Description

Technical Field

[0001] This invention relates to the field of clamping fixture technology, specifically to a horizontal clamping fixture and clamping method for thin-walled rotating parts. Background Technology

[0002] The horizontal clamping fixture for thin-walled rotating parts is mainly used for machining, positioning and fixing thin-walled circular workpieces. During the machining process, it ensures that the thin-walled parts will not move or deform, so as to maintain machining accuracy. Through reasonable design, it ensures that the workpiece is accurately placed in the machining center and avoids machining errors caused by position deviation.

[0003] Existing horizontal clamping fixtures for thin-walled rotating parts present difficulties in quickly positioning and clamping the parts, affecting work efficiency. Traditional clamping fixture designs lack flexibility, requiring significant time for adjustment and positioning when changing workpieces. Each clamping requires manual adjustment, which is prone to errors and increases operational complexity. This not only delays production but may also result in low workpiece machining accuracy and increased workload for subsequent finishing.

[0004] Therefore, the present invention provides a horizontal clamping fixture and clamping method for thin-walled rotating parts. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a horizontal clamping fixture and clamping method for thin-walled rotating parts.

[0006] The technical solution of the present invention is: a horizontal clamping fixture for thin-walled rotating parts, comprising a base plate and at least two sets of side wall clamping mechanisms disposed on the base plate for clamping the side walls of the thin-walled rotating parts. The base plate is provided with front and rear clamping mechanisms for front and rear limiting of the thin-walled rotating parts and a snap-fit ​​mechanism for assisting in fixing the thin-walled rotating parts.

[0007] The sidewall clamping mechanism consists of a base with an arc-shaped groove and an arc-shaped plate. The base is mounted on the bottom plate, and one end of the arc-shaped plate is hinged to a fixing rod located on one side of the bottom plate. The other end of the arc-shaped plate is detachably connected to a connecting rod located on the other side of the bottom plate. Both the base and the arc-shaped plate are equipped with a second cylinder and a limiting rod fixedly connected to the output end of the second cylinder.

[0008] The front and rear clamping mechanism consists of a stop block located at one end of the base plate, a first cylinder located at the other end of the base plate, and a push block fixedly connected to the output end of the first cylinder.

[0009] Furthermore, the connecting rod is provided with a connecting assembly, which includes a bolt rotatably connected to the connecting rod and a limiting nut threadedly connected to the bolt, and the arc plate has a groove for the bolt to be engaged.

[0010] Note: Bolt and nut connection is simple and stable.

[0011] Furthermore, the latching mechanism is provided in two sets and symmetrically arranged on the base plate on both sides of the thin-walled rotating body part. The latching mechanism includes a third cylinder set on the base plate and a latching block for fixing the hole on the thin-walled rotating body part. One end of the latching block is hinged to the output end of the third cylinder. A limiting plate is provided on the base plate or the third cylinder, and one end of the latching block is hinged to the limiting plate through a hinge rod.

[0012] Description: The third cylinder drives the locking block to rotate towards the thin-walled rotating part under the hinge action of the third cylinder and the limiting plate, thereby extending into the hole and fixing and limiting the hole. The operation is simple.

[0013] Furthermore, the other end of the card block is provided with a card head for fixing the holes on the thin-walled rotating part.

[0014] Note: The clip is designed to help the clip secure the hole.

[0015] Furthermore, both the locking block and the limiting rod are covered with a rubber layer.

[0016] Note: The rubber layer prevents the locking blocks and limit rods from damaging the surface of the thin-walled rotating parts.

[0017] Furthermore, each of the said arc-shaped plates has a handle.

[0018] Note: Handles are provided to facilitate the movement of the entire clamping device.

[0019] Furthermore, the latching mechanism is provided on a base plate located directly below the thin-walled rotating part. The latching mechanism includes an arc-shaped support base fixedly connected to the base plate, multiple airbag rods disposed on the arc-shaped support base for fixing the holes on the thin-walled rotating part, and an airbag canister disposed between the base and the push block. The arc-shaped support base is hollow inside and communicates with the airbag canister. The arc-shaped support base consists of an arc-shaped support box fixedly connected to the base plate and an arc-shaped movable plate slidably and sealingly connected to the arc-shaped support box. The arc-shaped movable plate is connected to the bottom of the arc-shaped support box by a first spring. The multiple airbag rods are evenly distributed on the arc-shaped movable plate and fixedly connected to the arc-shaped movable plate, and all multiple airbag rods communicate with the interior of the arc-shaped support base through air ports.

