Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a product anti-scratch, anti-tilt, and anti-fall gripper device. Background Technology

[0002] A fixture is a device used in machining, assembly, and other processes to quickly, conveniently, and safely install and hold workpieces, thereby facilitating and ensuring the smooth progress of the process.

[0003] When the surface of the product being clamped is an external surface and the clamping area is curved, the existing conventional contour clamping method cannot meet the requirements for scratch prevention and precise positioning. The existing contour clamping has a high rate of abnormality and instability in actual production.

[0004] In addition, conventional grippers typically use pilot valves to prevent falling when the air or power is cut off, but this only solves the problem for a short time. If the time exceeds 1 hour, there is still a risk of falling, which could damage the product. Utility Model Content

[0005] To address the aforementioned issues, this application provides a product gripper device with a reasonable structure that prevents scratches, tilting, and falling, thereby effectively avoiding scratches caused by sliding friction, ensuring stable and reliable clamping, protecting the appearance, and conforming to the product's mounting reference surface. In particular, it can clamp in curved clamping areas, making it highly practical.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A product anti-scratch, anti-tilt, and anti-fall gripper device includes parallel columns spaced apart, a lifting platform mounted on the columns, a tilting platform mounted on the lifting platform, and gripper assemblies that move horizontally towards or away from each other mounted on the tilting platform via parallel pneumatic grippers; it also includes an elastic abutment assembly located between the two sets of gripper assemblies, the elastic abutment assembly and the gripper assemblies being located above and below the product being gripped in the Z direction respectively, the elastic abutment assembly driving the gripped part to adhere to the gripper assembly, and the contact surface between the gripped part and the gripper assembly forming a reference surface.

[0008] As a further improvement to the above technical solution:

[0009] The elastic abutment components are arranged corresponding to the gripper components, and the elastic abutment components are spaced apart at the four corners of the product.

[0010] The tops of the two sets of elastic abutment components are equipped with positioning pins, which are fitted into the positioning holes of the product.

[0011] The structure of a single set of elastic abutment components is as follows: it includes a support column, a sleeve is fitted on the top of the support column, a spring is installed between the bottom end of the sleeve and the support column, and the top surface of the sleeve forms the abutment surface that contacts the product; in two sets of elastic abutment components, a positioning pin is installed at the top of the support column located inside the sleeve, and the positioning pin extends upward out of the sleeve.

[0012] The structure of a single gripper assembly is as follows: it includes a gripper seat installed on the output part of the parallel pneumatic gripper, a vertical plate is detachably installed at the end of the gripper seat, and L-shaped grippers are installed at both ends of the side of the vertical plate. The inner side of the horizontal arm of the L-shaped gripper is in contact with the product.

[0013] An L-shaped fitting is installed in the middle of the vertical plate, and sliding parts are installed at intervals on the gripper seat to form an inverted T-shaped groove for sliding fitting of the fitting; a retractable plunger is installed through the gripper seat toward the fitting.

[0014] A quick-change seat is installed on the flipping table located on the outer side of the parallel pneumatic gripper, and multiple sets of elastic abutment components are installed on the quick-change seat.

[0015] The quick-change seat has a U-shaped structure, and outer steps are respectively provided on the outer edges of the opposite two sides of the quick-change seat; it also includes a pressure strip, which is pressed onto the outer steps of the quick-change seat and locked and fixed to the flip table.

[0016] The lifting platform is driven by a lifting drive to move up and down relative to the column.

[0017] The tilting platform is tilted relative to the lifting platform by a tilting mechanism. The tilting mechanism consists of a support base installed on the external lifting platform on both sides of the tilting platform, a rotating shaft installed between the support base and the end side plate of the tilting platform, a gear fitted on the outer end of the rotating shaft, and a vertically arranged rack meshing with the gear. A power base is installed on the side of the lifting platform, a linear drive power is installed on the power base, the output end of the linear drive power is connected to the rack, and the rack is slidably mounted on the power base.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model achieves product gripping and holding through a combination of elastic abutment components and gripper components. In particular, it can grip curved gripping areas, effectively avoiding scratches caused by sliding friction. The gripping is stable and reliable, ensuring the appearance of the product. Moreover, it fits the product's mounting reference surface, meeting the product's anti-slip and precise positioning needs, and has good practicality.

[0020] This utility model also has the following advantages:

[0021] The device employs two gripper assemblies on both sides, combined with corresponding elastic abutment components, positioned above and below the product in the Z direction to clamp the product in a bottom-supporting manner. This effectively prevents the product from tilting during the flipping process. Furthermore, the clamping direction is perpendicular to the driving direction of the parallel pneumatic gripper, so that the gripper can remain in its original position to support the product even when power or air supply is interrupted, effectively preventing the product from falling due to unexpected power or air supply interruptions.

