Description

Technical Field

[0001] This utility model relates to the field of fixed equipment technology, and in particular to a non-powered positioning and clamping device. Background Technology

[0002] When conveying or using material frames or other carriers, positioning and clamping devices are often used to fix them in place to prevent them from shifting or tipping over. Chinese patent application number 202023294105.2 discloses an automatic opening and closing clamping and positioning device for a carrier, comprising a base plate. A top plate is fixedly mounted on the upper surface of the base plate via four first support rods. A fixing rod is fixedly mounted at the center of the upper surface of the top plate. A sleeve is connected to the wall of the fixing rod via a limiting mechanism. A mounting plate is fixedly mounted at the upper end of the sleeve. A U-shaped plate is fixedly mounted on the upper surface of the mounting plate. A bidirectional lead screw is installed inside the U-shaped plate. The two ends of the bidirectional lead screw are rotatably connected to the left and right side plates of the U-shaped plate via first bearings. Slider blocks are symmetrically threaded to the two ends of the bidirectional lead screw. First connecting rods are fixedly mounted on the upper surfaces of the two sliders. A strip-shaped opening is provided inside the upper side plate of the U-shaped plate. The patent document describes a method where a motor drives a bidirectional lead screw to rotate. The rotating bidirectional lead screw causes two clamping plates to move closer or further apart, thus clamping the material frame or other carriers to fix them in place. This requires a drive unit (motor) to move the two clamping plates closer or further apart. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a non-powered positioning and clamping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A non-powered positioning and clamping device includes a base plate, a support column mounted on the top surface of the base plate, a top plate mounted on the top of the support column and parallel to the base plate, a slide block slidably mounted on the top surface of the base plate, a push rod mounted on the outer side of the slide block and extending beyond one side of the base plate, two abutting rods mounted on both ends of the inner side of the slide block, two fixing blocks mounted on both sides of the bottom surface of the top plate, two translation blocks slidably connected to the bottom surface of the top plate, two connecting rods fixedly connected to the two translation blocks respectively, and two connecting rods respectively mounted on the two... The connecting rod has two positioning clamping plates at the top and a support platform installed in the middle of the top surface of the top plate. The two positioning clamping plates are arranged opposite each other, and the support platform is located between the two positioning clamping plates. Two fixing blocks, two translation blocks and two abutting rods are respectively arranged one-to-one. The end of the translation block near the abutting rod is provided with an abutting slope. The abutting rod abuts against the abutting slope. The translation block is elastically connected to the fixing block through an elastic element. Translation grooves are provided on both sides of the top plate. The connecting rod passes through the translation groove and can translate within the translation groove.

[0006] Furthermore, the abutting pressure rod is rotatably connected to an inner rotating block, which rolls and abuts against the abutting inclined surface.

[0007] Furthermore, the outer end of the push rod is rotatably connected to an outer rotating block.

[0008] Furthermore, a limiting sliding component is installed on the bottom surface of the base plate, and the slide block is slidably connected to the base plate via the limiting sliding component.

[0009] Furthermore, the limiting sliding assembly includes a guide rail mounted on the top surface of the base plate, a slider mounted on the bottom surface of the slide block and slidably connected to the guide rail, an inner limiting block disposed at the inner end of the guide rail, and an outer limiting block disposed at the outer end of the guide rail, with the slider located between the inner limiting block and the outer limiting block.

[0010] Furthermore, a synchronous linkage structure is provided between the bottom surface of the top plate and the top surface of the bottom plate. The synchronous linkage structure is connected to the two translation blocks respectively. The synchronous linkage structure is used to ensure that the two translation blocks move closer or further away from each other synchronously.

[0011] Furthermore, the synchronous linkage structure includes a central shaft installed between the top plate and the bottom plate, a rotating plate rotatably sleeved outside the central shaft, two arc-shaped linkage grooves centrally symmetrically arranged at both ends of the rotating plate, and two linkage rods respectively installed on the bottom surface of the two translation blocks. The two linkage rods are respectively arranged in a one-to-one correspondence with the two arc-shaped linkage grooves, and the linkage rods extend into the arc-shaped linkage grooves and abut against the inner wall of the arc-shaped linkage grooves.

[0012] Furthermore, the linkage rod is rotatably connected to a linkage rotating block, which rolls against the inner wall of the arc-shaped linkage groove.