[0020] The airbag rod is provided with a trigger rod inside, which is arranged along the length of the airbag rod. One end of the trigger rod extends out of the end of the airbag rod and is provided with a trigger block. The other end of the trigger rod extends into the arc-shaped support base. A cover plate is fixed on the trigger rod for controlling the opening or closing of the air vent by sliding the trigger rod. A second spring is sleeved on the trigger rod located between the trigger block and the airbag rod.

[0021] Explanation: By using the front and rear limiting operation of the thin-walled rotating body part, the air bladder canister is squeezed, which automatically drives the air bladder rod on the arc-shaped support to extend into the hole of the thin-walled rotating body part to fix and limit the hole part. The air bladder rods on the non-hole parts of the surface of the thin-walled rotating body part will automatically trigger the deflation and close the air intake of the part under the action of the trigger block and the second spring after contacting the surface of the thin-walled rotating body part, thereby relieving the pressure generated on the surface of the thin-walled rotating body part, and eliminating the need for additional electrical control equipment to fix and limit the hole.

[0022] Furthermore, the top of the airbag rod is provided with a liquid bladder containing lubricating fluid, the trigger block is hollow inside and communicates with the liquid bladder, the top of the trigger block is provided with a liquid outlet hole, and a pressure valve for opening or closing the liquid outlet hole is provided on the liquid outlet hole.

[0023] Explanation: The liquid bladder is designed so that the trigger block that contacts the surface of the thin-walled rotating part can lubricate the surface of the thin-walled rotating part, thereby reducing damage to the thin-walled rotating part.

[0024] A clamping method for a horizontal clamping fixture for a thin-walled rotating part according to any one of the above claims includes the following steps:

[0025] S1. Preliminary positioning of the thin-walled rotating part:

[0026] Place the thin-walled rotating part on the base, and then connect the other end of the arc plate to the connecting rod to complete the initial positioning.

[0027] S2. Front and rear limits of thin-walled rotating parts:

[0028] The first cylinder is driven to move the push block, thereby clamping and fixing the thin-walled rotating part with the stop block, and completing the front and rear limit;

[0029] S3. Side wall limiting of thin-walled rotating parts:

[0030] Drive the second cylinder to extend the limit rod to the side wall of the fixed thin-walled rotating part, thus completing the side wall limiting;

[0031] S4. Hole limiting for thin-walled rotating parts:

[0032] The clamping mechanism is used to fix and limit the holes on the thin-walled rotating parts, thus completing the clamping.

[0033] The beneficial effects of this invention are:

[0034] (1) When the clamping fixture of the present invention is used, after the thin-walled rotating part is placed on the base, the arc plate is fixed. The first cylinder will drive the push block to move, so that the push block and the stop block limit the front and rear of the thin-walled rotating part. Then the second cylinder will drive the limit rod to move, which limits the side wall of the thin-walled rotating part. Then the third cylinder will drive the clamping block to limit the hole on the thin-walled rotating part, thereby achieving the purpose of multi-directional rapid clamping of the thin-walled rotating part and improving work efficiency.

[0035] (2) The clamping fixture of the present invention utilizes the operation of front and rear limiting of the thin-walled rotating body part to squeeze the air bag canister, thereby automatically driving the air bag rod on the arc support seat to extend into the hole of the thin-walled rotating body part to fix and limit the hole part. The air bag rod corresponding to the non-hole part of the surface of the thin-walled rotating body part will automatically trigger the deflation and close the air intake of this part of the air bag rod under the action of the trigger block and the second spring after contacting the surface of the thin-walled rotating body part, thereby relieving the pressure generated on the surface of the thin-walled rotating body part, and there is no need to use additional electrical control equipment for hole fixing and limiting.

