Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinding production, in particular to a centerless grinding material pressing device. Background Art

[0002] Centerless grinding, also known as centerless grinding, is a type of grinding process. It has two grinding wheels, a guide wheel and a grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the pad, and the grinding wheel grinds the workpiece. Centerless grinding belongs to the peripheral grinding method.

[0003] According to the search, Chinese patent literature, announcement number: CN208961640U, discloses a centerless grinding press device, which sets a press plate above the gap between the grinding wheel and the workbench. When the tubular material bounces up and collides with the press plate above, it returns to the workbench. In order to prevent the press plate from generating large stress when colliding with the tubular material, thereby causing the tubular material to deform, the elastic telescopic rod can buffer this stress, and can effectively prevent the uneven grinding caused by the excessive vibration of the tubular material when the centerless grinding is used. However, when processing tubular materials of different specifications during use, it is impossible to uniformly press the materials, which leads to more limited use. In addition, when the press plate is used, it is easy to cause large stress to be generated during collision, causing the tubular material to pop out. The press stability is poor, which easily leads to material deviation. Utility Model Content

[0032] Specifically, a first chute 301 is provided on each of the left and right sides of the inner side of the buffer seat 3. A first slider 302 is provided inside the first chute 301. Several groups of buffer springs are fixedly installed between the buffer seat 3 and the support frame 4. Advantageously, the support frame 4 slides inside the buffer seat 3, thereby providing buffering through the groups of buffer springs. This helps prevent excessive force from causing material deviation and affecting processing accuracy and stability.

[0033] Specifically, the support frame 4 has a T-shaped structure, with a second chute 401 defined on the top side of the support frame 4. A second slider is disposed within the second chute 401. The second chute 401 and the second slider form a set, with two sets provided in total. The second slider is fixedly mounted on the bottom side of the second workbench 7.

[0036] Example 2:

[0037] like Figure 1-5 As shown, as an improvement to the previous embodiment. Specifically, a No. 3 chute 1001 is provided on the bottom side of the base 10, a No. 3 slider is provided inside the No. 3 chute 1001, and a fastening spring 1002 is fixedly installed between the No. 3 chute 1001 and the No. 3 slider.

[0038] Specifically, two sets of press frames 11 are provided, and a second arc-shaped groove 1101 is formed on the bottom side of the press frame 11. The press frame 11 is fixedly mounted on the bottom side of the third slider, and the dry group of balls 12 is movably mounted on the inner side of the second arc-shaped groove 1101. The advantage is that by activating the cylinder 9 to drive the base 10 and the press frame 11 downward, the second arc-shaped groove 1101 is used to limit the upper end of the outer side of the material and press the material, thereby preventing the material from being ejected or deflected due to a large force, and improving the grinding stability.

[0039] When in use, the material is placed inside the No. 1 arc groove 501 on the top side of the No. 1 workbench 5 and the No. 2 workbench 7, which is convenient for loading and at the same time limits the bottom end of the material. Under the action of the ball 12, it is convenient for the material to rotate during grinding, thereby improving the grinding effect. Subsequently, the base 10 and the pressing frame 11 are driven downward by starting the cylinder 9, so that the upper end of the outer side of the material is limited and pressed through the No. 2 arc groove 1101, thereby avoiding the phenomenon of the material being ejected and offset due to a large force, thereby improving the grinding stability. In the process of extrusion, the pressing frame 11 moves under the action of the No. 3 slider, and then tightens the spring 1 Under the action of 002, the No. 3 slider is driven to move and reset on the inner side of the No. 3 slide 1001, so as to facilitate automatic adjustment according to the material specifications. When it is necessary to grind materials of other specifications, the threaded rod 6 is rotated at this time, and then the No. 2 workbench 7 is moved on the top side of the support frame 4 under the action of the thread, so as to facilitate the adjustment of the distance between the No. 1 workbench 5 and the No. 2 workbench 7 according to the needs. At the same time, during the grinding process, when the force generated by the grinding material is large, the support frame 4 slides on the inner side of the buffer seat 3, so as to be buffered by several groups of buffer springs, which is conducive to avoiding excessive force and causing material deviation, affecting processing accuracy and stability.
