Description

Technical Field

[0001] This utility model belongs to the field of material clamping and positioning technology, specifically relating to a portable clamping device. Background Technology

[0002] In coal mine washing and processing, the maintenance personnel of the plant's machine repair team are responsible for the inspection and maintenance of all equipment within the scope of the project department's business. The equipment on site is numerous and complex. When faced with different equipment failure situations, it is often necessary to cut and manufacture spare parts and repair parts according to the actual needs on site, as well as disassemble damaged parts. In the material handling process, since it is an on-site operation, the fixing of materials or parts is traditionally done by foot pedals. This type of fixing method has significant differences in fixing effect for different structural materials (such as square tubes, round tubes, ball heads, etc.), especially when disassembling bolts on damaged parts.

[0003] Therefore, we designed a portable clamping device that can clamp and fix different types of materials. Utility Model Content

[0004] The purpose of this invention is to provide a portable clamping device to solve the aforementioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable clamping device includes a base, on one of the top ends of which a clamping operating mechanism is mounted via a mounting seat, and a pressing mechanism for clamping materials is mounted at the front end of the clamping operating mechanism.

[0007] The clamping mechanism adopts a quick-clamp structure design, utilizing the dead-point positioning principle of the quick-clamp to ultimately achieve stable clamping and fixing of materials. Specifically, the clamping mechanism consists of an operating handle, a lower pressure arm, and a connecting plate. The operating handle, used to operate the entire device for material clamping, comprises a locking part, a push-pull arm, and a handle. The bottom end of the locking part is hinged to the top of the rear end of the mounting base. The lower pressure arm adopts a T-shaped structure design, with its bottom hinged to the top of the front end of the mounting base. The rear end of the lower pressure arm is connected to the middle of the locking part of the operating handle via a connecting plate. The connecting plate is hinged to both the lower pressure arm and the locking part via pins.

[0008] Furthermore, to facilitate the clamping effect of the lower pressure arm on the material, the pressing mechanism consists of a threaded sleeve, a threaded rod, a positioning component, and a material clamping component. The threaded sleeve is vertically welded to the front end of the lower pressure arm, the threaded rod is screwed into the threaded sleeve, the positioning component is threaded onto the bottom end of the threaded rod, and the material clamping component is installed at the bottom end of the threaded rod through the positioning component. The threaded rod consists of a screw and a screw cap, the screw cap is fixed to the top of the screw, the screw is located inside the threaded sleeve and is threadedly assembled with the threaded sleeve, and the height of the material clamping component can be adjusted by screwing the threaded rod to accommodate materials of different thicknesses or sizes.

[0009] Furthermore, the screw also has an integrally formed central positioning perforation for installing a material clamping component.

[0010] Furthermore, to facilitate the operator in switching the angle of the material clamping component according to the material type, thereby effectively positioning and clamping the material, the positioning component includes a nut threadedly assembled with the bottom end of the screw. A circular positioning disc is horizontally welded to the bottom end of the nut, and several positioning grooves are provided at equal intervals around the circumference of the bottom of the positioning disc with the screw as the center. A guide sleeve is provided at the center of the positioning disc. At the same time, the material clamping component includes a circular base, a pressure plate integrally formed at the bottom of the base, and positioning teeth integrally formed on the top side of the base corresponding to the positioning grooves.

[0011] Meanwhile, in order to ensure that the angle of the pressure plate remains fixed at the bottom of the positioning component without external interference and to achieve automatic angle locking, a vertically set push rod is fixed at the center of the top of the base. The top of the push rod passes through the guide sleeve and enters the central positioning hole inside the screw, and finally slides through the screw cap to extend to the outside of the top of the screw. A positioning block that slides with the inner wall of the central positioning hole is fixedly installed on the outside of the rod body inside the central positioning hole. A spring is also fitted on the outside of the push rod between the bottom of the positioning block and the positioning plate.

[0012] Furthermore, in order to improve the adaptability of the device to different types of materials during compression, the cross-section of the pressure plate is designed with a V-shape, and both sides of the pressure plate are integrally formed with flat feet; at the same time, a spherical groove is integrally formed at the center of the inner side of the pressure plate.

[0013] Beneficial effects:

[0014] This utility model has a simple and portable structure and is easy to use. It utilizes the dead-point positioning principle of traditional quick clamps and a pressing mechanism to effectively clamp and fix materials. Moreover, the structural design of the pressing mechanism makes the device more stable than traditional on-site material fixing methods. It can effectively clamp square tubes, round tubes, and ball-shaped materials, and can clamp materials from different angles according to actual needs. It is extremely practical and provides convenience for on-site equipment maintenance and material unloading. Attached Figure Description

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0025] Example

[0026] To address the issue of insufficient stability in clamping different types of materials using traditional foot-operated clamping methods during on-site material handling and equipment parts disassembly in factory maintenance operations, we have designed a portable clamping device capable of clamping and securing various materials. The specific solution is as follows:

[0027] like Figure 1-3 As shown, this embodiment provides a portable clamping device, including a base 1. A clamping operation mechanism is mounted on one top end of the base 1 via a mounting seat 2, and a pressing mechanism is mounted on the front end of the clamping operation mechanism for clamping materials.

