This application relates to the field of computer flat knitting machine base processing technology and provides a grinding device. In use, the grinding device in this application inverts the base top and bottom onto a worktable, clamps and positions the base using a fixture. After the base is positioned and fixed, a first linear drive device moves the sliding sleeve to a predetermined position along the height direction of the base, so that the grinding head of the first grinding die is on the same horizontal plane as the surface to be ground on the base. A second linear drive device aligns the two C-shaped grinding heads of the second mold with the horizontal positions of the ends on both sides of the base. By driving the worktable to reciprocate along the length direction of the base, the base is driven to reciprocate along the length direction of the base, thereby simultaneously grinding the bottom surface and ends of the base, resulting in high production efficiency.

Description

[0001] This application belongs to the field of computer flat knitting machine base processing technology, and particularly relates to a grinding device. Background Technology

[0002] During the operation of a computerized flat knitting machine, the head bearing will reciprocate at the end of the machine base. In order to ensure that the head bearing moves with low noise when it moves at the end of the machine base, and to ensure the flatness and installation accuracy of the machine base during installation, the bottom surface and the end surface of the machine base often need to be polished after the machine base is rough machined.

[0003] The existing computerized flat knitting machine base grinding device can only grind the end of the base. Before or after grinding the end of the base, the flatness of the bottom surface of the base also needs to be ground, which leads to complicated production process and steps and low production efficiency.

[0059] Currently, existing computerized flat knitting machine base grinding devices can only grind the ends of the base, resulting in low production efficiency.

[0060] To address the aforementioned problems, one embodiment of this application provides a polishing apparatus, such as... Figures 1 to 4As shown, the grinding device includes a base 1, a fixture 2, and a grinding tool 3. A worktable 11 is mounted on the base 1 and can slide along the length of the base 1. The length of the worktable 11 is aligned with the length of the base 1, and the worktable 11 has a working surface 111. The fixture 2 is mounted on the working surface 111 and is used to position and clamp the machine base 100. The machine base 100 can be fixed to the fixture 2 with its top and bottom inverted positions, and the length of the machine base 100 is aligned with the length of the worktable 11. The grinding tool 3 includes a gantry 31, a sliding sleeve 32, a first linear drive device 33, a first grinding tool 34, and a second grinding tool 35. The gantry 31 includes columns 311 respectively mounted on both sides of the base 1 and a crossbeam 312 spanned between the two columns 311. The length of the columns 311 is aligned with the height of the base 1. The sliding sleeve... The two ends of the slide sleeve 32 are respectively fitted onto the two columns 311 and can slide along the length direction of the columns 311; the first linear drive device 33 is set on the gantry 31, and the output end of the first linear drive device 33 is connected to the slide sleeve 32. The first linear drive device 33 is used to drive the slide sleeve 32 to perform reciprocating linear motion in the length direction of the columns 311; the first grinding tool 34 and the second grinding tool 35 are both set on the slide sleeve 32. The grinding head 341 of the first grinding tool 34 faces the working surface 111 of the base 100. The second grinding tool 35 includes two C-shaped grinding heads 351. Each C-shaped grinding head 351 is connected to the slide sleeve 32 through a second linear drive device 37. The second linear drive device 37 can drive the C-shaped grinding head 351 to perform reciprocating linear motion in the height direction perpendicular to the base 1. The two C-shaped grinding heads 351 can be respectively locked onto the ends 103 on both sides of the base 100.

[0061] In some embodiments of this application, such as Figures 1 to 3 As shown, the grinding device includes two fixtures 2, each of which is fixed to a machine base 100.

[0062] The grinding device includes two fixtures 2, both of which are mounted on the sliding sleeve 32, so as to process the two machine bases 100 at the same time, further improving production efficiency.

[0063] In some embodiments of this application, such as Figure 1 As shown, the fixture 2 includes a positioning mechanism 21 and a clamping mechanism 22. The positioning mechanism 21 is used to position the machine base 100, and the clamping mechanism 22 is used to fix the machine base 100.

[0064] When placing the machine base 100, the positioning mechanism 21 can quickly position the machine base 100. After the machine base 100 is positioned, the clamping mechanism 22 can fix the machine base 100 on the worktable 11 for convenient subsequent processing.

[0065] In some embodiments of this application, such as Figures 1 to 3 As shown, the positioning mechanism 21 includes two support frames 211, which are spaced apart on the working surface 111 along the length of the worktable 11. The end of the support frame 211 away from the working surface 111 is the support end 2111. The outer surface of the support end 2111 is adapted to the shape of the top surface 101 of the machine base 100. The support frame 211 is used to support the machine base 100, and the support end 2111 is used to position the top surface 101 of the machine base 100.

