Description

Technical Field

[0001] The invention relates to the field of turnover mechanisms, in particular to a mechanism for realizing turnover and pressing products. Background Art

[0002] Due to product structure size and process requirements, products often need to be turned over during production and a mechanism is required to press and position the products.

[0003] In order to prevent the product from slipping when the flipping mechanism flips, the product needs to be pressed and positioned. The pressing device (such as a vise) of the existing flipping mechanism first presses and fixes the product on the flipping table, and then performs the flipping action. However, in some cases, the product cannot be pressed before flipping, so the existing flipping mechanism is not applicable. Therefore, it is necessary to design a mechanism in which the product is not pressed before flipping, but is pressed at the same time when flipping. Although some existing flipping mechanisms use cylinders to achieve the solution of pressing the product when flipping, this method has the disadvantages of high cost, large size, and occupying the space of other production components. Summary of the invention

[0004] The present invention aims to provide a mechanism for realizing flipping and pressing a product, so as to provide a mechanism for pressing a product at the same time when flipping.

[0005] The specific plan is as follows:

[0006] A mechanism for realizing flipping and pressing a product, comprising a base, a flip table with both ends coaxially connected to the base, a power source drivingly connected to the flip table, and a pressing member slidably connected to the side of the flip table;

[0007] The lower part of the pressing member is slidably connected to a side surface of the turning table and can slide in a direction perpendicular to the turning table surface. The upper part of the pressing member extends to the turning table surface and is arranged opposite to the workpiece located on the turning table surface.

[0008] The base is provided with a first limiter and a second limiter on two opposite sides corresponding to the flipping direction of the flipping table;

[0009] When the turning table is in a horizontal state, the second limiting member abuts against the bottom of the pressing member, and the upper part of the pressing member is higher than the workpiece;

[0010] When the turning table is in the turning state, the first limiter abuts against one side of the turning table to limit its turning angle, the bottom of the pressing member is separated from the second limiter, and the pressing member slides down under its gravity, so that the upper part of the pressing member presses the workpiece.

[0011] In some embodiments, the base has a supporting platform, and when the turning table is in a horizontal state, the supporting platform horizontally supports the bottom of the turning table.

[0012] In some embodiments, the clamping member includes a workpiece clamping member, a clamping slide rail and a slider. The clamping slide rail is fixedly installed on one side of the turning table, and the slider is slidably connected to the clamping slide rail. The workpiece clamping member includes a fixing portion fixedly connected to the slider, a clamping portion located above the turning table surface and opposite to the workpiece, and an extending portion connecting the fixing portion and the clamping portion. The fixing portion of the workpiece clamping member is fixedly installed on the slider.

[0013] In some embodiments, it also includes a first clamping limiter and a second clamping limiter, wherein the first clamping limiter is fixedly mounted on one side of the turning table, and the second clamping limiter is elastically connected to the bottom of the first clamping limiter through an elastic member.

[0014] In some embodiments, the first clamping limiter and the second clamping limiter have coaxially arranged blind holes on their facing surfaces, the axial directions of the two blind holes are arranged parallel to the sliding direction of the slider, and the elastic member is coaxially installed in the blind holes of the first clamping limiter and the second clamping limiter.

[0015] In some embodiments, the fixing portion of the workpiece pressing piece has a protruding flange, and when the turning platform is in a turning state, the flange stops at the first clamping stopper to limit the distance that the workpiece pressing piece slides down.

[0016] In some embodiments, the first limiting member and the second limiting member both include a fixing block and a limiting screw mounted on the fixing block, and the limiting screw can adjust the length thereof extending relative to the fixing block.

[0017] In some embodiments, the turning platform is a turning slide rail having a concave slideway, and the workpiece moves in the slideway through a carrier.

[0018] In some embodiments, the base includes two support bases arranged opposite to each other, and the two support bases have a front slide rail and a rear slide rail located on the front and rear ends of the flip slide rail. The front and rear ends of the flip slide rail are pivotally connected to the front slide rail and the rear slide rail through a rotating shaft. When the flip slide rail is in an unflipped state, the front slide rail, the flip slide rail and the rear slide rail together form a slide located on the same horizontal plane.

