Description

Technical Field

[0001] This application belongs to the field of positioner equipment technology, and more specifically it relates to a quick-change fixture structure for a positioner. Background Technology

[0002] In industrial fields such as machining, welding, and assembly, positioners are core equipment for adjusting workpiece posture, and the efficiency of their fixture structure switching directly affects the flexible production capacity of the production line. A quick-change fixture structure is used to achieve rapid clamping and positioning of workpieces of different specifications and shapes, and is a key component for improving the versatility and production efficiency of positioners. However, existing positioner fixture structures have the following shortcomings in practical applications;

[0003] When changing different workpiece fixtures, the fixture needs to be installed onto the fixture mounting base with bolts, which is a relatively troublesome operation and results in a long fixture change time, directly affecting production efficiency.

[0004] Based on this, this application designs a quick-switching fixture structure for a positioner. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-change fixture structure for a positioner, which has the advantage of being able to quickly change different fixtures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-switching fixture structure for a positioner, comprising two fixing components and a fixture mounting base; the two fixing components are respectively disposed at the ends of the two main arms of the positioner; the two ends of the fixture mounting base are detachably snapped onto the two fixing components;

[0007] The fixing component includes a rotating disk connected to the inner side wall of the main arm and driven to rotate by a motor. A connecting plate is provided on the side wall of the rotating disk, and a through hole is provided in the middle of the connecting plate. Both ends of the clamp mounting base are connected to mating plates. The lower end face of the mating plate is provided with a snap-fit ​​pin that can be inserted into the through hole. The lower end face of the connecting plate is provided with a locking component for fixing the snap-fit ​​pin.

[0008] In a preferred embodiment: the locking assembly includes a cylinder, a snap-fit ​​plate, and a slide rail. There are two slide rails, symmetrically arranged on both sides of the through hole of the connecting plate. The two ends of the snap-fit ​​plate are respectively slidably arranged in the slide grooves of the two slide rails. The cylinder is fixedly installed on the lower end face of the connecting plate, and the movable end of the cylinder is connected to one end of the snap-fit ​​plate. The snap-fit ​​plate is provided with snap-fit ​​holes, and the lower part of the snap-fit ​​pin is provided with a snap-fit ​​groove.

[0009] In a preferred embodiment: the snap-fit ​​hole is gourd-shaped, that is, one end of the snap-fit ​​hole has a larger diameter and the other end has a smaller diameter. When the snap-fit ​​pin is inserted, the larger diameter end coincides with the through hole, which facilitates the insertion of the snap-fit ​​pin; when fixed, the snap-fit ​​plate moves so that its smaller diameter end coincides with the through hole, locking the snap-fit ​​pin in the slot.

[0010] In a preferred embodiment: the slide rail is L-shaped, and its upper end is fixedly connected to the lower end face of the connecting plate, thereby forming a groove between the slide rail and the connecting plate.

[0011] In a preferred embodiment: the lower end face of the connecting plate is provided with sensors at both ends of the slide rail. The sensors are connected to the cylinder signal. When the cylinder drives the snap-fit ​​plate to the position of the sensor, the cylinder stops working to avoid excessive extension and retraction of the cylinder, which would cause misalignment between the through hole on the connecting plate and the snap-fit ​​hole on the snap-fit ​​plate, resulting in the snap-fit ​​pin being unable to be inserted.

[0012] In a preferred embodiment: the outer end of the docking plate is also provided with a limiting groove, and the outer side of the rotating disk is provided with a limiting block that matches the limiting groove; when the fixture mounting base is installed, the limiting groove and the limiting block are engaged, which facilitates the precise installation of the fixture mounting base and also prevents its axial rotation.

[0013] Compared with the prior art, this application has the following beneficial effects:

[0014] This application uses a detachable fixture mounting base connected to the main arm of the positioner, which facilitates the quick replacement of fixtures for different workpieces and improves welding efficiency. At the same time, the locking assembly can quickly fix the replaced fixture mounting base, reducing replacement time. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0026] In the description of this disclosure, it should be understood that the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the disclosed product is in use, or the orientation or positional relationship commonly understood by those skilled in the art.

Therefore, they should not be construed as limitations on this disclosure.