[0028] The clamping mechanism adopts a quick clamp structure design, utilizing the dead-point positioning principle of the quick clamp to ultimately achieve stable clamping and fixing of materials. The clamping mechanism is specifically composed of an operating handle 3, a lower pressure arm 4, and a connecting plate 5. The operating handle 3, which is used to operate the entire device to clamp materials, consists of a locking part 301, a push-pull arm 302, and a handle 303. The bottom end of the locking part 301 is hinged to the top of the tail end of the mounting base 2. The lower pressure arm 4 adopts a T-shaped structure design, and the bottom of the lower pressure arm 4 is hinged to the top of the front end of the mounting base 2. The tail end of the lower pressure arm 4 is connected to the middle of the locking part 301 of the operating handle 3 through the connecting plate 5. The connecting plate 5 is hinged to the lower pressure arm 4 and the locking part 301 through pins.

[0029] To achieve a clamping effect on the material in conjunction with the lower pressure arm 4, its pressing mechanism consists of a threaded sleeve 6, a threaded rod 7, a positioning component 8, and a material clamping component 9. The threaded sleeve 6 is vertically welded to the front end of the lower pressure arm 4, the threaded rod 7 is screwed into the threaded sleeve 6, the positioning component 8 is threaded onto the bottom end of the threaded rod 7, and the material clamping component 9 is installed at the bottom end of the threaded rod 7 via the positioning component 8. For example... Figure 6 As shown, the threaded rod 7 consists of a screw 701 and a screw cap 702. The screw cap 702 is fixed to the top of the screw 701. The screw 701 is located inside the threaded sleeve 6 and is threaded together with the threaded sleeve 6. The height of the material clamping assembly 9 can be adjusted by screwing the threaded rod 7 to accommodate materials of different thicknesses or sizes.

[0030] The screw 701 also has an integrally formed central positioning through hole 703 for installing the material clamping component 9.

[0031] To allow operators to easily switch the angle of the material clamping component 9 according to the material type, thereby effectively positioning and clamping the material, such as... Figure 7-8 As shown, its positioning component 8 includes a nut 801 threadedly assembled with the bottom end of the screw 701. A circular positioning disc 802 is horizontally welded to the bottom end of the nut 801. Several positioning grooves 804 are evenly spaced around the bottom of the positioning disc 802 with the screw 701 as the center. A guide sleeve 803 is located at the center of the positioning disc 802. Meanwhile, as shown... Figure 4-5 As shown, the material clamping assembly 9 includes a circular base 901, a pressure plate 902 integrally formed at the bottom of the base 901, and a positioning tooth 905 integrally formed at the top side of the base 901 corresponding to the positioning groove 804.

[0032] Meanwhile, in order to ensure that the angle of the pressure plate 902 remains fixed at the bottom of the positioning assembly 8 without external interference, thus achieving automatic angle locking, a vertically installed push rod 906 is fixed at the center of the top of the base 901. The top of the push rod 906 passes through the guide sleeve 803 and enters the central positioning hole 703 inside the screw 701, eventually sliding through the screw cap 702 and extending to the outer side of the top of the screw 701. A positioning block 907 is fixedly installed on the outside of the rod body inside the central positioning hole of the push rod 906, which slides with the inner wall of the central positioning hole. The bottom of the positioning block 907 is in contact with the positioning hole. A spring 908 is also fitted on the outside of the push rod 906 between the discs 802. In its natural state, the push rod 906, through the cooperation of the spring 908, the positioning block 907, and the positioning disc 802, always generates a pulling force towards the upper end of the screw 701, so that the positioning teeth 905 are always engaged with the positioning groove 804, thereby preventing the angle of the base 901 from changing. When it is necessary to adjust the angle of the pressure plate 902, simply press the push rod 906 from the top of the screw 701 to disengage the positioning teeth 905 from the positioning groove 804, and the angle of the pressure plate 902 can be adjusted to adapt to the clamping of different types of materials.

[0033] To improve the adaptability of the device to different types of materials during compression, the cross-section of the pressure plate 902 is designed with a V-shaped structure, and both sides of the pressure plate 902 are integrally formed with flat feet 903; at the same time, a spherical groove 904 is integrally formed at the center of the inner side of the pressure plate 902.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
