Description

Technical Field

[0001] This utility model belongs to the field of fixed tooling technology, specifically relating to a fixed tooling for tapping the cylinder body of a tooling cylinder. Background Technology

[0002] A piston cylinder is a sealed pressure vessel (usually pneumatic or hydraulic) consisting of a cylinder body, piston, connecting rod, and front and rear end caps. Threaded holes on both sides of the cylinder body are used to screw in long bolts. These long bolts pass through the open holes on the front end cap (or rear end cap) and are screwed into the threaded holes on both sides of the cylinder body, thereby simultaneously tightening and fixing the front and rear end caps to the cylinder body to seal the inside of the cylinder, withstand the working pressure, and guide the piston rod movement.

[0003] Traditional tooling typically uses a simple clamping structure to fix the cylinder body, ensuring relative stability when tapping one side of the cylinder. However, once one side is tapped and machining of the other side is required, the operator must remove the cylinder body from the tooling, readjust its position, and reinstall it. During this process, each installation requires calibration to ensure the cylinder body's positional accuracy in the machining coordinate system, meeting the accuracy requirements of the tapping.

[0004] This method of disassembling, reassembling, and calibrating twice not only consumes a lot of time and manpower, but also inevitably introduces errors during the multiple disassembly, reassembly, and calibration processes, affecting the machining accuracy of the cylinder block.

[0005] Therefore, in order to solve the above problems, it is necessary to design a fixed tooling for tapping the cylinder body of the tapping cylinder. Utility Model Content

[0006] The purpose of this invention is to provide a fixed fixture for tapping the cylinder body of a tapping cylinder, so as to solve the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a fixing fixture for tapping the cylinder body of a tapping cylinder, comprising:

[0008] A flat-jaw vise and a rotating mechanism located at the bottom of the flat-jaw vise; wherein

[0009] The flat-jaw vise is suitable for fixing the cylinder body;

[0010] The rotating mechanism is adapted to drive the flat-jaw vise to rotate.

[0011] Furthermore, the rotating mechanism includes: a base plate, a rotating shaft, a bearing sleeve fitted onto the lower part of the rotating shaft, and a support plate disposed on the top of the rotating shaft; wherein

[0012] The bottom plate has a clearance section in the middle;

[0013] The rotating shaft is located inside the clearance section and is connected to the bearing sleeve bearing;

[0014] The bearing sleeve is fixed to the bottom of the base plate;

[0015] The flat-jaw vise is fixed to the support plate; and

[0016] The rotating shaft is adapted to drive the support plate to rotate when rotating, so that the flat-jaw vise can rotate.

[0017] Furthermore, the rotating mechanism further includes: an L-plate disposed on the base plate, a telescopic member disposed on the L-plate, a gear sleeved on the upper part of the rotating shaft, and at least one transmission assembly; wherein

[0018] The transmission assembly includes: a rack that meshes with a gear;

[0019] One end of the rack is connected to the telescopic end of the telescopic component; and

[0020] The telescopic component is adapted to drive the rack to move during telescoping, and the rack meshes with the gear so that the gear drives the shaft to rotate.

[0021] Furthermore, the transmission assembly also includes: a slide rail mounted on the base plate, a slider slidably connected to the slide rail, and a mounting base mounted on the top of the slider; wherein

[0022] The rack is mounted on the mounting base;

[0023] The telescopic end of the telescopic component is connected to the mounting base.

[0024] Furthermore, the flat-jaw vise includes: a base mounted on a support plate, a fixed jaw body mounted on the base, and a movable jaw body slidably connected to the fixed jaw body; wherein

[0025] The movable clamping body grips the cylinder when it approaches the fixed clamping body.

[0026] Furthermore, the middle part of the fixing clamp body is provided with a groove;

[0027] The bottom of the movable clamp body is provided with a protrusion;

[0028] The flat-jaw vise further includes: a screw located within the slot; wherein

[0029] The screw passes through the protrusion and is threadedly connected to the protrusion;

[0030] The screw passes through the fixed clamp body and is connected to the fixed clamp body bearing.

[0031] Furthermore, one end of the screw is provided with a rotating part.

