Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary tools for parts processing, and specifically relates to a handheld cutting machine operating frame. 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, and they face repair and maintenance tasks for different equipment and chutes every day. During the operation, it is often necessary to prepare repair materials according to the damage of the equipment on site and the wear of the chutes. The size of the repair materials directly affects the time and quality of the chutes and equipment being repaired. In the process of preparing repair materials, the handheld angle grinder is a commonly used tool for on-site material cutting due to its good portability. However, because it is used directly by hand, the stability and reliability of the cutting machine during material cutting are directly proportional to the operator's technical ability (skill level). Skilled operators can cut the material to the perfect size, while less skilled operators can cut the material to a much larger size, which makes on-site welding and repair difficult.

[0003] Therefore, we propose a handheld cutting machine operating frame. Utility Model Content

[0004] The purpose of this invention is to provide a handheld cutting machine operating frame 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 handheld cutting machine operating frame includes a base; an operating lever is rotatably mounted on one end of the top of the base via a hinge seat, and a quick-release clamp device is installed on the operating lever to fix the handheld electric cutting machine. The handheld electric cutting machine is detachably mounted on one side of the operating lever using the quick-release clamp device, making the entire operation process quick and convenient.

[0007] Furthermore, to prevent the cutting disc of the handheld cutter from contacting the ground and causing damage during temporary idle periods, a buffer lifting mechanism is installed in the middle of the base, which is located directly below the operating lever. In addition, to achieve accurate material positioning, a material clamping component and a material correction auxiliary component are also installed on the base, with the material clamping component located on the side of the buffer lifting mechanism.

[0008] Furthermore, in order to achieve precise positioning of materials, the material correction auxiliary component includes a straightedge and an adjusting angle plate. The end face of the adjusting angle plate is parallel to the side of the straightedge. The straightedge is made of square tubing and is fixed horizontally on the base. The position of the straightedge on the base provides a reference for the placement of materials, so that the placement angle of the materials on the base is perpendicular to the edge of the base, which is convenient for subsequent cutting. The design of the adjusting angle plate is to position the width of the materials to facilitate subsequent batch processing.

[0009] Furthermore, in order to facilitate the adjustment of the distance between the adjusting angle plate and the straightedge and to adapt to the positioning of materials of different widths, a slot is provided in the base at the position of the adjusting angle plate. The adjusting angle plate is detachably installed on the base by bolts and with the help of the slot. The slot is designed as a long strip along the length of the base.

[0010] Furthermore, in order to achieve a buffering effect on the operating lever, the buffering and lifting mechanism includes a column vertically mounted on the base, an end cap fixed at the top of the column, a support plate slidably fitted on the outside of the column, and a spring fitted on the outside of the column at the bottom of the support plate. In order to ensure that the angle of the support plate always corresponds to the operating lever, the support plate and the column are connected by a key for circumferential positioning, so that the support plate can only slide up and down on the column, but cannot rotate in the circumferential direction.

[0011] Furthermore, to achieve material clamping and positioning, the material clamping assembly mainly consists of two parts: a locking mechanism and a clamping mechanism. The locking mechanism includes an adjusting seat mounted on a base, with a strip-shaped cross-shaped mounting groove. A flat-pull quick clamp is mounted on the top of the adjusting seat via a bolt assembly that engages with the cross-shaped mounting groove. The bolt assembly consists of mating hexagonal bolts and nuts, with the nuts positioned within the transverse slot of the cross-shaped mounting groove. The clamping mechanism includes a slide rail fixed to the base, with a clamping block slidably mounted on the slide rail. A hook is mounted on the side of the clamping block to engage with the pull ring of the flat-pull quick clamp. The clamping block has a long strip design, and the sliding direction of the slider is designed to be perpendicular to the guide rail.

[0012] Furthermore, to ensure the stability of the handheld electric cutter after it is fixed, there are two sets of quick-release clamp devices, and the two sets of quick-release clamp devices are set on the same side of the operating lever.

[0013] Furthermore, in order to enable quick assembly and disassembly of the handheld electric cutting machine, the quick-release clamping device includes a fixed clamping ring and a movable clamping ring; the fixed clamping ring is slidably fitted on the outside of the operating rod, and the fixed clamping ring is also provided with a quick-release bolt for positioning the fixed clamping ring; one end of the movable clamping ring is hinged to one end of the fixed clamping ring, and the other end of the movable clamping ring and the fixed clamping ring are locked and fixed by a quick-locking buckle.

[0014] Furthermore, both the fixed hoop and the movable hoop are equipped with protective pads on their inner sides. On the one hand, this can prevent the quick-release clamping device from damaging the handheld electric cutter when it is clamped and fixed. On the other hand, it can increase the friction between the quick-release clamping device and the handheld electric cutter, thereby improving the stability of the handheld electric cutter after it is fixed.

[0015] Furthermore, to facilitate carrying the operating frame, a handle is also installed at the end of the base.

[0016] Beneficial effects:

[0017] This utility model has a compact and simple structure, making it convenient for maintenance personnel to carry to the maintenance site. The electric cutter is positioned using a frame, offering significantly greater stability than handheld cutters. Furthermore, the frame's mounting unit, straightedge, and adjusting plate assist operators in correcting the angles of the raw materials and securing them to prevent displacement during cutting. This results in a smoother, higher-quality cut, facilitating on-site maintenance and reducing maintenance time. Moreover, the fixed position of the electric cutter on the frame throughout the operation facilitates batch cutting and requires less operator skill. Attached Figure Description

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. 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.

