Description

Technical Field

[0001] The invention relates to the technical field of cylinder clamps, in particular to a cylinder clamp with elastic positioning for a grinding machine. Background Art

[0002] The clamping is achieved by using an up and down moving oil cylinder on the equipment to press the cylinder body, completing the positioning and clamping functions of the cylinder body in the grinder. Because the cylinder body before grinding is a blank, the blank size varies greatly, generally fluctuating around 2 mm, so the surface or center line position used as the positioning reference fluctuates greatly. The positioning elements of the fixture are fixed in size, and the positioning error is large, resulting in the flash and runner remnants on the blank after grinding being around 2-3 mm, while the customer requires no more than 1 mm. In this way, manual grinding is required after grinding. If the grinding machine distance is adjusted to reduce the grinding residue, the positioning error is large due to the large change in the cylinder body's external size, and the cylinder body is easily over-grinded, resulting in scrap.

[0003] The traditional processing method requires the modification of the fixture to achieve precise positioning of the fixture positioning mechanism through pneumatic or hydraulic structure, which is too costly to implement. Because the grinder is an exchange workbench, two fixtures are installed on one grinder, which makes clamping and positioning inconvenient and cannot meet the clamping requirements of cylinders with different depths and diameters. Summary of the invention

[0004] The object of the present invention is to provide a cylinder clamp with elastic positioning for a grinding machine to solve the related problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a cylinder clamp with elastic positioning for a grinding machine, comprising a third support, a fourth support and a bottom plate, the fourth support being installed at the top end of the bottom plate, and the third support being installed at the top end of the fourth support, the first support being installed at the top end of the bottom plate, the second support being installed at the side of the bottom plate away from the first support, a first column being arranged on the side of the top end of the bottom plate close to the second support, and a second elastic pin being sleeved on the outer wall of the first column, a second column being installed on the side of the bottom plate close to the first support, and a first elastic pin being sleeved on the outer wall of the second column, elastic support grooves being provided inside the first column and the second column, and a mold spring being provided on the inner wall of the elastic support groove, the top end of the mold spring being in contact with the bottom end of the second column, a support plate being installed at the bottom end of the bottom plate, and a movable frame being installed at the bottom end of the support plate, a mounting plate being arranged below the movable frame, and a mounting mechanism for fixing the position of the mounting plate being arranged inside the movable frame.

[0006] The technical solution provides a cylinder clamp with elastic positioning for a grinding machine, wherein the second column and the first column are both provided with positioning grooves adapted to the top of the bottom plate.

[0009] The technical solution provides a cylinder clamp with elastic positioning for a grinding machine, wherein a positioning sleeve is arranged below the mounting plate, and a mounting groove is provided inside the positioning sleeve.

[0010] The technical solution provides a cylinder clamp with elastic positioning for a grinding machine, wherein the mounting mechanism includes a movable groove and a guide rod, movable grooves are opened on both sides of the movable frame, and a push frame is installed inside the movable groove, which passes through the fixed groove and extends to the top of the movable groove, and an insert block adapted to the inner wall of the fixed groove is installed on the outer wall of the push frame, and a guide rod is installed longitudinally inside the movable groove.

[0011] The technical solution provides a cylinder clamp with elastic positioning for a grinding machine, wherein the outer wall of the guide rod is sleeved with a rigid spring, and the two sides of the rigid spring are respectively connected to the outer walls of the movable groove and the push frame.

[0012] Compared with the prior art, the present invention provides a cylinder clamp with elastic positioning for a grinding machine, which has the following beneficial effects: 1. The present invention solves the problem of the positioning element adapting to the change of the positioning opening through a tapered positioning design, ensures that the first elastic pin and the second elastic pin are always in contact with the center holes of different diameters on the positioning surface of the cylinder casting, and meets the support problem of different cylinder casting point diameter holes.

[0013] 2. The present invention pushes the push frame to the rear side and inserts it into the fixed groove, so that the push frame moves in the guide rod, and then the rigid spring is stretched. After the position of the movable frame is fitted with the top of the mounting plate, the push frame is released, and the elastic force of the rigid spring itself drives the insert block to be positioned with the groove in the fixed groove, thereby achieving the effect of rapid installation and positioning.
