[0031] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the exemplified embodiments are not intended to limit the present utility model.
[0032] Embodiment
[0033] Refer to Figures 1 to 11 As shown, the present utility model provides a jacking and clamping mechanism, which includes a jacking assembly 1, a streamline assembly 2, a clamping assembly 3, a carrier 4 and a limiting member 5; the carrier 4 is used to cooperate with and fix the product, the streamline assembly 2 is used to support the movement of the carrier 4 and the product, and is limited by the limiting member 5; the jacking assembly 1 is used to realize the jacking of the product, and the clamping assembly 3 realizes the clamping of the product while jacking; in the jacking and clamping mechanism of the present utility model, the clamping assembly 3 and the jacking assembly 1 simultaneously realize the jacking and clamping actions through a set of power sources, with a compact structure and smaller space occupation, and can improve production efficiency.
[0034] Specifically, refer to Figure 7 As shown, the jacking assembly 1 includes a driving part 11 and a jacking platform 12. The driving part 11 is set as a jacking cylinder, and the jacking platform 12 is located at the top of the driving part 11 and connected to the execution end of the jacking cylinder. The jacking platform 12 includes a jacking bottom plate 1201 and a jacking positioning plate 1202 that are closely arranged in the vertical direction. The jacking positioning plate 1202 has a positioning pin 13 that can cooperate with the carrier 4, and the carrier 4 has a matching positioning hole 43. Before the driving part 11 performs the jacking action, the carrier 4 and the product move on the streamline assembly 2, and the jacking platform 12 is arranged opposite to the product in the vertical direction and has a certain gap.
[0035] Further, the jacking assembly 1 of the jacking and clamping mechanism further includes a mounting seat 14 and a slide rail 15; the fixed seat 21 is located at the bottom of the driving part 11; the slide rail 15 is located on both sides of the driving part 11 in the transmission direction of the streamline assembly 2 to support the jacking platform 12, and the slide rail 15 also extends in the vertical direction.
[0036] Specifically, the streamline assemblies 2 are symmetrically arranged on both sides of the jacking assembly 1; the streamline assemblies 2 include fixed seats 21 and synchronous belts 22. The synchronous belts 22 on both sides are arranged opposite to each other and are located on the side of the streamline assembly 2 facing the jacking assembly 1. The synchronous belts 22 are used to support the movement of the carrier 4 and the product. The streamline assembly 2 further includes a motor for controlling the synchronous belt 22.
[0037] Further, the limiting member 5 is on one side in the extending direction of the synchronous belt 22 and is oppositely arranged with respect to the carrier 4 in the extending direction of the synchronous belt 22; the carrier 4 and the product are placed on the synchronous belt 22 and move therewith until they abut against the limiting member 5 and stop.
[0038] Specifically, referring to Figure 10 As shown, the carrier 4 is hollow, and stoppers 41 for limiting cooperation with the product are arranged at the four corners of the carrier 4. An elastic member 42 is further protrudingly arranged on the stopper 41 facing the hollow area for cooperating with and assembling the product.
[0039] Specifically, referring to Figure 3 and Figure 6 As shown, the clamping assembly 3 includes two groups of link rods. The two groups of link rods are symmetrically arranged on both sides of the lifting assembly 1 respectively. Each group of link rods includes a driving rod, a driven rod 33 and a clamping jaw 34 which are connected in sequence. When the lifting assembly 1 operates, the driving rod is touched, and the two clamping jaws 34 approach each other to close and press the product; when the lifting assembly 1 does not operate, the driving rod is not touched, and the two clamping jaws 34 are opened.
[0040] Further, referring to Figure 8 As shown, the driving rod includes a first driving rod 31 and a second driving rod 32. The first driving rod 31 extends in the vertical direction. One end in its extending direction is connected to the lifting platform 12, and the other end in its extending direction is connected to the connection end 3201 of the second driving rod 32. The second driving rod 32 includes a connection end 3201 and a fixed end 3202 located outside the connection end 3201. The fixed end 3202 is fixed to the mounting seat 14 of the lifting assembly 1; when the driving rod is touched, the connection end 3201 can rotate around the fixed end 3202.
[0041] Subsequently, when the driving rod is not touched, the second driving rod 32 is inclined, and the height of the connection end 3201 is lower than that of the fixed end 3202; when the driving rod is touched, the second driving rod 32 can rotate until the pressing member 6 presses the product. At this time, the height of the connection end 3201 is flush with that of the fixed end 3202.
