Technical Field
[0001] This application relates to the field of angle grinder technology, and in particular to an auxiliary fixing platform for a handheld angle grinder. Background Technology
[0002] An angle grinder, also known as a grinding machine or disc grinder, is an abrasive tool used for cutting and polishing. Common benchtop cutting machines are too large to be easily moved, while smaller angle grinders are usually handheld for portability. However, handheld angle grinders have lower accuracy when cutting, thus requiring further improvement. Utility Model Content
[0003] To improve the cutting accuracy of handheld angle grinders, this application provides an auxiliary fixing table for handheld angle grinders.
[0004] The auxiliary mounting platform for a handheld angle grinder provided in this application adopts the following technical solution:
[0005] A handheld angle grinder auxiliary fixing platform includes a chassis, a mounting arm hinged to the chassis, a handheld angle grinder body for cutting workpieces being detachably connected to the free end of the mounting arm, a clamping mechanism for clamping and fixing workpieces on the chassis, and an elastic element on the chassis that normally forces the free end of the mounting arm to swing away from the chassis.
[0006] By adopting the above technical solution, the handheld angle grinder body is mounted on the free end of the mounting arm and clamped to the workpiece to be cut by the clamping mechanism. A force is applied to the handheld angle grinder body, causing the free end of the mounting arm to swing around the hinge point towards the chassis. At this time, the elastic element undergoes elastic deformation and has elastic potential energy, thereby causing the handheld angle grinder to move towards the workpiece. This allows the cutting wheel of the handheld angle grinder body to cut the workpiece. After cutting, the handheld angle grinder body is released, and the elastic element forces the mounting arm to return to its original position, causing the cutting wheel of the handheld angle grinder body to detach from the workpiece. This prevents cutting deviations caused by hand tremors and significantly improves cutting accuracy and safety.
[0007] Preferably, the chassis is fixedly connected to a pair of spaced-apart hinge plates, and a hinge shaft is rotatably connected between the two hinge plates. The end of the mounting arm is fixedly connected to the outer wall of the hinge shaft.
[0008] By adopting the above technical solution, the mounting arm can rotate smoothly around the hinge axis, improving the stability and accuracy of the handheld angle grinder during the cutting process. At the same time, the hinge axis design makes the movement of the mounting arm smoother, reducing mechanical wear and extending the service life of the equipment.
[0009] Preferably, the free end of the mounting arm is fixedly connected to a mounting base, the mounting base has a mounting groove for the head of the handheld angle grinder body to slide and insert, and the mounting base is provided with a fixing member for fixing the handheld angle grinder body.
[0010] By adopting the above technical solution, the design of the mounting slot allows the head of the handheld angle grinder to slide and be inserted, facilitating quick installation and removal of the handheld angle grinder and improving operational convenience and work efficiency. The inclusion of a fixing component further ensures the stability of the handheld angle grinder during operation, preventing it from falling off due to vibration and enhancing safety.
[0011] Preferably, the outer wall of the head of the handheld angle grinder body is provided with a threaded hole, and the fixing member is a fixing bolt, which is threaded through the mounting base and threadedly connected to the threaded hole.
[0012] By adopting the above technical solution, the handheld angle grinder body and the mounting base are quickly and reliably fixed by fixing bolts, ensuring that the handheld angle grinder body will not loosen during the cutting process, thus improving the stability and safety of the cutting operation.
[0013] Preferably, the side wall of the mounting base is provided with a sliding groove that communicates with the mounting groove for the fixing bolt to slide through. The length direction of the sliding groove is parallel to the length direction of the mounting groove. The mounting base is provided with a threaded sleeve that slides through the sliding groove. The fixing bolt is threaded through the threaded sleeve. The mounting base is provided with a first adjustment component that adjusts the sliding position of the threaded sleeve.
[0014] By adopting the above technical solution, the sliding groove allows the fixing bolt to slide along its length within the mounting groove, facilitating adjustment of the handheld angle grinder body's position and improving installation flexibility. The sliding connection between the threaded sleeve and the sliding groove ensures that the fixing bolt can stably secure the handheld angle grinder body in different positions, enhancing fixing reliability. The first adjustment component allows the operator to easily adjust the position of the threaded sleeve, thereby adjusting the position of the cutting wheel on the handheld angle grinder body.
[0015] Preferably, the outer wall of the screw sleeve is fixedly connected to a connecting block exposed to the mounting base, and the first adjusting component includes a first adjusting screw rotatably connected to the mounting base, the first adjusting screw being threaded through the connecting block.
[0016] By adopting the above technical solution, the connection block enables the first adjusting screw to form an effective mechanical connection with the screw sleeve. By rotating the first adjusting screw, the sliding position of the screw sleeve in the groove can be adjusted, thereby adjusting the position of the fixing bolt, and then adjusting the position of the cutting wheel of the handheld angle grinder body.
[0017] Preferably, the clamping mechanism includes a fixed angle iron fixedly connected to the chassis and a movable angle iron slidably connected to the chassis in a direction toward or away from the fixed angle iron, and the chassis is provided with a second adjustment component for adjusting the sliding position of the movable angle iron.
[0018] By adopting the above technical solution, the position of the movable angle iron is adjusted by the second adjusting component, allowing the movable angle iron to move closer to or further away from the fixed angle iron, thereby achieving stable clamping of workpieces of different sizes. This design not only improves the clamping stability of the workpiece but also enhances the applicability of the device, enabling it to adapt to workpieces of various sizes and improving cutting accuracy and safety.
[0019] Preferably, the chassis is fixedly connected to a nut, and the second adjusting component includes a second adjusting screw threaded through the nut, the second adjusting screw being rotatably connected to a movable angle iron.
[0020] By adopting the above technical solution, the second adjustment component is rotatably connected to the movable angle iron through the second adjustment screw threaded through the nut, realizing precise adjustment of the sliding position of the movable angle iron. This allows for more flexible adjustment of the workpiece clamping position, ensuring stable workpiece clamping and improving cutting accuracy and safety.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. The handheld angle grinder body is mounted on the free end of the mounting arm and clamped to the workpiece to be cut by the clamping mechanism. Applying force to the handheld angle grinder body causes the free end of the mounting arm to swing around the hinge point toward the chassis. At this time, the elastic element undergoes elastic deformation and has elastic potential energy, thereby causing the handheld angle grinder to move toward the workpiece. This allows the cutting wheel of the handheld angle grinder body to cut the workpiece. After cutting, the handheld angle grinder body is released, and the elastic element forces the mounting arm to return to its original position, causing the cutting wheel of the handheld angle grinder body to detach from the workpiece. This prevents cutting deviations caused by hand shaking and significantly improves cutting accuracy and safety.
[0023] 2. The sliding groove allows the fixing bolt to slide along its length within the mounting groove, facilitating adjustment of the handheld angle grinder body's position and improving installation flexibility. The sliding connection between the threaded sleeve and the sliding groove ensures that the fixing bolt can stably secure the handheld angle grinder body in different positions, enhancing fixing reliability. The first adjustment component allows the operator to easily adjust the position of the threaded sleeve, thereby adjusting the position of the cutting wheel on the handheld angle grinder body.