[0066] Two support frames 211 are provided to stably support the machine base 100. The end of the support frame 211 away from the working surface 111 serves as the support end 2111, and the outer surface of the support end 2111 is adapted to the shape of the top surface 101 of the machine base 100. When placing the machine base 100, the top and bottom of the machine base 100 are inverted, and the top surface 101 of the machine base 100 is positioned by the support end 2111. Because the outer surface of the support end 2111 is adapted to the shape of the top surface 101 of the machine base 100, rapid positioning can be achieved.

[0067] In some embodiments of this application, such as Figures 1 to 3 As shown, the clamping mechanism 22 includes two clamping tables 221, which are spaced apart along the length of the worktable 11. The machine base 100 is located between the two clamping tables 221. Each clamping table 221 is screwed with a clamping rod 222. The screwing direction of the clamping rod 222 is consistent with the length direction of the worktable 11. The clamping rod 222 can abut against / release the machine base 100 by tightening / loosening.

[0068] After the machine base 100 is positioned by the positioning mechanism 21, it is located between two fixture tables 221. By adjusting the clamping rods 222 on the fixture tables 221, the machine base 100 is clamped and fixed to facilitate subsequent processing.

[0069] In some embodiments of this application, as shown in the figure, a clamping piece 2221 is provided at one end of the clamping rod 222 near the base 100.

[0070] The aforementioned clamping piece 2221 is used to increase the contact area between the clamping rod 222 and the end face of the machine base 100, so that it can be more stable during clamping.

[0071] In some embodiments of this application, such as Figures 1 to 3 As shown, the grinding tool 3 also includes a rotary drive device 36, which is mounted on the sliding sleeve 32. The output shaft of the rotary drive device 36 is connected to the grinding head 341 of the first grinding tool 34. The rotary drive device 36 is used to drive the grinding head 341 of the first grinding tool 34 to rotate.

[0072] The aforementioned rotary drive device 36 is used to drive the head of the first grinding tool 34 to rotate. Since the previous processing steps of the bottom surface 102 of the machine base 100 are rougher than those of the end 103, it takes longer to grind the bottom surface 102 of the machine base 100. Therefore, the rotary drive device 36 is set so that the grinding head 341 of the first grinding tool 34 rotates and grinds while the machine base 100 reciprocates, so as to achieve a better and faster effect when grinding the bottom surface 102 of the machine base 100.

[0073] It is understood that the aforementioned rotary drive device 36 can be a motor, with the fixed end of the motor connected to the sliding sleeve 32, and the output shaft of the motor connected to the transmission connection or directly connected to the grinding head 341 of the first grinding tool 34, so as to drive the grinding head 341 of the first grinding tool 34 to rotate around its axis.

[0074] In some embodiments of this application, such as Figures 1 to 3 As shown, the column 311 has a groove 3111 along its length, and the sliding sleeve 32 has a protrusion 321 corresponding to the groove 3111. The protrusion 321 can slide in the groove 3111 to guide the sliding sleeve 32 to slide in the length direction of the column 311.

[0075] The aforementioned groove 3111 and protrusion 321 can cooperate with each other. The protrusion 321 slides in the groove 3111 to play a guiding role, so that the sleeve 32 can slide along the length direction of the column 311.

[0076] In some embodiments of this application, such as Figures 1 to 3 As shown, the grinding device also includes a third linear drive device 38. The output end of the third linear drive device 38 is connected to one end of the worktable 11 along the length direction. The third linear drive device 38 enables the worktable 11 to move linearly along the length direction of the base 1.

[0077] The third linear drive device 38 is used to drive the worktable 11 to reciprocate along the length of the base 1, so as to drive the base 100 on the worktable 11 to reciprocate and perform grinding.

[0078] In some embodiments of this application, the first linear drive device, the second linear drive device, and the third linear drive device can all be either a pneumatic cylinder or a hydraulic cylinder.

[0079] It should be noted that the cylinder or hydraulic cylinder are only two specific devices in the specific implementation of the first linear drive device, the second linear drive device and the third linear drive device. Other devices that can drive the corresponding components to perform reciprocating linear motion should also be within the scope of protection of this application. For example, the first linear drive device can also be a wire rope assembly, the second linear drive device can also be an electric push rod, and the third linear drive device can also be a lead screw and nut assembly.

[0080] In some embodiments of this application, such as Figures 1 to 3 As shown, the gantry 31 also includes a crossbeam 312, the two ends of which are connected to the tops of two columns 311 respectively.

[0081] The aforementioned gantry 31 also includes a crossbeam 312, with both ends of the beam connected to the tops of two columns 311 respectively, which can improve the stability of the gantry 31, and the sliding sleeve 32 can be limited by the crossbeam 312 when it moves in a straight line along the columns 311 of the gantry 31.

[0082] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