[0042] It should be noted that in the preferred embodiment of the present utility model, one end of the second active rod 32 is set as a fixed end 3202 to connect the jacking assembly 1, the other end of the second active rod 32 is connected to the driven rod 33, and the connection end 3201 of the second active rod 32 for connecting the first active rod 31 is located in the middle of its extension direction. In the area other than the fixed end 3202 and the end for connecting the driven rod 33, preferably, the connection end 3201 is located at the midpoint of the extension direction of the second active rod 32, so that the connection end 3201 and the fixed end 3202 can fix the second active rod 32. That is to say, when the jacking height of the jacking assembly 1 is certain, the pulling height of the first active rod 31 is determined, and the connection end 3201 and the fixed end 3202 can fix the position of the second active rod 32, thereby fixing the positions of the driven rod 33 and the clamping jaw 34, avoiding over-displacement, and improving the reliability and stability of the device.
[0043] Further, referring to Figure 8 As shown, one end of the driven rod 33 is connected to the second active rod 32, and the end of the driven rod 33 away from the second active rod 32 is slidably connected to the sliding groove 3401 of the clamping jaw 34, and the sliding groove 3401 is set as an arc groove; when the active rod is not touched, one end of the driven rod 33 is located at one end of the sliding groove 3401, and when pressing the product, it is located at the other end of the sliding groove 3401.
[0044] Further, referring to Figure 8 As shown, the clamping jaw 34 has a first bending part 3402 and a second bending part 3403. The first bending part 3402 is fixed by a fixing member 2301, and the fixing member 2301 is connected to the edge 23 of the streamline assembly 2. Both groups of clamping jaws 34 can rotate symmetrically around the first bending part 3402; there is an avoidance gap 3404 between the two groups of clamping jaws 34 for the carrier 4 and the product to pass through.
[0045] Continuing, referring to Figure 8 and Figure 9 As shown, a pressing member 6, a spring 61 and a sheet metal part 62 are fixed at the free end of the clamping jaw 34; the spring 61 is located inside the clamping jaw 34 and connects the pressing member 6. The pressing member 6 is located at the free end of the connecting rod and is on the side of the product away from the jacking platform 12 in the vertical direction. The pressing member 6 is configured to press the product in the vertical direction when the active rod is touched; the sheet metal part 62 is located at the end of the clamping jaw 34 for fixing the pressing member 6.
[0046] The working principle of the jacking and clamping mechanism of the present utility model is as follows:
[0047] Start the motor to drive the synchronous belt 22 synchronously, place the product to be processed on the top surface of the carrier 4 and complete the assembly; the carrier 4 and the product are placed on one side of the synchronous belt 22 and move with the synchronous belt 22 until the carrier 4 abuts against the limiting member 5 and is stopped by limiting at the lifting and clamping position.
[0048] Refer to Figures 1 to 3 As shown, at this time, neither the lifting assembly 1 nor the clamping assembly 3 performs an action, the driving rod is not triggered, and one end of the driven rod 33 connecting the jaw 34 is located at one end of the chute 3401 away from the pressing member 6. The two jaws 34 are opened, and the avoidance gap 3404 can accommodate the carrier 4 and the product.
[0049] The driving part 11 acts, the lifting platform 12 is lifted, the gap between the bottom surface of the lifting platform 12 and the carrier 4 gradually decreases until the positioning pin 13 penetrates into the positioning hole 43 of the carrier 4, and the lifting platform 12 abuts against the carrier 4 and the product to realize the lifting action; the slide rail 15 acts synchronously with the driving part 11 to stably support the lifting platform 12.
[0050] During the lifting action, the first driving rod 31 is pulled up with the lifting platform 12, the second driving rod 32 rotates horizontally around the fixed end 3202, the driven rod 33 is driven to expand away from the lifting assembly 1, and one end of the driven rod 33 connecting the jaw 34 slides in the chute 3401 and slides to one end close to the pressing member 6, pushing the end of the jaw 34 away from the pressing member 6 to rotate outwards. Since the first bending part 3402 of the jaw 34 is fixed by the fixing member 2301, the jaw 34 rotates around the fixing member 2301, and the ends of the jaw 34 provided with the pressing member 6 approach and close to each other. Since the jaw 34 is bent again at the second bending part 3403, refer to Figures 4 to 6 As shown, at this time, the pressing member 6 is disposed opposite to the product in the vertical direction, the spring 61 in the jaw 34 deforms, compensating for the gap between the pressing member 6 and the product, so that the pressing member 6 presses the product; the product clamping function is realized while lifting.
[0051] When the driving part 11 drives the lifting platform 12 to descend, the clamping assembly 3 resets, the jaws 34 open, and the avoidance gap 3404 can allow the product and the carrier 4 to pass through again. The lifting and clamping mechanism of the present utility model can perform the lifting action and the clamping action simultaneously, and the carrier 4 and the product can pass freely in the streamline direction immediately before and after the action, without setting the waiting time for avoiding the clamping action stroke; compared with two independent processes, the processing time is greatly shortened.
[0052] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model.