Detailed Implementation

[0046] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0047] Example 1: A horizontal clamping fixture for thin-walled rotating parts, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a base plate 1 and three sets of side wall clamping mechanisms disposed on the base plate 1 for clamping the side walls of the thin-walled rotating body parts. The bottom of the base plate 1 is provided with a mounting plate. The base plate 1 is provided with front and rear clamping mechanisms for front and rear limiting of the thin-walled rotating body parts and a buckling mechanism for assisting in fixing the thin-walled rotating body parts.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, the sidewall clamping mechanism consists of a base 4 with an arc-shaped groove and an arc-shaped plate 41. The base 4 is mounted on a base plate 1. One end of the arc-shaped plate 41 is hinged to a fixing rod 42 located on one side of the base 4 on the base plate 1. The other end of the arc-shaped plate is detachably connected to a connecting rod 43 located on the other side of the base 4 on the base plate 1. Both the base 4 and the arc-shaped plate 41 are equipped with a second cylinder 45 and a limiting rod 44 fixedly connected to the output end of the second cylinder 45. The connecting rod 43 is equipped with a connecting assembly, which includes a bolt 431 rotatably connected to the connecting rod 43 and a limiting nut 432 threadedly connected to the bolt 431. The arc-shaped plate 41 has a groove for engaging the bolt 431. One of the arc-shaped plates 41 has a handle.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the front and rear clamping mechanism consists of a stop block 2 disposed at one end of the base plate 1, a first cylinder 22 disposed at the other end of the base plate 1, and a push block 21 fixedly connected to the output end of the first cylinder 22.

[0050] like Figure 3 and Figure 4As shown, the latching mechanism has two sets symmetrically arranged on the base plate 1 located on both sides of the thin-walled rotating body part. The latching mechanism includes a third cylinder 3 arranged on the base plate 1 and a latching block 31 for fixing the hole on the thin-walled rotating body part. One end of the latching block 31 is hinged to the output end of the third cylinder 3. The third cylinder 3 is provided with a limiting plate 32, and one end of the latching block 31 is hinged to the limiting plate 32 through a hinge rod. The other end of the latching block 31 is provided with a latch head for fixing the hole on the thin-walled rotating body part.

[0051] The first cylinder 22, the second cylinder 45 and the third cylinder 3 are all commercially available equipment, and the locking block 31 and the limiting rod 44 are all wrapped with a rubber layer.

[0052] The method for clamping thin-walled rotating parts using the above-mentioned horizontal clamping fixture includes the following steps:

[0053] S1. Preliminary positioning of the thin-walled rotating part:

[0054] Place the thin-walled rotating part on the base 4, with the rear side of the thin-walled rotating part abutting against the stop block 2. Then connect the other end of the arc plate 41 to the connecting rod 43 on the base plate 1 through bolts 431 and limit nuts 432 to complete the initial limiting.

[0055] S2. Front and rear limits of thin-walled rotating parts:

[0056] Drive the first cylinder 22 to move the front push block 21 toward the thin-walled rotating part, thereby clamping and fixing the thin-walled rotating part with the stop block 2, and completing the front and rear limit;

[0057] S3. Side wall limiting of thin-walled rotating parts:

[0058] Drive the second cylinder 45 to extend the limiting rod 44 on the arc plate 41 and the base 4 to the surface of the fixed thin-walled rotating part, and complete the side wall limiting;

[0059] S4. Hole limiting for thin-walled rotating parts:

[0060] Drive the third cylinder 3 to make the clamping block 31 rotate toward the surface of the thin-walled rotating part under the hinge action of the third cylinder 3 and the limiting plate 32 until the clamping head of the clamping block 31 extends into the hole and is fixed to the hole, thus completing the clamping.

[0061] Example 2: This example differs from Example 1 in that, as Figure 5 , Figure 6 and Figure 7As shown, the buckling mechanism is provided on a base plate 1 located directly below the thin-walled rotating body part. The buckling mechanism includes an arc-shaped support seat 5 fixedly connected to the base plate 1, a plurality of airbag rods 52 provided on the arc-shaped support seat 5 for fixing the holes on the thin-walled rotating body part, and an airbag canister 51 provided between the base 4 and the push block 21. The push block 21 has an extension plate that raises the contact surface between the push block 21 and the airbag canister 51.