[0022] By setting positioning pins in two sets of relatively arranged elastic abutment components, the positioning pins are fitted into the positioning holes of the product, thereby achieving precise positioning of the product in the XY direction during clamping.

[0023] The L-shaped gripper in the gripper assembly is quickly assembled at the output end of the parallel pneumatic gripper via the mounting parts and sliding parts. The elastic abutment component is quickly assembled on the flip table via the quick-change seat. Thus, the quick-change of the gripper assembly and the elastic abutment component can be matched to the product changeover requirements, which is convenient for actual operation and maintenance and improves the flexibility of use.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, this embodiment of a product anti-scratch, anti-tilt, and anti-fall gripper device includes parallel columns 1 arranged at intervals, a lifting platform 3 mounted on the columns 1, a tilting platform 4 mounted on the lifting platform 3, and gripper assemblies 8 that move horizontally towards or away from each other mounted on the tilting platform 4 via parallel pneumatic grippers 6; it also includes an elastic abutment component 7 located between the two sets of gripper assemblies 8, the elastic abutment component 7 and the gripper assemblies 8 being located above and below the product being gripped in the Z direction respectively, the elastic abutment component 7 driving the gripped part to adhere to the gripper assembly 8, and the contact surface between the gripped part and the gripper assembly 8 forming a reference surface.

[0038] In this embodiment, the product is gripped and held by the elastic abutment component 7 combined with the gripper component 8. In particular, it can be held in the curved gripping area, which effectively avoids scratches caused by sliding friction. The gripping is stable and reliable, protects the appearance, and fits the product's mounting reference surface.

[0039] In this embodiment, two gripper assemblies 8 are used, combined with corresponding elastic abutment assemblies 7, which are located above and below the product in the Z direction, respectively, to grip the product in a bottoming manner, effectively preventing the product from tilting during the flipping process. Moreover, the gripping direction is perpendicular to the driving direction of the parallel air gripper 6, so that the gripper can always remain in the original position to support the product when the power and air are cut off, effectively preventing the product from falling due to accidental power and air failure.

[0040] The elastic abutment component 7 is arranged corresponding to the gripper component 8, so that it acts on the clamped part of the product from above and below. The elastic abutment component 7 is arranged at intervals at the four corners of the product, so that the elastic abutment component 7 combined with the gripper component 8 can achieve stable and reliable clamping of the product.

[0041] The top of the two sets of elastic abutment components 7 are equipped with positioning pins 74, which are fitted into the positioning holes of the product.

[0042] By setting the positioning pins 74 in the two sets of elastic abutment components 7 arranged opposite to each other, the positioning pins 74 are fitted into the positioning holes of the product, thereby achieving precise positioning of the product in the XY direction when clamped.

[0043] like Figure 3As shown, the structure of a single set of elastic abutment components 7 is as follows: it includes a support column 71, a sleeve 73 is fitted on the top of the support column 71, a spring 72 is installed between the bottom end of the sleeve 73 and the support column 71, and the top surface of the sleeve 73 forms the abutment surface that contacts the product; in two sets of elastic abutment components 7, a positioning pin 74 is installed on the top of the support column 71 located inside the sleeve 73, and the positioning pin 74 extends upward out of the sleeve 73.

[0044] In actual use, the positioning pin 74 is fitted into the positioning hole at the clamping part of the product, and the top surface of the sleeve 73 contacts and abuts against the product. Under the elastic action of the spring 72, the sleeve 73 applies force to the product to make it fit against the gripper assembly 8.

[0045] like Figure 4 As shown, the structure of the single gripper assembly 8 is as follows: it includes a gripper seat 84 installed on the output part of the parallel pneumatic gripper 6, a vertical plate 82 is detachably installed at the end of the gripper seat 84, and L-shaped grippers 81 are installed at both ends of the side of the vertical plate 82. The inner side of the horizontal arm of the L-shaped gripper 81 is attached to the product.

[0046] In this embodiment, the L-shaped gripper 81 can be quickly changed and installed at the output end of the gripper 84 and the parallel pneumatic gripper 6 by the detachable installation between the gripper seat 84 and the vertical plate 82, which is suitable for production maintenance and product changeover needs, and the inner side of the L-shaped gripper 81 and the product form a reference surface.

[0047] An L-shaped fitting 86 is installed in the middle of the vertical plate 82. Sliding parts 83 are installed at intervals on the gripper seat 84, forming an inverted T-shaped groove for the fitting 86 to slide and fit. A retractable plunger 85 is installed through the gripper seat 84 toward the fitting 86.

