[0002] A clamping device is a device that holds and manipulates objects. It can clamp and release objects while performing certain actions. During the processing of construction engineering machinery formwork, it is often necessary to use a clamping device to clamp the formwork.

[0003] Some existing clamping devices used in the production of mechanical formwork have some shortcomings. For example, only the two sides of the formwork are clamped, which will cause uneven force on the top of the formwork. The tops of some thinner formworks will warp up, affecting the processing of the formwork. After searching, the patent with authorization announcement number CN220093872U discloses a clamping device for construction engineering mechanical formwork. The device can clamp the two sides and the top of the formwork to prevent the top from warping up, but the clamping parts of the device will cover most of the space on the top of the formwork, which will also affect the processing of the top area of ​​the formwork.

[0008] A receiving groove is provided at the bottom of the positioning block, and a sliding positioning mechanism is installed in the receiving groove. The sliding positioning mechanism includes a first pressure-sensitive sensor installed at the top of the receiving groove, and a pulley frame slidably arranged in the receiving groove, a compression spring is installed at the top of the pulley frame, a pulley is installed at the bottom of the pulley frame, and a controller is installed on one side of the fixed base plate.

[0009] Furthermore, the pulley frame is fixedly connected to one end of the bottom of the compression spring, and when the pulley frame is located at the bottom of the accommodating groove, there is a gap between the compression spring and the first pressure-sensitive sensor.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] For examples, please refer to the attached Figure 1-5 The template clamping device for construction engineering machinery comprises a fixed bottom plate 10, a slide groove 11 is arranged at the top center of the fixed bottom plate 10, a transverse clamping mechanism 20 is installed on the fixed bottom plate 10, and the transverse clamping mechanism 20 comprises two sliders 23 located in the slide groove 11, and a moving plate 30 is installed on the two sliders 23, and a supporting plate 32 is arranged at the bottom of the two moving plates 30 close to each other, and two lifting grooves 31 are arranged on the moving plate 30 at the top of the supporting plate 32;

[0028] The movable plate 30 is provided with a longitudinal clamping mechanism 40, which comprises two lifting screws 43 rotatably connected and arranged in two lifting grooves 31, two positioning blocks 41 horizontally slidably mounted on the two lifting screws 43, and a first motor 42 mounted on the top of the movable plate 30 and connected to the lifting screws 43, and the two lifting screws 43 are connected by a transmission belt;

[0029] A receiving groove 411 is provided at the bottom of the positioning block 41, and a sliding positioning mechanism 50 is installed in the receiving groove 411. The sliding positioning mechanism 50 includes a first pressure-sensitive sensor 54 installed at the top of the receiving groove 411, and a pulley frame 52 slidably arranged in the receiving groove 411, a compression spring 53 is installed at the top of the pulley frame 52, a pulley 51 is installed at the bottom of the pulley frame 52, and a controller 60 is installed on one side of the fixed base plate 10.

[0030] It should be noted that all electrical components of the device are electrically connected to the controller 60 .

[0031] For details, please refer to the attached Figure 5 , the pulley frame 52 and one end of the bottom of the compression spring 53 are fixedly connected, and when the pulley frame 52 is located at the bottom of the accommodating groove 411, there is a gap between the compression spring 53 and the first pressure-sensitive sensor 54;

[0032] In this embodiment, it should be noted that when the pulley frame 52 is located at the bottom of the accommodating groove 411 due to gravity, the compression spring 53 will not contact the first pressure-sensitive sensor 54 to prevent the first pressure-sensitive sensor 54 from being triggered incorrectly.

[0033] For details, please refer to the attached Figure 4 and attached Figure 5 , rolling shaft rollers 56 are rotatably connected to both sides of the pulley frame 52, and the rolling surface of the rolling shaft rollers 56 is in contact with the inner wall of the accommodating groove 411;

[0034] In this embodiment, it should be noted that the rolling shaft roller 56 can help the pulley frame 52 to be better reset due to gravity, thereby preventing the pulley frame 52 from being stuck in the middle of the accommodating groove 411, causing the first pressure-sensitive sensor 54 to be continuously triggered.

[0035] For details, please refer to the attached Figure 4 The sliding positioning mechanism 50 also includes a second pressure-sensitive sensor 55 embedded in the front side of the bottom of the positioning block 41;

[0036] In this embodiment, it should be noted that when the pulley 51 is completely retracted into the accommodating groove 411, the positioning block 41 continues to descend, and the template will contact the second pressure-sensitive sensor 55. When the second pressure-sensitive sensor 55 senses sufficient pressure, it means that the positioning block 41 has fixed the template.

[0037] Furthermore, rubber pads 412 are installed on both sides of the bottom surface of the positioning block 41;

[0038] In this embodiment, it should be noted that the rubber pad 412 can increase the friction resistance to better fix the template.

[0039] For details, please refer to the attached Figure 2 The lateral clamping mechanism 20 further includes a bidirectional screw rod 22 rotatably connected to the slide slot 11, and a second motor 21 installed on one side of the bidirectional screw rod 22, and the two sliders 23 are symmetrically slidably installed on the bidirectional screw rod 22;

[0040] In this embodiment, it should be noted that the operation of the second motor 21 can realize the rotation of the bidirectional screw rod 22, thereby making the two sliders 23 at symmetrical positions approach each other, and cooperate with other mechanisms to complete the fixed clamping of the template.

[0041] For details, please refer to the attached Figure 2 and attached Figure 3 , arc-shaped protrusions 33 are provided on both sides of the bottom of the movable plate 30, and two arc-shaped slide rail grooves 12 adapted to the arc-shaped protrusions 33 are provided on the top of the fixed bottom plate 10;

[0042] In this embodiment, it should be noted that when the moving plate 30 moves, the arc-shaped protrusion 33 will slide inside the arc-shaped slide rail groove 12, so that the movement of the moving plate 30 is more stable.

[0043] The specific operation mode of the utility model is as follows:

[0044] First, according to the length of the template to be clamped, the distance between the two moving plates 30 is adjusted. The operation of the second motor 21 can realize the rotation of the bidirectional screw rod 22, so that the two sliders 23 in symmetrical positions are close to each other. Then, the template is placed on the top of the support plate 32 of the two moving plates 30 and located between the two positioning blocks 41. Then, the first motor 42 is started by the controller 60, and the transmission wheel belt is used to realize the synchronous rotation of the two lifting screw rods 43, so that the positioning block 41 is close to the template. The bottom of the pulley 51 first contacts the template. When the positioning block 41 continues to descend, the pulley 51 and the pulley frame 52 will The two movable plates 30 slowly move away from each other, and the positioning block 41 continues to descend until the pulley 51 is completely retracted into the accommodating groove 411. At this time, the positioning block 41 continues to descend, and the template will contact the second pressure-sensitive sensor 55. As the two movable plates 30 slowly move away from each other, after the positioning block 41 contacts the template, the template is given an outward pulling force as a whole. When the second pressure-sensitive sensor 55 senses enough pressure, it means that the positioning block 41 has fixed the template, and the device stops operating.

[0045] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
