Description

Technical Field

[0001] The present invention relates to the technical field of fastener installation, and in particular to a workstation structure for clamping and processing workpieces. Background Art

[0002] During assembly, parts sometimes require C-shaped buckles for clamping or temporary clamping. On some processing lines, clamping has even become an important processing station. For example, after the inner shell of a car headlight is embedded in the outer shell, the inner shell and the outer shell are bonded together with glue. After the embedding, the outer shell and the inner shell are generally clamped together with a C-shaped buckle for a period of time to ensure that the glue firmly bonds the inner shell and the outer shell before the C-shaped buckle is removed. Of course, in addition to temporary clamping, there are also some workpieces in the industry that require the installation of C-shaped buckles. Therefore, the clamping process of C-shaped buckles has a great impact on the assembly efficiency of parts. At present, when installing C-shaped buckles on parts, pliers or wrenches are generally used to install the C-shaped buckles, resulting in low efficiency and affecting the operation of the entire production line process. Summary of the Invention

[0003] In view of the above, it is necessary for the present invention to provide a workstation structure for clamping workpieces, realize the automated installation of C-type buckles, and be able to continuously perform two processing steps on the same positioning fixture to improve operating efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A workstation structure for clamping workpieces includes a machine platform, a frame, a turntable, a positioning fixture, a C-shaped buckle mounting mechanism, and a C-shaped buckle. The frame is arranged across the machine platform, dividing the machine platform into a front side and a rear side of the machine platform. The turntable is rotatably arranged on the machine platform and is located below the frame. The frame correspondingly divides the turntable into a front half area and a rear half area. The front half area is installed with a positioning fixture and a C-shaped buckle mounting mechanism, and the rear half area is installed with a positioning fixture and a C-shaped buckle mounting mechanism corresponding to the front half area. The positioning fixture is used to position the workpiece to be installed with the C-shaped buckle, and the C-shaped buckle mounting mechanism is used to automatically press the C-shaped buckle onto the workpiece so that the C-shaped buckle is clamped on the workpiece.

[0006] Furthermore, the C-shaped buckle installation mechanism includes a base body, a driving member, a sliding plate and a guide pulley. The base body includes a guide groove block with a C-shaped groove on the guide groove block. The driving member includes a telescopic rod. The end of the telescopic rod is hinged to one end of the sliding plate. Two guide pulleys are installed on the sliding plate surface. A pressing buckle portion is provided on the end surface of the sliding plate opposite to the hinged end for installing the C-shaped buckle. The two guide pulleys can be slidably arranged in the C-shaped groove. The telescopic rod is extended and retracted to make the two guide pulleys slide along the track of the C-shaped groove, and the C-shaped buckle in the pressing buckle portion on the sliding plate performs the corresponding buckle track action.

[0007] Furthermore, a detachable tooling piece is installed on the end surface of one end of the sliding plate that is relatively hinged, and the buckle portion is provided on the tooling piece.

[0008] Furthermore, a hook is formed at one end of the buckle portion, and both ends of the C-shaped buckle are turned outward to form matching grooves, and the hook is used to be inserted into the matching groove of the C-shaped buckle.

[0009] Furthermore, the guide pulley is selected as a bearing, a boss is fixedly installed on the plate surface of the sliding plate, the inner ring of the bearing is fixedly sleeved on the boss, and the outer diameter of the bearing is equivalent to the groove width of the C-shaped groove.

[0010] Furthermore, the guide pulley is a column, the diameter of the column is equivalent to the width of the C-shaped groove, and the column can be installed on the plate surface of the sliding plate so as to rotate along the axis.

[0011] Furthermore, the driving member is hinged to the base.

[0012] Furthermore, a partition plate is fixedly provided on the turntable, and the partition plate is located on the dividing line between the front half area and the back half area. The partition plate rotates together with the rotation of the turntable, and a visual device is installed on the partition plate.

[0013] Furthermore, the workstation structure for clamping the workpiece includes a feeding mechanism, a picking mechanism and a post-station processing mechanism. The feeding mechanism is used to install the workpiece on the positioning fixture whose turntable is located in the front side of the machine. The post-station processing mechanism is located at the rear side of the machine and is used to process the workpiece on the positioning fixture on the rear side of the machine after the C-type buckle clamping processing is completed. The picking mechanism is used to take away the workpiece after the post-station processing is completed.

[0014] Furthermore, the positioning fixture includes a positioning column and a locking member. The positioning column is used to guide the workpiece to position and limit the lateral movement of the workpiece. The locking member is used to lock and fix the positioned workpiece and limit the longitudinal movement of the workpiece.