[0032] Furthermore, the flat-jaw vise also includes: two pads; wherein

[0033] The two pads are respectively fixed on the opposite surfaces of the fixed clamp body and the movable clamp body.

[0034] The beneficial effects of this utility model are:

[0035] (I) When tapping is required on the other side of the cylinder, the telescopic component is activated. The telescopic end of the component extends, causing the mounting base and the connected slider to slide on the slide rail. The sliding of the slider causes the rack to move along the direction of the slide rail. Since the rack meshes with the gear sleeved on the upper part of the rotating shaft, the linear motion of the rack is converted into the rotational motion of the gear. The rotation of the gear causes the rotating shaft to rotate in the bearing sleeve, which in turn causes the flat vise and the cylinder fixed therein to rotate together through the support plate. When the cylinder rotates to the required angle, the telescopic component stops. At this time, the cylinder has been adjusted to the appropriate processing position, and the tapping operation on the other side can be performed. Through the above description, the cylinder angle can be adjusted without disassembling the cylinder, which greatly reduces the time for disassembly, installation and calibration, and improves processing efficiency and accuracy.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0049] like Figures 1 to 6 As shown, this embodiment provides a fixing fixture for tapping the cylinder body of a tapping cylinder, including:

[0050] A flat-jaw vise 1 and a rotating mechanism 2 disposed at the bottom of the flat-jaw vise 1; wherein the flat-jaw vise 1 is adapted to fix the cylinder body; the rotating mechanism 2 is adapted to drive the flat-jaw vise 1 to rotate; wherein by fixing the cylinder body 1 with the flat-jaw vise 1 and then driving the flat-jaw vise 1 to rotate with the rotating mechanism 2, it is possible to tap both sides of the cylinder body with only one disassembly and calibration, which greatly improves the processing efficiency.

[0051] The rotating mechanism 2 includes: a base plate 21, a rotating shaft 22, a bearing sleeve 23 fitted on the lower part of the rotating shaft 22, and a support plate 24 set on the top of the rotating shaft 22; wherein the base plate 21 has a clearance part 211 in the middle; the rotating shaft 22 is located in the clearance part 211 and is connected to the bearing sleeve 23 by a bearing; the bearing sleeve 23 is fixed to the bottom of the base plate 21; the flat-jaw vise 1 is fixed on the support plate 24; and the rotating shaft 22 is adapted to drive the support plate 24 to rotate when rotating, so that the flat-jaw vise 1 can rotate; wherein the clearance part 211 is used to avoid the rotating shaft 22, preventing the base plate 21 from affecting the normal rotation of the rotating shaft 22; wherein the bearing sleeve 23 is equipped with a bearing, so that the rotating shaft 22 reduces the rotational resistance, ensuring that the rotating shaft 22 rotates smoothly and stably.

[0052] The rotating mechanism 2 further includes: an L-plate 25 disposed on the base plate 21, a telescopic member 26 disposed on the L-plate 25, a gear 27 sleeved on the upper part of the rotating shaft 22, and at least one transmission assembly 28; wherein the transmission assembly 28 includes: a rack 281 meshing with the gear 27; one end of the rack 281 is connected to the telescopic end of the telescopic member 26; and the telescopic member 26 is adapted to drive the rack 281 to move during telescopic movement, the rack 281 meshing with the gear 27, so that the gear 27 drives the rotating shaft 22 to rotate; wherein the L-plate 25 is fixed on the base plate 21 for mounting A telescopic component 26 is installed, wherein the L-plate 25 has a through hole to avoid the telescopic end of the telescopic component 26; the telescopic component 26 is, but is not limited to, a cylinder, a hydraulic cylinder, or an electric push rod; the telescopic component 26 is preferably a cylinder, and when the rack 281 meshes with the gear 27, the gear 27 rotates only 180 degrees through the full extension and full retraction of the cylinder; by setting the rack 27, under the drive of the telescopic component 26, the rack 27 moves in a straight line, and through the meshing transmission with the gear 27, the linear motion is converted into the rotational motion of the gear 27, thereby causing the rotating shaft 22 to rotate.