[0019] In some embodiments, both side walls of the flip slide rail have limiting portions extending into the slide rail, and the limiting portions are used to limit the carrier when the flip slide rail flips.

[0020] The mechanism for flipping and pressing products provided by the present invention has the following advantages compared with the prior art: when the flip table is flipped, the pressing member on the flip table uses its own gravity to press the workpiece on the flip table surface, so that the mechanism can press the workpiece without the aid of tools such as cylinders and vises. Therefore, the pressing member can be designed to be smaller and will not occupy the space of other production parts and mechanisms, and is suitable for miniaturized flipping mechanisms; moreover, the pressing member has a simple structure, is easy to implement, and has cost advantages.

[0032] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0034] like Figure 1-Figure 6 As shown, this embodiment provides a mechanism for flipping and pressing a product, and the mechanism includes a base 1 , a rotating assembly 2 mounted on the base 1 , and a pressing assembly 3 .

[0035] Specifically, the base 1 includes two support bases arranged opposite to each other. For the convenience of description, in this embodiment, the two support bases are respectively defined as a left support base 10 and a right support base 11. The left and right support bases have a front slide rail 12 and a rear slide rail 13 located at the front and rear ends thereof.

[0036] The rotating assembly 2 includes a flip rail 20 and a flip cylinder 21. The flip rail 20 is located between the front rail 12 and the rear rail 13, and the front and rear ends of the flip rail 20 are pivotally connected to the front rail 12 and the rear rail 13 through a rotating shaft, so that the flip rail 20 can rotate relative to the rotating shaft. The bottom of the cylinder body of the flip cylinder 21 is fixed to the left support seat 10, and the free end of the piston rod of the flip cylinder 21 is driven and connected to the right side of the bottom of the flip rail 20. When the piston rod of the flip cylinder 21 extends, the flip rail 20 performs a counterclockwise flipping action with the rotating shaft as the center under the action of the flip cylinder 21.

[0037] The left side of the flipping slide 20 has a first stopper 101 fixed on the left support seat 10, and the first stopper 101 limits the counterclockwise flipping angle of the flipping slide 20. The right support seat 11 has a support platform 110, and the support platform 110 supports the flipping slide 20 when the flipping slide 20 is not flipped, so that the flipping slide 20 is in a horizontal state. When the flipping slide 20 is in a non-flipped state, the front slide 12, the flipping slide 20 and the rear slide 13 together form a slideway 40 located on the same horizontal plane, and the workpiece 4 can move in a straight line on the slideway 40.

[0038] The clamping assembly 3 includes a workpiece clamp 30, a clamping slide 31 and a slider 32. The clamping slide 31 is fixedly installed on the right side of the flip slide 20, and the slider 32 is slidably connected to the clamping slide 31, and the slider 32 can slide on the clamping slide 31 in the direction of the vertical slide 40. The workpiece clamp 30 includes a fixing portion 300 fixedly connected to the slider 32, a clamping portion 301 located above the slide 40 and facing the workpiece 4, and an extension portion 302 connecting the fixing portion 300 and the clamping portion 301. The fixing portion 300 of the workpiece clamp 30 is fixed on the slider 32, so that the workpiece clamp 30 can slide on the clamping slide 31 with the slider 32.

[0039] The right support seat 11 is provided with a second stopper 111. When the flip rail 20 is not flipped and kept horizontal, the bottom of the workpiece pressing member fixing portion 300 abuts against the second stopper 111, so that the slider 32 is in a stationary state on the clamping rail 31, that is, the second stopper 111 limits the sliding of the slider 32 on the clamping rail 31. At this time, the clamping portion 301 of the workpiece pressing member 30 is located above the workpiece 4, with a certain distance from the top of the workpiece 4, that is, when the flip rail 20 is not flipped, the workpiece pressing member 30 does not contact the workpiece 4, and the workpiece pressing member 30 does not clamp the workpiece 4.