[0013] Furthermore, the positioning clamping plate includes a U-shaped plate installed at the top of the connecting rod and a pressure plate installed on the top surface of the U-shaped plate, the U-shaped plate and the pressure plate forming a positioning clamping cavity.

[0014] Furthermore, the non-powered positioning and clamping device also includes a conveyor and a docking bracket. The docking bracket is provided with a docking cavity and a support arm located above the docking cavity. The base plate is installed on the top of the conveyor. The docking cavity is used to accommodate the conveyor. A baffle is provided in the middle and rear part of the support arm or the top of the docking bracket. The baffle extends into the docking cavity and is used to abut against the push rod.

[0015] The beneficial effects of this utility model are as follows: In practical applications, initially, the support platform supports the bottom surface of the material frame to support it. The material frame is located between two positioning clamping plates. At this time, the elastic element is in an extended state. Under the elastic force of the elastic element, the distance between the two translation blocks decreases, thus reducing the distance between the two positioning clamping plates. When it is necessary to position and clamp the material frame, an inward pushing force is applied to the push rod, causing the push rod, along with the slide and the two abutting pressure rods, to move inward. The inwardly moving abutting pressure rods will compress the abutting inclined surface and have relative displacement with it, causing the translation blocks to compress the elastic element. This increases the distance between the two translation blocks, which in turn increases the distance between the two positioning clamping plates. The material frame can then be placed on the support platform, which supports the frame, positioning it between the two positioning clamping plates. Releasing the push rod causes the two translation blocks to move closer together under the rebound force of the elastic element. This brings the two positioning clamping plates closer together and positions and clamps the bottom of the material frame. During this process, the contact slope of the translation blocks pushes the contact pressure rod, causing the contact pressure rod, along with the slide and push rod, to move outward and reset. This invention enables the positioning and clamping of the material frame, improving its positional accuracy and stability. Furthermore, it eliminates the need for a drive unit, allowing the two positioning clamping plates to move closer or further apart, thus reducing manufacturing costs. Attached Figure Description

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figures 1 to 4 As shown, the present invention provides a non-powered positioning and clamping device, which includes a base plate 1, a support column 2 mounted on the top surface of the base plate 1, a top plate 3 mounted on the top of the support column 2 and parallel to and spaced apart from the base plate 1, a slide block 4 slidably mounted on the top surface of the base plate 1, a push rod 5 mounted on the outer side of the slide block 4 and extending beyond one side of the base plate 1, two abutting pressure rods 6 symmetrically mounted on both ends of the inner side of the slide block 4, two fixing blocks 7 mounted on both sides of the bottom surface of the top plate 3, two translation blocks 8 slidably connected to the bottom surface of the top plate 3, two connecting rods 9 fixedly connected to the two translation blocks 8 respectively, and two connecting rods 9 respectively mounted on the two... The top of the connecting rod 9 has two positioning clamping plates 10 and a support platform 11 installed in the middle of the top surface of the top plate 3. The two positioning clamping plates 10 are arranged opposite each other, and the support platform 11 is located between the two positioning clamping plates 10. Two fixing blocks 7, two translation blocks 8 and two abutting rods 6 are respectively arranged one-to-one. The end of the translation block 8 near the abutting rod 6 is provided with an abutting slope 12. The abutting rod 6 abuts against the abutting slope 12. The translation block 8 is elastically connected to the fixing block 7 through the elastic element 13. Both sides of the top plate 3 are provided with translation grooves 14. The connecting rod 9 passes through the translation grooves 14 and can translate within the translation grooves 14.

[0024] In practical applications, initially, the support platform 11 supports the bottom surface of the material frame 36 to support it. The material frame 36 is located between the two positioning clamping plates 10. At this time, the elastic element 13 is in an extended state. Under the elastic force of the elastic element 13, the distance between the two translation blocks 8 decreases, thus reducing the distance between the two positioning clamping plates 10. When it is necessary to position and clamp the material frame 36, an inward pushing force is applied to the push rod 5, causing the push rod 5, along with the slide block 4 and the two abutting pressure rods 6, to move inward. The inwardly moving abutting pressure rods 6 will compress the abutting inclined surface 12 and cause relative displacement with the abutting inclined surface 12, causing the translation block 8 to compress the elastic element 13, thereby making The distance between the two translation blocks 8 increases, which in turn increases the distance between the two positioning clamping plates 10. At this point, the material frame 36 can be placed on the support platform 11, which supports the material frame 36, and the material frame 36 is located between the two positioning clamping plates 10. Then, the pushing force on the push rod 5 is released, causing the two translation blocks 8 to move closer to each other under the action of the elastic force of the elastic element 13. This causes the two positioning clamping plates 10 to move closer to each other and position and clamp the bottom of the material frame 36. During the process of the two translation blocks 8 moving closer to each other, the abutting inclined surface 12 of the translation blocks 8 pushes the abutting pressure rod 6, causing the abutting pressure rod 6, along with the slide 4 and the push rod 5, to move outward and reset. This utility model can realize the positioning and clamping of the material frame 36, improve the positional accuracy and stability of the material frame 36, and can realize the two positioning clamping plates 10 moving closer or further apart without the need for a drive unit, thus reducing the manufacturing cost.

