Description

Technical Field

[0001] This utility model relates to the field of steel component processing, and in particular to a fixing device for grinding steel components. Background Technology

[0002] During the processing of steel components, surface defects such as oxide scale, burrs, and weld beads need to be removed by grinding to ensure the quality of subsequent painting and assembly processes. When grinding steel components, a fixing device is required to secure them to ensure the quality and stability of the grinding process.

[0003] A search of Chinese patents revealed publication number CN220094245U, which discloses a fixing device for parts grinding. This device relates to the field of parts grinding fixing technology and addresses the problem that most existing grinding machines use electromagnets for fixing, which can only hold iron-containing products and are difficult to fix non-iron products, resulting in poor applicability. The device comprises a lower base plate at the lower end of an upper cover plate, an electromagnet inside the lower base plate, a fixing seat on the upper surface of the upper cover plate, a fixing slot on the upper surface of the fixing seat, and the fixing slot and fixing seat being an integral structure. The fixing slot contains the product. The device also includes a movable groove disposed inside the fixing seat, and the movable groove and fixing seat being an integral structure; and a compression spring disposed inside the movable groove, one end of the compression spring having a pressing seat.

[0004] Existing fixing devices cannot be adjusted in size; generally, the size of fixing devices is fixed and can only fix steel components of a specific size. If it is necessary to fix steel components of different sizes, the fixing device needs to be replaced, which increases the cost of use, reduces practicality and applicability, and is inconvenient to use. In order to solve the above problems, we propose a fixing device for grinding steel components. Utility Model Content

[0005] The purpose of this invention is to provide a fixing device for grinding steel components, the advantage of which is that its size can be adjusted.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixing device for grinding steel components, including a base, a clamping mechanism provided on the top of the base, a support rod provided on the top of the clamping mechanism, a fixing rod bolted to the top of the support rod, a telescopic rod slidably sleeved on the inner wall of the fixing rod, a screw threadedly connected to the inner wall of the telescopic rod, and the screw rotatably sleeved with the inner wall of the fixing rod, a fixing mechanism provided at one end of the telescopic rod, a clamping head provided on the surface of the fixing mechanism, a fixing block rotatably sleeved on the surface of the screw, and the fixing block bolted to the surface of the fixing rod, a toothed plate slidably connected to the inner wall of the fixing block, a fixing bolt rotatably connected to the top of the toothed plate, and the fixing bolt rotatably sleeved with the inner wall of the fixing block, and a toothed ring embedded in the surface of the screw, and the toothed ring meshing with the toothed plate.

[0007] By adopting the above technical solution, the rotating head drives the screw to rotate, which in turn causes the telescopic rod to move the clamping head. This movement of the clamping head changes the distance between the clamping heads, thus achieving the purpose of size adjustment. This reduces usage costs, improves practicality and applicability, and facilitates use. After adjusting the size, rotating the fixing bolt engages the toothed plate with the toothed ring, thereby fixing the screw and preventing it from rotating. This prevents the clamping head from loosening, ensures the stability of the fixation, and improves practicality.

[0008] The present invention is further configured such that: the clamping mechanism includes a support plate, the bottom of the support plate is bolted to the top of the base, a motor is bolted to the bottom of the support plate, a gear is fixedly sleeved at the output end of the motor, two toothed rods mesh on the surface of the gear, and one end of the toothed rod is bolted to the bottom of the support rod.

[0009] By adopting the above technical solution, a clamping mechanism is set up. The motor drives the gear to rotate, the gear rotates and drives the rack to move, and the rack moves and drives the support rod to move the clamping head to clamp and fix the steel component. When disassembling, the motor reverses to release the clamping head, which facilitates assembly and disassembly.

[0010] The present invention is further configured such that: the fixing mechanism includes a fixing head, the fixing head is bolted to one end of the telescopic rod, and the fixing head is slidably sleeved with the clamping head; a fixing pin is provided through the inner wall of the fixing head and the clamping head, and a nut is threaded onto the surface of the fixing pin.

[0011] By adopting the above technical solution, a fixing mechanism is set up, the nut is loosened, the fixing pin is pulled out, the clamping head is removed, a new clamping head is installed into the fixing head, the fixing pin is inserted, and the nut is tightened, thus facilitating the replacement of the clamping head.

[0012] The present invention is further configured such that: a slider is bolted to the surface of the telescopic rod, and a groove is slidably connected to the surface of the slider, and the groove is formed on the inner wall of the fixed rod.

[0013] By adopting the above technical solution, and by setting up a sliding groove and a slider, the telescopic rod is prevented from shifting, thus improving stability.

[0014] The present invention is further configured such that a rotating head is bolted to one end of the screw.

[0015] By adopting the above technical solution, a rotating head is provided to facilitate the rotation of the screw.

[0016] The present invention is further configured such that the surface of the telescopic rod is printed with scale lines.

[0017] By adopting the above technical solution and setting scale lines, the size can be easily adjusted.

[0018] The present invention is further configured such that a rubber pad is adhered to the surface of the clamping head.

[0019] The above technical solution protects the steel components by installing rubber pads.

[0020] The present invention is further configured such that: a baffle is bolted to the surface of the support rod, and the baffle is slidably connected to the inner wall of the support plate.

[0021] By adopting the above technical solution, baffles are set to prevent debris and dust from entering the inner wall of the support plate during grinding, thus ensuring operational stability.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model achieves the purpose of size adjustment by rotating the rotating head, which drives the screw to rotate, and the screw to rotate the telescopic rod to move the clamping head. The movement of the clamping head changes the distance between the clamping heads, thereby reducing the cost of use, improving practicality and applicability, and making it convenient to use. 2. This utility model fixes the screw by rotating the fixing bolt after adjusting the size, causing the toothed plate to mesh with the toothed ring, thereby preventing the screw from rotating, preventing the clamping head from loosening, ensuring the stability of the fixation, and improving practicality.