[0027] A quick-change fixture structure for a positioner, such as Figures 1-6 As shown, it includes two fixing components 2 and a clamp mounting base 3; the two fixing components 2 are respectively set at the ends of the two main arms 1 of the positioner; the two ends of the clamp mounting base 3 are detachably snapped onto the two fixing components 2.

[0028] Based on the above embodiments, the fixing component 2 includes a rotating disk 201, which is connected to the inner side wall of the main arm 1 and is driven to rotate by a motor. A connecting plate 202 is provided on the side wall of the rotating disk 201. A through hole 205 is provided in the middle of the connecting plate 202 and a locking component is provided on the lower end face. Both ends of the clamp mounting base 3 are connected to a docking plate 301. A snap-fit ​​pin 302 is provided on the lower end face of the docking plate 301. During installation, the snap-fit ​​pin 302 is inserted into the through hole 205 and fixed by the locking component.

[0029] In one specific embodiment, such as Figures 3-5As shown, the locking assembly includes a cylinder 203, a snap-fit ​​plate 204, and a slide rail 206. There are two slide rails 206 symmetrically arranged on both sides of the through hole 205 of the connecting plate 202. The two ends of the snap-fit ​​plate 204 are slidably arranged in the slide grooves of the two slide rails 206 respectively. The cylinder 203 is fixedly installed on the lower end face of the connecting plate 202. The movable end of the cylinder 203 is fixed to one end of the snap-fit ​​plate 204. The extension and retraction of the cylinder 203 can drive the snap-fit ​​plate 204 to move within the slide rail 206. The snap-fit ​​plate 204 is provided with a snap-fit ​​hole 2041, and the lower part of the snap-fit ​​pin 302 has a snap-fit ​​groove.

[0030] Based on the above embodiment, the snap-fit ​​hole 2041 is gourd-shaped, that is, one end of the snap-fit ​​hole 2041 has a large diameter and the other end has a small diameter. When the snap-fit ​​pin 302 is inserted, the large diameter end coincides with the through hole 205, which facilitates the insertion of the snap-fit ​​pin 302; when it is necessary to fix the clamp mounting base 3, the piston rod of the cylinder 203 retracts and drives the snap-fit ​​plate 204 to move, so that its small diameter end coincides with the through hole 205, which can form a locking state with the snap-fit ​​pin 302's slot.

[0031] It should be noted that in this embodiment, the slide rail 206 is L-shaped, and its upper end is fixedly connected to the lower end face of the connecting plate 202, thereby forming a groove between the slide rail and the connecting plate 202.

[0032] In one specific embodiment, such as Figure 3 , Figure 5 As shown, sensors 207 connected to the cylinder 203 are installed on both ends of the slide rail 206 on the lower end face of the connecting plate 202. When the cylinder 203 moves the snap-fit ​​plate 204 to the position of the sensor 207, the cylinder 203 stops working to prevent the cylinder 203 from over-extending and causing the through hole 205 on the connecting plate 202 and the snap-fit ​​hole 2041 on the snap-fit ​​plate 204 to misalign, thus preventing the snap-fit ​​pin 302 from being unable to be inserted into the through hole 205.

[0033] In one specific embodiment, such as Figure 1 , Figure 4 As shown, the outer end of the docking plate 301 is also provided with a limiting groove 303, and the outer side of the rotating disk 201 is provided with a limiting block that matches the limiting groove 303. When the fixture mounting base 3 is installed, the limiting groove 303 and the limiting block are engaged, which facilitates the precise installation of the fixture mounting base 3 and prevents its axial rotation.

[0034] The working process and beneficial effects of this utility model are as follows:

[0035] In use, different workpiece fixtures have their own fixture mounting base 3 connected to them. When changing workpiece fixtures, simply install the corresponding fixture mounting base 3 onto the fixing component 2 of the main arm 1, so that the snap-fit ​​pin 302 is inserted into the through hole 205 and the snap-fit ​​plate 204, and then the cylinder 203 drives the snap-fit ​​plate 204 to move, locking the snap-fit ​​pin 302 in the slot, thus fixing the fixture mounting base 3. When disassembling, simply reverse the operation.

[0036] In summary, this application connects the detachable fixture mounting base 3 to the main arm 1 of the positioner, facilitating the rapid replacement of fixtures for different workpieces and improving welding efficiency. At the same time, the locking assembly can quickly fix the replacement fixture mounting base 3, reducing replacement time.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