[0025] In this embodiment, the abutting rod 6 is rotatably connected to an inner rotating block 15, which rolls against the abutting inclined surface 12. Specifically, the inner rotating block 15 is a wheel, a ball, or a bearing, etc. By rolling against the abutting inclined surface 12, frictional resistance and wear are reduced. Even if the inner rotating block 15 wears out, only the inner rotating block 15 needs to be replaced, making maintenance convenient and cost-effective.

[0026] In this embodiment, an outer rotating block 16 is rotatably connected to the outer end of the push rod 5. Specifically, the outer rotating block 16 is a wheel, ball, or bearing, etc., and the rotation axis of the outer rotating block 16 is horizontally set. By having the outer rotating block 16 abut against the baffle 35 or the external structure, even if the outer rotating block 16 is worn, only the outer rotating block 16 needs to be replaced, making maintenance convenient and cost-effective. Furthermore, when the push rod 5 rises and falls, the outer rotating block 16 can roll against the external structure, reducing frictional resistance and wear.

[0027] In this embodiment, a limiting sliding component 17 is installed on the bottom surface of the base plate 1, and the slide block 4 is slidably connected to the base plate 1 via the limiting sliding component 17. When the slide block 4 slides relative to the base plate 1, the limiting sliding component 17 not only plays a guiding role, but also limits the reciprocating stroke of the slide block 4, thereby improving the movement stability of the slide block 4.

[0028] In this embodiment, the limiting sliding assembly 17 includes a guide rail 18 mounted on the top surface of the base plate 1, a slider 19 mounted on the bottom surface of the slide block 4 and slidably connected to the guide rail 18, an inner limiting block 20 disposed at the inner end of the guide rail 18, and an outer limiting block 21 disposed at the outer end of the guide rail 18. The slider 19 is located between the inner limiting block 20 and the outer limiting block 21. Specifically, there are two sets of limiting sliding assemblies 17, and the push rod 5 is located between the two sets of limiting sliding assemblies 17. When the slide block 4 moves, the slider 19 slides in conjunction with the guide rail 18, which improves the movement stability of the slide block 4. The inner limiting block 20 can block the slide block 4 from moving inward to its extreme position, and the outer limiting block 21 can block the slide block 4 from moving outward to its extreme position, so as to ensure that the slide block 4 can move within a preset stroke.

[0029] In this embodiment, a synchronous linkage structure 22 is provided between the bottom surface of the top plate 3 and the top surface of the bottom plate 1. The synchronous linkage structure 22 is connected to two translation blocks 8 for transmission. The synchronous linkage structure 22 is used to ensure that the two translation blocks 8 move synchronously closer to or further away from each other. Specifically, the synchronous linkage structure 22 includes a central shaft 23 installed between the top plate 3 and the bottom plate 1, a rotating plate 24 rotatably sleeved outside the central shaft 23, two arc-shaped linkage grooves 25 centrally symmetrically arranged at both ends of the rotating plate 24, and two linkage rods 26 respectively installed on the bottom surfaces of the two translation blocks 8. The two linkage rods 26 are respectively arranged in a one-to-one correspondence with the two arc-shaped linkage grooves 25, and the linkage rods 26 extend into the arc-shaped linkage grooves 25 and abut against the inner wall of the arc-shaped linkage grooves 25. By setting the synchronous linkage structure 22, not only is it ensured that the two translation blocks 8 move synchronously closer to or further away from each other, but it also avoids the phenomenon of jamming or unsmooth movement of the translation blocks 8 due to uneven force (single-end / local force of the translation block 8).