[0053] The transmission assembly 28 further includes: a slide rail 282 disposed on the base plate 21, a slider 283 slidably connected to the slide rail 282, and a mounting base 284 disposed on the top of the slider 283; wherein the rack 281 is mounted on the mounting base 284; the telescopic end of the telescopic member 26 is connected to the mounting base 284; wherein by setting the slide rail 282, the slider 283 and the mounting base 284, the rack 281 is fixed to the slider 283 by the mounting base 284, and the slider 283 slides on the slide rail 282, so that the rack 281 can move smoothly along the direction of the slide rail 282, thereby reducing the shaking and deviation during the movement and improving the accuracy and stability of the transmission.

[0054] In this embodiment, when tapping is required on the other side of the cylinder, the telescopic component 26 is activated, and the telescopic end of the telescopic component 26 extends, causing the mounting base 284 and the slider 283 connected thereto to slide on the slide rail 282. The sliding of the slider 283 causes the rack 281 to move along the direction of the slide rail 282. Since the rack 281 meshes with the gear 27 sleeved on the upper part of the rotating shaft 22, the linear motion of the rack 281 is converted into the rotational motion of the gear 27. The rotation of the gear 27 causes the rotating shaft to rotate in the bearing sleeve 23, which in turn causes the flat vise 1 and the cylinder fixed therein to rotate together through the support plate 24. When the cylinder rotates to the required angle, the telescopic component 26 stops. At this time, the cylinder has been adjusted to a suitable processing position, and the tapping operation on the other side can be performed. Through the above description, the cylinder angle can be adjusted without disassembling the cylinder, which greatly reduces the time for disassembly, installation and calibration, and improves processing efficiency and accuracy.

[0055] The flat-jaw vise 1 includes: a base 11 disposed on a support plate 24, a fixed jaw 12 disposed on the base 11, and a movable jaw 13 slidably connected to the fixed jaw 12; wherein the movable jaw 13 clamps the cylinder when it is close to the fixed jaw 12.

[0056] The fixed clamp body 12 has a groove 121 in the middle; the movable clamp body 13 has a protrusion 131 at the bottom; the flat-jaw vise 1 also includes a screw 14 located in the groove 121; wherein the screw 14 passes through the protrusion 131 and is threadedly connected to the protrusion 131; the screw 14 passes through the fixed clamp body 12 and is bearing-connected to the fixed clamp body 12; wherein the protrusion 131 is threadedly connected to the screw 14, and the rotation of the screw 14 drives the movable clamp body 13 to move closer to or away from the fixed clamp body 12, thereby realizing the clamping and releasing of the cylinder.

[0057] One end of the screw 14 is provided with a rotating part 141; wherein the cross section of the rotating part 141 is preferably a double polygon (such as a quadrilateral, hexagon, octagon, etc.) so as to be compatible with the wrench and facilitate the operator to rotate the screw 14.

[0058] The flat-jaw vise 1 further includes two pads 15; wherein the two pads 15 are respectively fixed on the opposite surfaces of the fixed vise body 12 and the movable vise body 13; wherein the pads 15 are preferably made of wood, so as to avoid damaging the surface of the cylinder body when the movable vise body 13 approaches the fixed vise body 12 to clamp the cylinder body.

[0059] In this embodiment, when it is necessary to fix the tapping cylinder body, the operator first places the cylinder body between the fixed jaw 12 and the movable jaw 13 of the flat-jaw vise. Then, by rotating the rotating part 141 of the screw 14, the screw 14 is rotated. Since the screw 14 is threadedly connected to the protrusion 131 at the bottom of the movable jaw 13, the rotation of the screw 14 will cause the movable jaw 13 to slide along the fixed jaw 12 and gradually approach the fixed jaw 12, thereby clamping the cylinder body between the two. At this time, the pads 15 on the fixed jaw 12 and the movable jaw 13 are in contact with the surface of the cylinder body, increasing the friction and protecting the surface of the cylinder body. By adjusting the number of rotations of the screw 14, the clamping force is controlled to ensure that the cylinder body is firmly fixed and will not be displaced during the tapping process.
