Description

Technical Field

[0001] The utility model relates to the technical field of cam processing, in particular to a lathe supporting frame for cam processing. Background Art

[0002] At present, the turning of various engine cams is generally carried out on special machine tools. During the turning process of the camshaft, the camshaft usually has a long length and a complex shape, which makes the camshaft easy to deform during the processing. In order to improve the rigidity of the workpiece and reduce the bending deformation and vibration of the workpiece caused by cutting force and gravity, a cam support frame is used for support. The existing support frames are often matched with the camshaft and fixed at a supporting point for support. They cannot adapt to camshafts of different lengths and sizes. Therefore, a lathe support frame for cam processing is needed. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4A cam processing lathe support frame is slidably connected to a slide plate 4 of a mounting seat 1, and includes a main body 5. The main body 5 includes two connecting plates 51. A nut 52 is welded on one connecting plate 51, and a bolt 53 is rotated on the nut 52. The other connecting plate 51 is provided with a hole for the bolt 53 to pass through. A pushing frame 54 is respectively arranged on the side of the two connecting plates 51. The two pushing frames 54 and the two connecting plates 51 are in contact with the slide plate 4. When in use, the operator sleeves the body 5 on the slide plate 4, then screws the bolt 53 onto the nut 52, and then moves the pushing frame 54 to adjust the supporting position of the cam 3 supported by the bolt 53, and then adjusts the height of the bolt 53 by tightening or loosening the bolt 53, thereby ensuring that the bolt 53 can contact the cam 3 and support the cam 3, keeping the bolt 53 in a horizontal position, and preventing the cam 3 from being flawed or damaged due to unbalanced force during processing, resulting in damage to the quality of the cam 3 and affecting its use. The utility model can quickly adjust the supporting point position of the body 5 through the pushing frame 54 to improve the processing speed, and at the same time use the tightening or loosening of the bolt 53 to adjust the height of the bolt 53 to adapt to different sizes of the cam 3, ensure that the cam 3 and the processing point of the lathe 2 are at the same height, so that the force of the cam 3 is balanced, the processing quality of the cam 3 is ensured, and the operation is simple and convenient.

[0019] In some embodiments, the top of the bolt 53 is smooth. The smooth top of the bolt 53 can ensure that when the bolt 53 contacts the cam 3, the burrs or impurities on the top of the bolt 53 will not scratch the cam 3, causing damage to the cam 3 and affecting the use of the cam 3, thereby ensuring the quality of the cam 3.

[0020] In some embodiments, a rubber strip is provided on one side of the two push racks 54 close to the slide 4. When the operator places the body 5 on the slide 4, the rubber strip can not only increase the friction between the push rack 54 and the slide 4, thereby making the body 5 more stable when supporting the cam 3, but also protect the push rack 54 from being scratched by the slide 4, thereby increasing the service life of the body 5.

[0021] In some embodiments, the push frame 54 includes a first moving frame 541 and a second moving frame 542, and the second moving frame 542 is provided with a first spring rod 543, and the first spring rod 543 is connected to the first moving frame 541. When the slide plate 4 on the mounting seat 1 is of a high height (i.e., thick), the operator only needs to pull the first moving frame 541 and the second moving frame 542 apart, and then the first spring rod 543 in the second moving frame 542 moves in the first moving frame 541, thereby increasing the distance between the two connecting plates 51, and then is sleeved on the slide plate 4, and finally the first moving frame 541 and the second moving frame 542 are brought close to each other by the resetting of the first spring rod 543, and are clamped together on the slide plate 4 for fixing, and can be freely adjusted according to the thickness of the slide plate 4, and the operation is simple and convenient.

[0022] In some embodiments, the first moving frame 541 and the second moving frame 542 are both provided with a second spring rod 544, and each second spring rod 544 is respectively connected to a connecting plate 51. When the width of the slide plate 4 on the mounting seat 1 is relatively wide, the operator can pull the two push frames 54 to move in opposite directions, and then the second spring rods 544 on the first moving frame 541 and the second moving frame 542 of the two push frames 54 respectively move in the two connecting plates 51, so that the distance between the two push frames 54 and the two connecting plates 51 increases, and then they are sleeved on the slide plate 4, and finally the first moving frame 541 and the second moving frame 542 are moved closer to each other by resetting the second spring rod 544, and are clamped together on the slide plate 4 for fixing, which can be adjusted according to the width of the slide plate 4, is simple to operate and has wide applicability, and can move the body 5 on the slide plate 4 by pulling the two push frames 54 away from the slide plate 4, and quickly move to a suitable supporting point to support the cam 3, which is very convenient.

[0023] In some embodiments, grooves 545 are provided on both push racks 54. When the operator uses the lathe 2 to process the cam 3 and adjusts the body 5 to move to a suitable position to support the cam 3 according to the length of the cam 3, the operator only needs to place fingers in the grooves 545 on the upper and lower sides of the two push racks 54, and then move the push racks 54, so that the body 5 moves on the slide 4 until it moves to a suitable position. The grooves 545 can increase the contact area between the operator's fingers and the body 5, ensuring that the operator will not slip and cause hand injuries when moving the body 5, thereby improving the safety of the processing lathe 2.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