[0026] Example:

[0027] In response to the current problems encountered during the maintenance of factory equipment, when using a cutting machine for material cutting, stability relies entirely on the operator's handheld operation, which requires a high level of experience and makes it difficult to control precision. Dimensional errors are also prone to occur, causing difficulties for on-site welding repairs and maintenance. To address these issues, we propose a portable handheld cutting machine auxiliary operating frame.

[0028] like Figure 1-3 As shown, this embodiment provides a handheld cutting machine operating frame, including a base 1; an operating lever 8 is rotatably mounted on one end of the top of the base 1 via a hinge seat 7, and a quick-release clamp device 9 is installed on the operating lever 8 to fix the handheld electric cutting machine 10. The handheld electric cutting machine 10 is detachably mounted on one side of the operating lever 8 using the quick-release clamp device 9, and the whole operation process is quick and convenient.

[0029] To prevent the cutting disc of the handheld cutter from coming into contact with the ground and being damaged during temporary downtime, a buffer lifting mechanism is installed in the middle of the base 1. The buffer lifting mechanism is located directly below the operating lever 8. In addition, to achieve accurate material positioning, a material clamping component and a material correction auxiliary component are installed on the base 1, and the material clamping component is located on the side of the buffer lifting mechanism.

[0030] To achieve precise material positioning, the material correction auxiliary components include a straightedge 2 and an adjusting angle plate 4. The end face of the adjusting angle plate 4 is parallel to the side of the straightedge 2. The straightedge 2 is made of square tubing and is horizontally fixed on the base 1. The position of the straightedge 2 on the base 1 provides a reference for the placement of the material, so that the placement angle of the material on the base 1 is perpendicular to the edge of the base 1, which is convenient for subsequent cutting. The design of the adjusting angle plate 4 is to position the width of the material to facilitate subsequent batch processing.

[0031] To facilitate the adjustment of the distance between the adjusting angle plate 4 and the straightedge 2 and to accommodate the positioning of materials of different widths, a slot 3 is provided on the base 1 at the position of the adjusting angle plate 4. The adjusting angle plate 4 is detachably installed on the base 1 by bolts and with the help of the slot 3. The slot 3 is designed as a long strip along the length of the base 1.

[0032] like Figure 4 As shown, in order to achieve a buffering effect on the operating lever 8, its buffering and lifting mechanism includes a column 15 vertically mounted on the base 1, an end cap fixed at the top of the column 15, a support plate 17 slidably mounted on the outside of the column 15, and a spring 16 mounted on the outside of the column 15 at the bottom of the support plate 17. In order to ensure that the angle of the support plate 17 always corresponds to the operating lever 8, the support plate 17 and the column 15 are connected by a key for circumferential positioning, so that the support plate 17 can only slide up and down on the column 15, but cannot rotate in the circumferential direction.

[0033] To achieve material clamping and positioning, the material clamping assembly mainly consists of two parts: a locking mechanism and a clamping mechanism; such as Figure 4 As shown, the locking mechanism includes an adjusting seat 12 mounted on the base 1. The adjusting seat 12 has a strip-shaped cross-shaped mounting groove 121. A flat-pull quick clamp 13 is mounted on the top of the adjusting seat 12 through a bolt assembly that engages with the cross-shaped mounting groove 121. The bolt assembly consists of a hexagonal socket head cap screw and a nut that engage with each other. The nut is located in the transverse slot 3 of the cross-shaped mounting groove 121. The clamping mechanism includes a slide rail 5 fixed on the base 1. A clamping block 6 is slidably mounted on the slide rail 5. A hook 14 is mounted on the side of the clamping block 6 to engage with the pull ring of the flat-pull quick clamp 13. The clamping block 6 has a long strip design, and the sliding direction of the slider is designed to be perpendicular to the ruler 2.

[0034] To ensure the stability of the handheld electric cutter 10 after it is fixed, it has two sets of quick-release clamp devices 9, and the two sets of quick-release clamp devices 9 are set on the same side of the operating lever 8.

[0035] To enable quick assembly and disassembly of the handheld electric cutter 10, such as Figure 5-6As shown, its quick-release clamping device 9 includes a fixed clamping ring 901 and a movable clamping ring 902; the fixed clamping ring 901 is slidably fitted on the outside of the operating rod 8, and the fixed clamping ring 901 is also provided with a quick-release bolt 903 for positioning the fixed clamping ring 901; one end of the movable clamping ring 902 is hinged to one end of the fixed clamping ring 901, and the other end of the movable clamping ring 902 and the fixed clamping ring 901 are locked and fixed by a quick-locking buckle 904.

[0036] Both the fixed clamping ring 901 and the movable clamping ring 902 are equipped with protective pads on their inner sides. On the one hand, this can prevent the quick-release clamping device 9 from damaging the handheld electric cutting machine 10 when it is clamped and fixed. On the other hand, it can increase the friction between the quick-release clamping device 9 and the handheld electric cutting machine 10, thereby improving the stability of the handheld electric cutting machine 10 after it is fixed.

[0037] To facilitate carrying the operating frame, a handle 11 is also installed at the end of the base 1.

[0038] 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.