[0048] In actual operation, the retractable plunger 85 is removed, and the L-shaped gripper 81 is quickly disassembled by sliding the fitting 86 relative to the sliding part 83 along the inverted T-slot. The installation process is the reverse of the disassembly process. After the fitting 86 is slidably installed onto the sliding part 83, the retractable plunger 85 is passed through the gripper seat 84 and installed upward onto the fitting 86 to achieve locking and fixation between the fitting 86 and the gripper seat 84.

[0049] In this embodiment, the retractable plunger 85, also known as a knob plunger, spring pin, etc., is a standard product currently available on the market, which can be quickly locked in place.

[0050] A quick-change seat 5 is installed on the tilting table 4 located on the outer side of the parallel pneumatic gripper 6, and multiple sets of elastic abutment components 7 are installed on the quick-change seat 5. Thus, the elastic abutment components 7 can be quickly installed and replaced as a whole through the quick-change seat 5, which is convenient for actual operation and maintenance.

[0051] like Figure 5As shown, the quick-change seat 5 has a U-shaped structure to realize and ensure the layout and installation of the four sets of elastic abutment components 7; the outer edges of the opposite sides of the quick-change seat 5 are respectively provided with outer steps 51; it also includes a pressure strip 52, which is pressed onto the outer steps 51 of the quick-change seat 5, and the pressure strip 52 is locked and fixed to the flip table 4, so that the quick-change seat 5 can be quickly positioned and installed through the pressure strip 52.

[0052] In this embodiment, sensors, pins, etc. can also be installed between the tilt table 4 and the quick-change seat 5 to achieve horizontal positioning.

[0053] In this embodiment, the L-shaped gripper 81 in the gripper assembly 8 is quickly assembled at the output end of the parallel pneumatic gripper 6 via the mounting part 86 and the sliding part 83. The elastic abutment component 7 is quickly assembled on the flip table 4 via the quick-change seat 5. Thus, the quick-change of the gripper assembly 8 and the elastic abutment component 7 can be matched to the product changeover requirements, which is convenient for actual operation and maintenance and improves the flexibility of use.

[0054] The lifting platform 3 is driven by the lifting drive 31 to move up and down relative to the column 1. Thus, the lifting action of the lifting platform 3 can be combined with the elastic abutment component 7 and the gripper component 8 to clamp the product.

[0055] The tilting platform 4 is tilted relative to the lifting platform 3 by the tilting mechanism 2. The tilting mechanism 2 has the following structure: it includes a support seat 21 installed on the external lifting platform 3 on both sides of the tilting platform 4. A rotating shaft 22 is installed between the support seat 21 and the end side plate 41 of the tilting platform 4. A gear 23 is fitted on the outer end of the rotating shaft 22. The gear 23 is meshed with a vertically arranged rack 24. A power seat 26 is installed on the side of the lifting platform 3. A linear drive power 25 is installed on the power seat 26. The output end of the linear drive power 25 is connected to the rack 24. The rack 24 is slidably mounted on the power seat 26.

[0056] In this embodiment, the linear drive power 25 operates, causing the rack 24 to move upward or downward relative to the power seat 26, causing the gear 23 meshing with the rack 24 to rotate, thereby driving the tilting table 4 to tilt via the rotating shaft 22.

[0057] In this embodiment, the lifting drive power 31 and the linear drive power 25 are existing standard products with linear output, including but not limited to cylinders, hydraulic cylinders, electric cylinders, etc.

[0058] The method of using this utility model is as follows:

[0059] Initially, the product is placed on an external object below the lifting platform 3. The external object is a support component such as a work platform or a turntable used to support the product. The parallel pneumatic gripper 6 and the elastic abutment component 7 on the tilting platform 4 face downwards. With the operation of the lifting drive 31, the lifting platform 3 moves downwards, causing the bottom end of the elastic abutment component 7 to gradually approach and contact the product being clamped. The positioning pin 74 is fitted into the positioning hole of the product, and the bottom end face of the sleeve 73 contacts and abuts against the product. The parallel pneumatic gripper 6 operates, driving the two side gripper assemblies 8 to move towards each other until the horizontal arm of the L-shaped gripper 81 moves to below the product being clamped. As the lifting drive 31 reverses its operation, the product is detached from the external object. Due to the elastic abutment force of the elastic abutment component 7 and the combination of the gripper assembly 8, the product is reliably clamped in the Z direction. Then, the tilting mechanism 2 operates, driving the tilting platform 4 to tilt, for example, tilt 180°. The product is tilted above the tilting platform 4 for processing, assembly, and other operations.

[0060] This invention effectively avoids scratches caused by sliding friction, provides stable and reliable clamping, protects the appearance, and fits the product's mounting reference surface. In particular, it can clamp in curved clamping areas, making it highly practical.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