[0062] like Figure 7 and Figure 8 As shown, the arc-shaped support base 5 is hollow inside and communicates with the airbag canister 51. The arc-shaped support base 5 consists of an arc-shaped support box 531 fixedly connected to the base plate 1 and an arc-shaped movable plate 53 slidably and sealingly connected to the arc-shaped support box 531. The arc-shaped movable plate 53 is connected to the bottom of the arc-shaped support box 531 by a first spring 54. A plurality of airbag rods 52 are evenly distributed on the arc-shaped movable plate 53 and fixedly connected to the arc-shaped movable plate 53. All the airbag rods 52 communicate with the interior of the arc-shaped support base 5 through air ports.

[0063] like Figure 7 and Figure 8 As shown, the airbag rod 52 has a trigger rod 56 arranged along the length of the airbag rod 52 inside. One end of the trigger rod 56 extends out of the end of the airbag rod 52 and is provided with a trigger block 55. The other end of the trigger rod 56 extends into the arc-shaped support base 5. A cover plate 57 for controlling the opening or closing of the air port by sliding the trigger rod 56 is fixed on the trigger rod 56. A second spring 58 is sleeved on the trigger rod 56 located between the trigger block 55 and the airbag rod 52. The compressed length of the second spring 58 is greater than the distance of the cover plate 57 from the air port when the airbag rod 52 is stretched to its maximum length by 5 cm. The distribution density of the airbag rods 52 is such that one hole of the thin-walled rotating body part can accommodate 5 airbag rods, that is, to ensure that when the hole is limited, at least one airbag rod 52 can be inserted into the hole for fixation.

[0064] The clamping method in this embodiment differs from that in Embodiment 1 in that:

[0065] S4. Hole limiting for thin-walled rotating parts:

[0066] After the thin-walled rotating part is placed on the base 4, it is also located directly above the arc-shaped support 5. During the movement of the push block 21, the airbag canister 51 is squeezed, causing gas to be released into the arc-shaped support 5 and the airbag rod 52. Then, the arc-shaped movable plate 53 of the arc-shaped support 5 moves upward and close to the thin-walled rotating part under the action of air pressure. During the upward movement of part of the airbag rod 52, air is also simultaneously introduced, driving the trigger block 55, trigger rod 56 and cover plate 57 to extend into the hole on the surface of the thin-walled rotating part, fixing and limiting the hole.

[0067] The trigger block 55 of the other part of the airbag rod 52 first contacts the surface of the thin-walled rotating body part. The trigger block 55 can no longer move. Then, under the upward movement of the arc-shaped movable plate 53, the second spring 58 is compressed first. As a result, the trigger rod 56 drives the cover plate 57 to slide to block the air port of the airbag rod 52, so that the other part of the airbag rod 52 no longer takes in air.

[0068] When the clamping is canceled, the push block 21 moves in the opposite direction, stretching the airbag canister 51 and drawing air from the arc-shaped support 5 and the airbag rod 52. The arc-shaped movable plate 53 then moves down and resets under the action of the first spring 54 and the suction force. At the same time, part of the airbag rod 52 that has been inserted into the hole is drawn in and resets. Another part of the airbag rod 52 disengages from the surface of the thin-walled rotating body part during the reset process with the arc-shaped movable plate 53. As a result, the trigger block 55 restores the distance between itself and the airbag rod 52 under the action of the second spring 58, thereby driving the trigger rod 56 and the cover plate 57 to reset and open the air port of the airbag rod 52. This part of the airbag rod 52 is also drawn in and reset, thus canceling the fixed limit on the hole on the surface of the thin-walled rotating body part.

[0069] Example 3: This example differs from Example 2 in that, as Figure 9 As shown, the top of the airbag rod 52 is provided with a liquid bladder 59 containing lubricating fluid. The liquid bladder 59 is annular. The trigger block 55 is hollow inside and communicates with the liquid bladder 59. The top of the trigger block 55 is provided with a liquid outlet hole. The liquid outlet hole is provided with a pressure valve for opening or closing the liquid outlet hole. The pressure valve is a commercially available device.

[0070] The clamping method in this embodiment differs from that in Embodiment 2 in that:

[0071] S4. Hole limiting for thin-walled rotating parts:

[0072] During the compression of the second spring 58, the liquid bladder 59 is simultaneously compressed, thereby lubricating the surface of the thin-walled rotating part through the liquid outlet of the trigger block 55 to alleviate damage to the surface of the thin-walled rotating part.
