AI Technical Summary
The existing file machine is prone to radial swing during the reciprocating motion of the file, resulting in problems such as unevenness and over-grinding on the polished surface, affecting the processing quality of the product.
A limited file machine was designed. A guide rod movably connected to the chuck was set on the support, so that the chuck could only move along the axial direction of the guide rod to prevent the file from swinging radially. A T-shaped structure with an integral fixed clamp arm and a guide arm and a guide hole was adopted to reduce friction and improve guiding accuracy.
It effectively avoids the radial swing of the file, improves the flatness and smoothness of the polished surface, and improves the processing quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding and polishing, in particular to a position-limiting file machine. Background Art
[0002] File machines are often used in deburring equipment. File machines process workpieces through the reciprocating motion of files. Electric file machines use electricity to achieve high-speed reciprocating motion of files. They are suitable for metal grinding, trimming, deburring and other purposes. Pneumatic file machines use compressed air as a power source. They are small in size, light in weight, easy to carry and use, and are suitable for the processing of hardware, plastics and other products.
[0003] Existing file machines may produce a certain amount of radial swing during the reciprocating motion of the file. Such radial swing may cause the polished surface to become uneven or over-polished, making it impossible to ensure the flatness and smoothness of the polished surface, thereby affecting the processing quality of the product.

[0019] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0020] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0021] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0022] See Figures 1 to 3 As shown, the structure of the utility model is: a position-limiting file machine, comprising a fixed seat 1, a support 4 arranged at one end of the fixed seat 1, a file machine body 2 is provided on the fixed seat 1, the output end of the file machine body 2 passes through the support 4 and is connected with a chuck 3 for clamping a file 6, the file machine body 2 is used to drive the chuck 3 to reciprocate, and guide rods 5 movably connected to the chuck 3 are provided on both sides of the output end of the file machine body 2 on the support 4. Under the action of the guide rod 5, the chuck 3 can only move axially along the guide rod 5, thereby avoiding the radial swing of the file 6 during grinding, which can effectively improve the quality of grinding.
[0023] Furthermore, the chuck 3 includes a mounting portion for clamping the file 6 and a guide portion cooperating with the guide rod 5. Specifically, the file is connected to the output end of the file machine body 2 through the mounting portion. With the cooperation of the guide portion and the guide rod 5, the file 6 is prevented from generating radial swing during processing.
[0024] like Figure 2 As shown, the mounting portion includes a fixed clamping arm 301 connected to the output end of the file machine body 2, and a mounting groove 302 for accommodating the file 6 is provided on the fixed clamping arm 301. The mounting groove 302 is provided with a movable clamping arm 303, and the movable clamping arm 303 is provided with a bolt 304. The bolt 304 is threadedly connected to the fixed clamping arm 301. Specifically, the fixed clamping arm 301 is installed to the output end of the file machine body 2, and then the handle of the file 6 is inserted into the mounting groove 302, and then the bolt 304 is tightened so that the movable clamping arm 303 firmly clamps the file 6.
[0025] like Figure 2 As shown, the guide portion includes a guide arm 307 arranged on the fixed clamp arm 301. The fixed clamp arm 301 and the guide arm 307 are integrally formed and have a "T"-shaped structure. A guide hole is provided on the guide arm 307 to cooperate with the guide rod 5. Specifically, when the file 6 is grinding, the fixed clamp arm 301 can only move axially under the action of the guide hole on the guide arm 307 and the guide rod 5, thereby preventing the file 6 from generating radial swing that affects the quality of grinding.
[0026] like Figure 2 As shown, a weight-reducing hole 305 is provided on the guide arm 307 . Specifically, the weight-reducing hole 305 is used to reduce the weight of the guide arm 307 and reduce the load on the output end of the file machine body 2 .
[0027] like Figure 2 As shown, a sliding sleeve 306 is provided in the guide hole. Specifically, the sliding sleeve 306 is used to reduce the friction between the guide hole and the guide rod 5, while making the guide hole and the guide rod 5 fit more tightly, further reducing the swing and deviation of the fixed clamp arm 301 during reciprocating motion.
[0028] like Figure 3 As shown, the fixing base 1 is provided with a receiving groove 101 for accommodating the file machine body 2, and the receiving groove 101 is provided with a fixing block 102 for fixing the file machine body 2. Specifically, the file machine body 2 is installed on the fixing base 1 through the receiving groove 101, and the file machine body 2 is firmly clamped in the receiving groove 101 by the fixing block 102. This can effectively reduce the vibration of the file machine body 2 during operation and prevent the file 6 from generating vibration marks on the workpiece surface when grinding, which affects the surface quality.
[0029] During specific use, during processing, the file machine body 2 is installed on the deburring machine through the fixed seat 1, and then the file 6 for grinding is clamped on the chuck 3. The file machine body 2 drives the chuck 3 to reciprocate, driving the file 6 to grind the workpiece. With the cooperation of the guide rod 5 and the chuck 3, the chuck 3 can only move axially along the guide rod 5, thereby avoiding radial swing of the file 6 during the reciprocating motion, which can effectively improve the quality of grinding.
[0030] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
