Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to a mechanical template clamping device. Background Technology

[0002] Construction engineering encompasses all technical work related to the planning, surveying, design, construction, and completion of new buildings, renovations, or expansions of buildings and ancillary structures and facilities. It includes the finished engineering entity and the installation of associated lines, pipelines, and equipment. It also refers to the construction of various houses and buildings, also known as building workload. This portion of the investment requires labor and materials and can only be realized through construction activities. In the production of construction machinery, some structural components need to be produced using formwork casting, which necessitates the use of clamping equipment during formwork production.

[0003] The template clamping device for construction machinery described in publication number CN217602115U includes a housing. A second fixing groove is provided at the upper end of the front of the housing, and a first fixing groove is provided at the middle of the lower surface of the housing. A motor box is fixedly connected to the middle of the upper surface of the housing. A servo motor is fixedly connected to the middle of the bottom of the inner cavity of the motor box. The output end of the servo motor passes through the middle of the top of the second fixing groove and is fixedly connected to a first gear. A screw is movably connected to the middle of the left side of the second fixing groove. A second gear is fixedly connected to the right side of the front of the screw. The second gear meshes with the first gear. A clamping arm is fixedly connected to the middle of the lower surface of the slider.

[0004] Based on the above technical features, the problem is that in the prior art, the two clamping arms are parallel to each other when clamping the mechanical template, and the clamping forces are collinear and set in opposite directions. Therefore, when the suction cup's adsorption force on the mechanical template is insufficient, the mechanical template relies on the static friction force with the two clamping arms to remain stationary. Under the action of the mechanical template's gravity, it is very easy for the mechanical template to detach from the two clamping arms and damage the mechanical template.

[0005] Therefore, it is necessary to solve the above problems by using a mechanical template clamping device. Summary of the Invention

[0006] The purpose of this invention is to provide a mechanical template clamping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A mechanical template clamping device, comprising a housing, wherein two symmetrically distributed support shafts are fixedly arranged inside the housing, and each support shaft is rotatably mounted with a clamping plate and a connecting rod; the two clamping plates and the two connecting rods are symmetrical about the center of symmetry of the two support shafts; the two connecting rods correspond one-to-one with the two clamping plates, and each connecting rod is fixedly connected to the corresponding clamping plate, and the two clamping plates rotate toward each other to form an inverted V-shaped clamping structure; a first driving mechanism is installed inside the housing, and the output end of the first driving mechanism is driven to connect to a moving plate, and two symmetrically distributed transmission rods are hinged to the moving plate; the two transmission rods correspond one-to-one with the two connecting rods, and the two transmission rods are hinged to the corresponding connecting rods; a second driving mechanism is installed inside the housing, and the output end of the second driving mechanism is driven to connect to a connecting plate for driving the connecting plate to move up and down; a plurality of suction cups are fixedly arranged on the connecting plate, and the suction cups are located between the two clamping plates.

[0008] Preferably, the first drive mechanism includes two synchronously operating electric push rods, which are fixedly installed inside the housing. The output ends of both electric push rods are fixedly connected to the moving plate to push the moving plate to move.

[0010] Preferably, the first limiting member includes a first slider and a first fixing plate. The first slider is fixedly connected to the internal threaded cylinder, and the first fixing plate is fixedly connected to the housing. A first sliding groove is formed on the first fixing plate, and the first slider is inserted into the first sliding groove and slides in a limiting engagement with the first sliding groove.

[0011] Preferably, air cushions are fixedly installed at the ends of the two clamping plates that are away from the connected support shaft and close to each other.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] This utility model provides, for example Figures 1 to 3 The mechanical template clamping device shown includes a housing 1. (As illustrated...) Figure 1 As shown, two horizontal support shafts 7 are welded inside the housing 1. The two support shafts 7 are symmetrically distributed, one on the left and one on the right. Clamping plates 5 are rotatably connected to both support shafts 7. Both clamping plates 5 are straight plates and are symmetrically distributed, one on the left and one on the right, about the center of symmetry of the two support shafts 7. The two clamping plates 5 pass downwards through the housing 1 and rotate close together to form an inverted V-shaped clamping structure for clamping the mechanical template.

[0028] Air cushions 6 are fixedly mounted on the ends of the two clamping plates 5 away from the connected support shaft 7, with each air cushion 6 located on the end face of the clamping plate 5 closest to the other clamping plate 5. When the two clamping plates 5 clamp the mechanical template, the contact area between the air cushion 6 and the mechanical template is large, thereby increasing the static friction force between the clamping plate 5 and the mechanical template. At the same time, the soft connection between the air cushion 6 and the mechanical template can better protect the mechanical template from damage.

[0029] Both support shafts 7 are rotatably connected to connecting rods 22, which are symmetrically distributed in an inverted V-shape about the center of symmetry of the two support shafts 7. Each connecting rod 22 corresponds to one of the two clamping plates 5, and each connecting rod 22 is fixedly connected to the corresponding clamping plate (5).

[0030] A first drive mechanism is fixedly installed inside the housing 1. The first drive mechanism includes two synchronously operating electric push rods 2, which are bolted to the housing 1. The two electric push rods 2 are located between two support shafts 7 and are symmetrically distributed, one on the left and one on the right. The output shafts of the two electric push rods 2 slide vertically upwards through the housing 1 and are fixedly connected to the same moving plate 3. Two transmission rods 4 are hinged to the moving plate 3. The two transmission rods 4 are symmetrically distributed, one on the left and one on the right. One of the transmission rods 4 is hinged to the left side of the moving plate 3, and the other is hinged to the right side. The two transmission rods 4 correspond to two connecting rods 22, and each transmission rod 4 is hinged to its corresponding connecting rod 22. This mechanism is used to drive the rotation of the two clamping plates 5.