[0015] The beneficial effects of the present invention are:

[0016] The workstation structure for workpiece clamping provided by the present invention can realize automatic workpiece clamping processing, and by being relatively distributed in the front and rear half areas of the turntable, the workpiece can be moved from the front side of the machine to the rear side of the machine by rotating the turntable after the clamping processing in the front half area, and the positioning fixture and C-shaped buckle mounting mechanism in the rear half area are rotated to the front side of the machine to install the workpiece and perform clamping processing on the workpiece, while the workpiece at the rear side of the machine can be processed in the next step and removed after processing, and this cycle is repeated, thereby greatly improving the turnover efficiency of the clamping processing;

[0017] Furthermore, the C-shaped buckle installation mechanism pushes one end of the sliding plate to swing through the driving member, and the two guide pulleys on the sliding member will slide along the C-shaped groove on the base body, so that the other end of the sliding plate will have a corresponding rotation trajectory, and the C-shaped buckle on the buckle part on the other end of the sliding plate will be pressed against the corresponding component, thereby realizing the automatic installation of the C-shaped buckle, and after crimping, the buckle part can be detached from the C-shaped buckle; the C-shaped buckle installation mechanism provided by the present invention has a simple structure, realizes the automatic installation of the C-shaped buckle, greatly reduces labor intensity, and improves productivity.

DETAILED DESCRIPTION

[0025] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0026] like Figure 1-Figure 2As shown, an embodiment of the present invention provides a workstation structure for clamping workpieces, including a machine platform 1, a frame 2, a turntable 3, a positioning fixture 4, a C-type buckle mounting mechanism 5 and a C-type buckle 6. The frame 2 is arranged across the machine platform 1, dividing the machine platform 1 into a front side and a rear side of the machine platform. The turntable 2 is rotatably arranged on the machine platform 1 and is located below the frame 2. Correspondingly, the frame 2 divides the turntable 3 into a front half area and a rear half area. The front half area is equipped with a positioning fixture 4 and a C-type buckle mounting mechanism 5, and the rear half area is equipped with a positioning fixture 4 and a C-type buckle mounting mechanism 5 corresponding to the front half area. The positioning fixture 4 is used to position the workpiece to be installed with the C-type buckle, and the C-type buckle mounting mechanism 5 is used to automatically press the C-type buckle 6 onto the workpiece so that the C-type buckle 6 is clamped on the workpiece.

[0027] Furthermore, a partition plate 7 is fixed on the turntable 3, and is located on the dividing line between the front half area and the back half area. The partition plate 7 rotates along with the rotation of the turntable 3. A visual device is installed on the partition plate 7 for detecting the positioning accuracy of the workpiece.

[0028] Furthermore, the workstation structure for clamping the workpiece includes a feeding mechanism, a picking mechanism and a post-station processing mechanism. The feeding mechanism and the picking mechanism can use a robot arm. The feeding mechanism is used to install the workpiece on the turntable 3 on the positioning fixture 4 on the front side of the machine. The post-station processing mechanism is located on the rear side of the machine and is used to process the workpiece on the positioning fixture 4 on the rear side of the machine after the C-type buckle 6 is clamped. The picking mechanism is used to take away the workpiece after the post-station processing is completed.

[0029] The positioning fixture 4 includes a positioning post and a locking member. The positioning post is used to guide the workpiece into position. The positioning post is often a vertical rod that is inserted into the corresponding insertion hole of the workpiece to achieve lateral positioning of the workpiece, that is, to limit the lateral movement of the workpiece. The locking member is used to lock and fix the workpiece after positioning and release the lock when the workpiece needs to be removed. The locking member is usually a pneumatic cylinder. The piston rod of the cylinder extends horizontally into the locking position of the workpiece to lock the workpiece in the longitudinal direction, that is, to limit the longitudinal movement of the workpiece. The piston rod of the cylinder retracts to release the lock on the workpiece.

[0030] See also Figure 3-Figure 5 The C-shaped buckle mounting mechanism 5 is used to mount the C-shaped buckle 6 on the workpiece, and the corresponding number is set according to the number of positions required for clamping the workpiece. In this embodiment, a plurality of C-shaped buckle mounting mechanisms 5 are provided.

[0031] The C-shaped buckle 6 has a buckling opening 61 for buckling onto the surface of a part. Both ends of the C-shaped buckle 6 are turned outward to form matching grooves 62 for installation on the C-shaped buckle installation mechanism.