[0030] In this embodiment, the linkage rod 26 is rotatably connected to a linkage rotating block 27, which rolls against the inner wall of the arc-shaped linkage groove 25. Specifically, the linkage rotating block 27 is a wheel, a ball, or a bearing, etc. As the linkage rod 26 follows the translation block 8, the linkage rod 26 drives the linkage rotating block 27 to move synchronously. The moving linkage rotating block 27 rolls against the inner wall of the arc-shaped linkage groove 25 and can abut against the rotating plate 24 to make adaptive rotation.

[0031] In this embodiment, the positioning clamping plate 10 includes a U-shaped plate 28 mounted on the top of the connecting rod 9 and a pressure plate 29 mounted on the top surface of the U-shaped plate 28. The U-shaped plate 28 and the pressure plate 29 form a positioning clamping cavity 30. When the two positioning clamping plates 10 clamp the bottom of the material frame 36, the bottom of the material frame 36 is located in the positioning clamping cavity 30. The U-shaped plate 28 positions and clamps the bottom of the material frame 36, and the pressure plate 29 presses down on the bottom of the material frame 36, so as to stably position, clamp, and press the material frame 36 onto the support platform 11.

[0032] Specifically, a fixing hole is recessed on one side of the fixed block 7 and the translation block 8 that are close to each other, and the end of the elastic element 13 is inserted into the fixing hole. The elastic element 13 is a spring. This structural design facilitates the assembly of the spring and improves the positional accuracy and working stability of the spring.

[0033] Specifically, the non-powered positioning and clamping device also includes a conveyor 31 and a docking bracket 32. The docking bracket 32 ​​is provided with a docking cavity 33 and a support arm 34 located above the docking cavity 33. The base plate 1 is installed on the top of the conveyor 31. The docking cavity 33 is used to accommodate the conveyor 31. A baffle 35 is provided in the middle and rear part of the support arm 34 or the top of the docking bracket 32. The baffle 35 extends into the docking cavity 33 and is used to abut against the push rod 5. There are two support arms 34. The support platform 11 can move between the two support arms 34. The conveyor 31 can be a lifting AGV trolley or a lifting pusher.

[0034] In practical applications, initially, the support platform 11 supports the bottom surface of the material frame 36 to support it. The material frame 36 is located between the two positioning clamping plates 10. At this time, the elastic element 13 is in an extended state. Under the elastic force of the elastic element 13, the distance between the two translation blocks 8 decreases, which in turn decreases the distance between the two positioning clamping plates 10 and positions and clamps the material frame 36. When the conveyor 31 transports the positioned and clamped material frame 36 to the docking bracket 32, the conveyor 31 enters the docking cavity 33, causing the material frame 36 to move above the support arm 34. Then, as the conveyor 31 continues to move into the docking cavity 33, the push rod 5 will abut against the baffle 35. The baffle 35 squeezes the push rod 5, causing the push rod 5 to move towards the contact slope 12 (inward) under the squeezing force. The moving push rod 5, together with the slide 4 and the two contact pressure rods 6, moves synchronously, causing the contact pressure rods 6 to squeeze the contact slope 12. 2. The two translation blocks 8 move away from each other and move relative to the contacting inclined surface 12. This causes the two translation blocks 8 to move away from each other, which in turn causes the two positioning clamping plates 10 to move away from each other and release the material frame 36. Finally, the conveyor 31 drives the bottom plate 1 to descend, causing the support platform 11 and push rod 5 to descend until the support arm 34 contacts the bottom surface of the material frame 36 and supports the material frame 36. The support platform 11 separates from the material frame 36, and the push rod 5 separates from the baffle 35. At this time, the conveyor 31 can move out of the docking cavity 33. Since the push rod 5 is not subjected to the squeezing force of the baffle 35, the translation block 8 resets under the action of the elastic force of the elastic element 13, which reduces the distance between the two translation blocks 8. During the reset process of the translation block 8, the contacting inclined surface 12 of the translation block 8 pushes the contacting pressure rod 6, causing the contacting pressure rod 6, along with the slide 4 and the push rod 5, to move outward, which causes the push rod 5 to move outward and reset. This structural design improves the stability of the conveying frame 36 by positioning and clamping the frame 36 with two positioning clamping plates 10 during the conveying process, preventing the frame 36 from tipping over during conveying. When the conveying vehicle 31 delivers the frame 36 to the designated position, the two positioning clamping plates 10 can release the frame 36 simply by the push rod 5 contacting the baffle 35 or the external structure, without the need for additional driving force (drive unit) to push the push rod 5.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
