Abstract
Description
Technical Field
[0001] This utility model relates to the field of cylinder stop block processing technology, and in particular to a fixture for processing cylinder stop blocks. Background Technology
[0002] A cylinder is a cylindrical metal component that guides a piston to reciprocate linearly within the cylinder, and the stop block is an important part of it.
[0003] When machining cylinder blocks, they need to be clamped and restricted. Conventional fixtures usually clamp one cylinder block at a time, and the manual clamping and unclamping operations each time are cumbersome and affect the machining efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a fixture for machining cylinder stop blocks, thereby solving the problems mentioned in the background section.
[0005] A fixture for machining cylinder stop blocks includes a worktable, on which a limiting plate is movably adjustable and limited by bolts, and two clamping parts 1 movably adjustable and limited on the worktable by pins. Two limiting blocks are installed between the two clamping parts 1. A clamping part 2 is slidably disposed in the middle of the limiting blocks. A turntable rotating on the worktable is disposed between the two clamping parts 2. A support column 1 is eccentrically disposed on the upper surface of the turntable. An electric cylinder is rotatably supported on the worktable by the support column 2. The output end of the electric cylinder is rotatably connected to the support column 1 eccentrically fixed on the turntable.
[0006] By adopting the above technical solution, the device can place two blocks at the same time and clamp the blocks, saving time and operation steps for clamping the blocks.
[0007] The worktable has multiple threaded holes located below the limiting plate. The bolt can pass through the limiting plate and be threaded into one of the threaded holes to limit the limiting plate on the worktable. The worktable also has multiple slots located below the clamping part one. The pin can pass through the clamping part one and be inserted into the slots to restrict the movement of the clamping part one.
[0008] By adopting the above technical solution, the positions of clamping part one and limiting plate are adjusted according to the size of the stop block, so that the turntable can push clamping part two to clamp the stop block.
[0009] The turntable has an elliptical structure, with its central part rotatably mounted on the worktable via a rotating shaft.
[0010] By adopting the above technical solution, the clamping part two cooperates with the clamping part one to clamp the stop block.
[0011] The second clamping part is arranged in an "I" shape, and the side edge of the end of the second clamping part near the turntable is chamfered.
[0012] The stop block is clamped by adopting the above technical solution.
[0013] The middle part of the clamping part is recessed, and when the pin is inserted into the slot, its highest point is not higher than the top surface of the clamping part.
[0014] By adopting the above technical solution, it is convenient to remove the pin and adjust the position of the clamping part.
[0015] The beneficial effects of the fixture for machining cylinder stop blocks according to this utility model are:
[0016] The position of the limiting plate on the worktable can be adjusted according to the size of the stop block. The limiting plate is threaded through the threaded hole by bolts, and the position of clamping part one is adjusted. A pin is inserted into the slot through clamping part one to limit clamping part one to the worktable. The stop block is placed between clamping part one and clamping part two, with one side of the stop block in contact with clamping part one and the other side in contact with the limiting plate. The electric cylinder then drives the turntable to rotate, which in turn drives clamping part two to move. Clamping part two then applies pressure to the stop block, and the stop block is clamped by clamping part one and clamping part two. This device can place two stop blocks at the same time and clamp them, saving time and operation steps when clamping the stop blocks. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0020] Reference Figure 1A fixture for machining cylinder stop blocks includes a worktable 1, a limiting plate 4 that is movable and limited by bolts 5, and two clamping parts 1 2 that are movable and limited by pins 3 on the worktable 1. Two limiting blocks 6 are installed between the two clamping parts 1 2. A clamping part 2 7 is slidably arranged in the middle of the limiting block 6. A turntable 8 that rotates on the worktable 1 is provided between the two clamping parts 2 7. A support column 10 is eccentrically provided on the upper surface of the turntable 8. An electric cylinder 9 is rotatably supported on the worktable 1 by the support column 2 11. The output end of the electric cylinder 9 is rotatably connected to the support column 10 that is eccentrically fixed on the turntable 8.
[0021] The position of the limiting plate 4 on the worktable 1 can be adjusted according to the size of the stop block. The bolt 5 passes through the limiting plate 4 and is threadedly connected to the threaded hole 102. The position of the clamping part 1 2 can be adjusted. The pin 3 passes through the clamping part 1 2 and is inserted into the slot 101 to limit the clamping part 1 2 on the worktable 1. After the above operations are completed, the stop block can be placed between the clamping part 1 2 and the clamping part 2 7, with one side of the stop block in contact with the clamping part 1 2 and the other side in contact with the limiting plate 4. Then, the electric cylinder 9 can be driven to push the turntable 8 to rotate. The turntable 8 pushes the clamping part 2 7 to move, and the clamping part 2 7 applies pressure to the stop block. At this time, the stop block is clamped by the clamping part 1 2 and the clamping part 2 7.
[0022] The device can place two blocks at the same time and clamp them, saving time and operating steps in clamping the blocks.
[0023] Multiple threaded holes 102 are provided on the worktable 1 below the limiting plate 4. Bolts 5 can pass through the limiting plate 4 and be threaded into one of the threaded holes 102 to limit the limiting plate 4 on the worktable 1. Multiple slots 101 are also provided on the worktable 1 below the clamping part 2. Pins 3 can pass through the clamping part 2 and be inserted into the slots 101 to limit the movement of the clamping part 2. Since the processed blocks may have different sizes, in order to ensure that the drive turntable 8 can push the clamping part 2 7 to cooperate with the clamping part 2 to clamp the block, the position of the limiting plate 4 and the clamping part 2 can be adjusted to clamp the block between the clamping part 2 and the clamping part 2 7.
[0024] The turntable 8 has an elliptical structure, with its central part rotatably mounted on the worktable 1 via a rotating shaft. When the turntable 8 rotates, it can simultaneously push the two clamping parts 7 to move, and then the two clamping parts 7 respectively cooperate with the corresponding clamping parts 1 to clamp the stop block.
[0025] The clamping part 2 7 is arranged in an "I" shape. The side edge of the end of the clamping part 2 7 near the turntable 8 is chamfered. The clamping part 2 7 can move linearly by being restricted by the limiting block 6. The side edge is chamfered so that when the turntable 8 rotates, it fits the clamping part 2 7 and pushes the clamping part 2 7 to move.
[0026] The middle part of the clamping part 2 is recessed. When the pin 3 is inserted into the slot 101, its highest point is not higher than the top surface of the clamping part 2. One clamping part 2 can be limited by two pins 3, which can prevent the pin 3 from being too high and affecting the processing of the stop block, and at the same time facilitates the removal and placement of the pin 3.
[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