[0032] The C-shaped buckle mounting mechanism 5 includes a base body 10, a driving member 20, a sliding plate 30 and a guide pulley 40. The base body 10 is fixedly mounted on the machine 1; the base body 10 includes a guide groove block 11, on which a C-shaped groove 111 is provided. The driving member 20 is hinged to the base body 10 so that the driving member 20 has a certain degree of freedom of swinging space relative to the base body 10. Specifically, a base plate is fixedly connected to the bottom surface of the driving member 20, and a rod body extends from one side of the base plate and is hinged to the base body 10. The driving member 20 includes a telescopic rod 21, the end of which is hinged to one end of the sliding plate 30. Two guide pulleys 40 are installed on the surface of the sliding plate 30. A pressing portion 31 is provided on the end surface of the sliding plate 30 opposite to the hinged end for installing the C-shaped buckle 6. The two guide pulleys 40 can be slidably mounted in the C-shaped groove 111. The telescopic rod 21 is extended and retracted, so that the two guide pulleys 40 slide along the track of the C-shaped groove, and the C-shaped buckle 6 in the pressing portion 31 on the sliding plate 30 performs the corresponding buckle track action.

[0033] Furthermore, the seat body 10 includes a base 12 , and the guide groove block 11 is fixedly mounted on the base 12 by screws.

[0034] Preferably, the C-shaped groove 111 is an arc-shaped groove extending from the top to the middle of the guide groove block 11 .

[0035] Preferably, the driving member 20 is a cylinder.

[0036] Furthermore, a hinge block 211 is fixed to the end of the telescopic rod 21 , and the hinge block 211 is hinged to one end of the sliding plate 30 via a hinge pin 212 .

[0037] Furthermore, a detachable tooling piece 32 is installed on the end surface of the hinged end of the sliding plate 30 , and the buckle portion 31 is provided on the tooling piece 32 .

[0038] A hook 311 is formed at one end of the buckle portion 31 , and the hook 311 is used to be inserted into the matching groove 62 of the C-shaped buckle, so that the C-shaped buckle 6 is clamped on the buckle portion 31 through the matching groove 62 and will not fall off.

[0039] A pin hole 312 is formed on the buckle portion 31 for mounting the buckle portion 31 on the sliding plate 30 .

[0040] Preferably, the guide pulley 40 is selected as a bearing. Specifically, a boss 33 is fixedly mounted on the plate surface of the sliding plate 30, and the inner ring of the bearing is fixedly sleeved on the boss 33. The outer diameter of the bearing is equivalent to the groove width of the C-shaped groove 111.

[0041] It is understandable that the guide pulley 40 may not use a bearing, but a column, the diameter of which is equivalent to the width of the C-shaped groove 111. The column is rotatably mounted on the surface of the sliding plate 30.

[0042] When the C-clip mounting mechanism is used to mount the C-clip 6 onto a workpiece, such as a vehicle headlight assembly, comprising a headlight housing and an inner headlight housing embedded within the headlight housing, the C-clip 6 is clamped at the edge where the outer and inner housings meet to securely bond the headlight housing to the inner portion of the headlight housing. The telescopic rod 21 of the driver 20 pushes one end of the sliding plate 30 to swing, causing the two guide pulleys 40 on the sliding plate 30 to slide along the C-groove 111 on the guide groove block 11, thereby causing the other end of the sliding plate 30 to rotate in a corresponding manner. The C-clip 6 on the pressing portion 31 on the other end of the sliding plate 30 is pressed against the corresponding component, thereby achieving automatic installation of the C-clip. After crimping, the telescopic rod 21 of the driver 20 returns, causing the pressing portion 31 to disengage from the C-clip.

[0043] After the workpiece is automatically clamped and processed at the front side of the machine, the turntable 3 rotates 180°, and the workpiece after clamping and processing will be transferred to the back side of the machine, and the half area located at the back side of the machine will be transferred to the front side of the machine. After transferring to the front side of the machine, the workpiece can be fed in by the feeding mechanism and positioned by the positioning fixture 4, and then the C-type buckle installation mechanism 5 installs the C-type buckle 6 on the workpiece; at the same time, the workpiece that has been clamped and located at the back side of the machine is processed by the post-station processing mechanism, and the workpiece is taken out by the material-picking mechanism after post-processing, and the cycle continues.

[0044] In summary, the workstation structure for workpiece clamping processing of the present invention can realize automatic processing of workpiece clamping. By relatively distributing the front and rear half areas of the turntable, the workpiece can be moved from the front side of the machine to the rear side of the machine by rotating the turntable after the clamping processing of the front half area. The positioning fixture and C-type buckle installation mechanism of the rear half area are rotated to the front side of the machine to install the workpiece and perform clamping processing on the workpiece, while the workpiece on the rear side of the machine can be processed in the next step and removed after processing. The two half areas are used in a cycle and the corresponding processing is performed simultaneously, which greatly improves the operating efficiency. In addition, the C-type buckle installation mechanism provided by the present invention has a simple structure and realizes the automatic installation of the C-type buckle, which greatly reduces the labor intensity and improves the productivity.

[0045] The above-described embodiments merely illustrate the implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