[0031] A second drive mechanism, including a motor 8, is fixedly mounted inside the housing 1. The motor 8 is bolted to the housing 1. The output shaft of the motor 8 rotates vertically downwards through the housing 1. Figure 3 As shown, the output shaft of motor 8 is coaxially and fixedly connected to the first threaded rod 9, and the first threaded rod 9 is coaxially and threadedly connected to the internal threaded cylinder 10. The bottom of the internal threaded cylinder 10 is fixedly connected to a horizontal connecting plate 11, which is located between two clamping plates 5. Several suction cups 12 are fixedly mounted on the bottom of the connecting plate 11 for adsorbing mechanical templates.

[0032] A first limiting component is installed between the housing 1 and the internally threaded cylinder 10. The first limiting component includes a first slider 13 and a first fixing plate 14. The first slider 13 is fixedly connected to the internally threaded cylinder 10, and the first fixing plate 14 is welded and fixed to the bottom of the housing 1. A first groove 15 is cut out on the first fixing plate 14, and the first slider 13 is inserted into the first groove 15 and slides in a limiting engagement with the first groove 15. This ensures that the internally threaded cylinder 10 does not rotate when it moves up and down.

[0033] Working principle of Example 1:

[0034] In use, place the mechanical template between the two clamping plates 5. Then start the motor 8. The output shaft of the motor 8 rotates and drives the first threaded rod 9 to rotate. The first threaded rod 9 pushes the internal threaded cylinder 10 downward. The internal threaded cylinder 10 drives the connecting plate 11 downward. The connecting plate 11 drives all the suction cups 12 downward. After all the suction cups 12 have contacted and adhered to the mechanical template, turn off the motor 8.

[0035] During the downward movement of the internal threaded cylinder 10, the internal threaded cylinder 10 drives the first slider 13 to slide down along the first groove 15 of the first fixed plate 14, so that the internal threaded cylinder 10 will not rotate with the first threaded rod 9 due to friction.

[0036] Then, two first electric push rods 2 are activated simultaneously. The output shafts of the two first electric push rods 2 extend upward and drive the moving plate 3 to move upward. The moving plate 3 drives the two transmission rods 4 to move upward and push the two transmission rods 4 to rotate. The two transmission rods 4 drive the two connecting rods 22 to rotate around their respective support shafts 7. The two connecting rods 22 drive the two clamping plates 5 to rotate around their respective support shafts 7. The two clamping plates 5 rotate and approach to form an inverted V-shaped clamping mechanism and clamp the mechanical template. During this process, the two air cushions 6 contact the mechanical template and form a clamp. When the suction force of the suction cup 12 is insufficient, the inverted V-shaped clamping structure formed by the rotation of the two clamping plates 5 provides support for the mechanical template not only through static friction but also through the plate body, ensuring that the mechanical template is not easily detached from the two clamping plates 5.

[0037] Example 2

[0038] like Figures 4 to 5 The mechanical template clamping device shown in this embodiment differs from Embodiment 1 in that the first drive mechanism includes a second threaded rod 17. For example... Figure 5 As shown, the second threaded rod 17 is located between the two support shafts 7. The second threaded rod 17 rotates vertically upward from inside the housing 1 and is rotatably connected to the housing 1. The top of the second threaded rod 17 is threadedly connected to the movable plate 3, which is used to push the movable plate 3 to move up and down.

[0039] A second limiting component is installed between the movable plate 3 and the housing 1. The second limiting component includes two second fixing plates 19 and two second sliders 20. The two second fixing plates 19 are both vertically arranged and welded to the top of the housing 1, and are symmetrically distributed, one on the left and one on the right. The two second sliders 20 are also symmetrically distributed, one on the left and one on the right, and are correspondingly welded and fixed to the left and right ends of the movable plate 3.

[0040] The two second fixed plates 19 are each cut with a second groove 21. The two second sliders 20 correspond one-to-one with the two second grooves 21. Each second slider 20 is inserted into the corresponding second groove 21 and is limited to sliding cooperation with the corresponding second groove 21.

[0041] The second threaded rod 17 is linked to the output shaft of the motor 8 via a linkage assembly, which includes a first gear 16 and a second gear 18. The first gear 16 is sleeved on the output shaft of the motor 8, and the second gear 18 is coaxially and fixedly connected to the second threaded rod 17. The first gear 16 and the second gear 18 mesh with each other. This linkage assembly is used to drive the second threaded rod 17 to rotate.

[0042] Working principle of Example 2:

[0043] The difference between this working principle and the working principle of Embodiment 1 is that the rotation of the output shaft of the motor 8 will drive the first gear 16 to rotate, the first gear 16 will drive the second gear 18 to rotate, the second gear 18 will drive the second threaded rod 17 to rotate, and the second threaded rod 17 will push the moving plate 3 to move upward.

[0044] During the upward movement of the movable plate 3, the two second sliders 20 slide along the second grooves 21 on the corresponding second fixed plate 19, and the movable plate 3 will not rotate with the second threaded rod 17 under the action of friction.

[0045] The other working principles are the same as in Example 1, so they will not be described in detail here.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
