is equipped with a support seat 231. A short shaft portion 232 is provided on the support seat 231 and is sleeved in the slot 3211. A support shaft 24 is provided on the other side of the machine base 21 and is movably connected to the side plate 113.

[0044] When the slide table 32 moves relative to the push rod component 31, the side plate 113 drives the short shaft part 232 to move relative to each other. During the movement, the receiving seat 231 drives the connecting shaft 23 to rotate, so that the machine table 21 rotates synchronously.

[0045] The movement of the platform 112 on the slide rail 111 drives the machine tool 21 to move relative to it;

[0046] Through the cooperation of the push rod component 31 and the slide table 32, the clamping device 2 can have a vertical state and a horizontal state, and the vertical state and the horizontal state can be used for different processing technologies.

[0047] When the piston end of the push rod component 31 drives the slide 32 away from the push rod component 31, the clamping device 2 rotates until the gripper plate seat 22 in the clamping device 2 is parallel to the push rod component 31, and the clamping device 2 is in a vertical state.

[0048] When the piston end of the push rod component 31 drives the slide 32 to approach the push rod component 31, the clamping device 2 rotates until the gripper plate seat 22 in the clamping device 2 is perpendicular to the push rod component 31, at which point the clamping device 2 is in a horizontal state.

[0049] Based on the above structure, by installing the material to be processed between the gripper plate seats 22 of the clamping device 2, and adjusting the position of the platform 112 along the slide rail 111 according to the length of the material, the platform 112 drives the clamping device 2 to change position. After clamping, the material is processed. When it is necessary to adjust the angle relationship between the material and the processing equipment, the position of the slide 32 is changed by the push rod component 31. Since the support plate 321 on the slide 32 has a slot 3211, and the short shaft 232 on the receiving seat 231 is connected in the slot 3211, the slide 32 is moved by the push rod component 31, so that the receiving seat 231 rotates along the circumferential direction of the short shaft 232. During the rotation, the gripper plate seat 22 can rotate circumferentially, thereby changing the angle of the material and completing processing operations at different angles. This solves the problem that manual adjustment is required when adjusting the angle of the material, which can easily lead to deviations in processing accuracy.

[0050] In one embodiment, reference is made to Figures 1-4 It also includes a rotary drive component 4, which drives the gripper plate 22 to rotate in a circular motion, thereby enabling the processing of materials at different angles and positions. The rotary drive component 4 includes a drive motor 41, which is a servo drive motor in the prior art. The drive motor 41 can provide high-precision motion control, which is crucial for automated equipment that requires precise position control. The drive motor 41 is mounted on the machine base 21 and located on one side of the gripper plate 22. The output end of the drive motor 41 is keyed to a drive wheel 42. The bottom of the gripper plate 22 is connected to a main shaft that extends into the machine base 21, and a driven wheel 43 is mounted on the main shaft.

[0051] A synchronous belt 44 connects the driving wheel 42 and the driven wheel 43. With the cooperation of the synchronous belt 44, when the drive motor 41 drives the driving wheel 42 to rotate, the driven wheel 43 drives the gripper plate 22 to rotate synchronously. By connecting the driving wheel 42 and the driven wheel 43 through the synchronous belt 44, it can be ensured that the rotation of the gripper plate 22 is synchronized with the rotation of the drive motor 41, thereby improving the accuracy and repeatability of the operation and improving the transmission efficiency.

[0052] In one embodiment, reference is made to Figure 1 and Figure 2 It also includes a drag chain component 5, which is a drag belt drive driven by a motor in the prior art. An extension plate 1131 is provided on the side plate 113 away from the sliding flipping component 3. The chain part of the drag chain component 5 is connected to the extension plate 1131. Through the connection between the drag chain component 5 and the extension plate 1131, the platform 112 of the extension plate 1131 can be moved, thereby driving the clamping device 2 to move relative to it. It is suitable for some materials with a relatively long length.

[0053] In one embodiment, reference is made to Figure 1 and Figure 2 The bearing seat 11 has two contact sensing components 6 on its inner sides. The two sets of contact sensing components 6 are symmetrically distributed. The contact sensing components 6 are contact position sensors in the prior art. The position of the platform 112 can be limited by the contact sensing components 6. When the platform 112 contacts the contact sensing component 6, the start of the drag chain component 5 can be paused, thereby preventing the platform 112 from continuing to move when it reaches the limit position.

[0054] In one embodiment, reference is made to Figure 1 and Figure 2 The base 1 is provided with fixing holes 13. Several fixing holes 13 are provided and evenly distributed around the base 1. Fixing pins are movably installed on the fixing holes 13. The fixing holes 13 can be used to install the base 1 in different positions. By passing the fixing pins through the fixing holes 13 and connecting them with other components, the base 1 can be fixed. The fixing holes 13 are provided around the base 1 so that the base 1 can be fixed at all angles.

[0055] In one embodiment, reference is made to Figures 1-3 The gripper base 22 has movable jaws 221. Since the gripper base 22 is a pneumatic chuck, the movable jaws 221 can move in position by gas delivery. Several movable jaws 221 are provided and evenly distributed along the circumference of the gripper base 22. The movable jaws 221 form a clamping area for clamping materials. The movable jaws 221 are used to abut against the materials. When the materials are located between the movable jaws 221, the clamping operation of the materials is completed by the mutual approach between the movable jaws 221.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0057] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