[0040] refer to Figure 7-Figure 10 , the flipping slide 20 flips counterclockwise at a certain angle under the action of the flipping cylinder 21, and is abutted against the first stopper 101 to complete the flipping of the flipping slide 20. When the flipping slide 20 flips, the pressing slide 31 flips counterclockwise with the flipping slide 20, and the flipping of the pressing slide 31 drives the slider 32 on the flipping slide 20 to flip together, so that the fixed part 300 of the workpiece pressing piece 30 is lifted up with the flipping, thereby disengaging from the second stopper 111, but under the action of the gravity of the workpiece pressing piece 30 and the slider 32, the slider 32 slides downward on the pressing slide 31, so that the pressing part 301 of the workpiece pressing piece 30 moves down and abuts against the top of the workpiece 4, so as to achieve the clamping of the workpiece 4.

[0041] When the turning slide 20 is turned over, the workpiece pressing member 30 on the turning slide 20 presses the workpiece 4 on the turning slide 20 by the gravity of the workpiece pressing member 30 and the slider, so that the pressing assembly can be designed to be smaller and will not occupy the space of other production parts and mechanisms, and is suitable for miniaturized turning mechanisms. Moreover, the pressing assembly has a simple structure, is easy to implement, and has cost advantages.

[0042] In one embodiment, reference Figure 1-Figure 10 The clamping assembly 3 further includes a first clamping stopper 33 and a second clamping stopper 34, wherein the first clamping stopper 33 is fixedly mounted on the right side of the flip rail 20, and the second clamping stopper 34 is elastically connected to the bottom of the first clamping stopper 33 through an elastic member 35. In this embodiment, the elastic member 35 is a spring for example.

[0043] When the flip slide 20 is not flipped, the second clamping stopper 34 abuts against the second stopper 111, and the bottom of the workpiece clamp fixing portion 300 abuts against the second clamping stopper 34, so that the slider 32 is in a stationary state on the clamping slide 31. Since the second clamping stopper 34 is elastically connected to the bottom of the first clamping stopper 33, the elastic member 35 can play a role in shock absorption.

[0044] Specifically, when the flip slide 20 is in the flipping state, the second clamping stopper 34 will slide downward due to its own gravity, but due to the action of the elastic member 35, the sliding displacement distance is limited. Under the action of gravity, the workpiece clamp 30 and the slider 32 will continue to slide downward on the clamping slide 31 when the flip slide 20 flips, so the bottom of the workpiece clamp fixing part 300 will contact the second clamping stopper 34 multiple times, and the elastic member 35 can absorb the impact when the workpiece clamp 30 contacts the second clamping stopper 34, so that the workpiece clamp 30 can press the product while the flip slide 20 flips, and reduce the shaking of the product, so that the position of the product is stable after flipping.

[0045] Preferably, the first clamping limiter 33 and the second clamping limiter 34 have coaxially arranged blind holes on their facing surfaces, and the axial directions of the two blind holes are arranged parallel to the sliding direction of the slider on the clamping slide rail 31. The two ends of the above-mentioned elastic member 35 are respectively installed in the blind holes of the first clamping limiter 33 and the second clamping limiter 34, so that the elastic member 35 is subjected to axial force, which has a better shock absorbing effect, can better reduce the shaking of the product, and make the position of the product more stable after flipping.

[0046] Another preferred embodiment is that the front and rear sides of the workpiece pressing piece fixing part 300 also have flanges 303 protruding outward. When there is no workpiece to be flipped on the flip slide rail 20, the flanges 303 on both sides of the fixing part 300 will stop on the first clamping limit member 33 to prevent the workpiece pressing piece from continuing to slide downward.

[0047] In one embodiment, the structures of the first limit member 101 and the second limit member 111 are roughly the same, both of which include a fixed block and a limit screw installed on the fixed block. The limit screw on the fixed block can adjust the length extended from its top, thereby adjusting the flipping angle of the flip slide rail 20 and the height of the clamping assembly 3 sliding down, so that it can adapt to workpieces of different sizes and has better applicability.

[0048] In another embodiment, the tops of the two side walls of the flipping slide rail 20 also have a limiting portion 201 extending into the slide rail 40, and the workpiece 4 is limited to be installed on the carrier 41 in the horizontal direction. The limiting portion 201 is used to limit the carrier 41 when the flipping slide rail 20 is flipped to prevent the carrier 41 from moving during flipping, thereby ensuring the stability of the workpiece 4 during flipping.

[0049] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
