Description

Technical Field

[0001] This invention relates to the field of electric actuator processing, and more particularly to a clamping fixture for die-cast housings of electric actuators. Background Technology

[0002] In electric actuators, the housing is the main supporting component, and the overall machining accuracy of the housing directly affects the performance of the electric actuator. If the housing is not accurately positioned, it will directly lead to a very low yield rate and reduce product quality.

[0003] Because each batch of die-cast blanks (i.e., the box body) has different die-cast shapes, the existing box body machining tooling has poor adaptability and lacks a self-centering mechanism, making adjustment inconvenient. At the same time, one set of tooling can only process one box body, resulting in low efficiency. Summary of the Invention

[0004] To address the above problems, this invention provides a simple, easily adjustable, and efficient clamping fixture for die-cast housings of electric actuators.

[0005] The technical solution of the present invention is: a clamping fixture for a die-cast housing of an electric actuator, comprising a pallet, wherein a clamping assembly is provided on the pallet. The clamping assembly includes a base, a centering mechanism, and a pair of clamping mechanisms. The base is placed on the tray. The base is stepped, with a smaller top and a larger bottom, and includes an upper body and a lower body. The top surface of the upper body is used to place the box. The box has a through hole in the vertical direction, including a positioning hole at the bottom and a through hole at the top. The two ends of the box are respectively provided with reinforcing ribs, wherein one reinforcing rib is located below the machining hole at one end of the box. A pair of clamping mechanisms are arranged opposite each other and located at both ends of the base. The clamping mechanisms correspond one-to-one with the reinforcing ribs and are used to clamp the reinforcing ribs. The clamping mechanism includes a base, a clamping screw, a clamping movable block, and a pair of clamping blocks. The base is mounted on a tray and located at one end of the lower body. The base has a receiving groove, and the clamping movable block is located in the receiving groove. The clamping movable block has a through horizontal hole with a cross-shaped cross section. The clamping screw has an annular boss in the middle and is located in the horizontal hole. A pair of clamping blocks are located on the top surface of the base and on both sides of the clamping movable block. The pair of clamping blocks are respectively connected to the clamping screw through threads. The pair of clamping blocks are used to clamp the reinforcing ribs. One of the clamping mechanisms is equipped with an adjustment group, which is used to adjust the direction and clamping of the pressing movable block; The centering mechanism is located between a pair of clamping mechanisms and is used to center the positioning hole of the housing.

[0006] The adjustment assembly includes a pair of wedges and a pair of screws. The pair of wedges are respectively disposed in the receiving groove and located on both sides of the pressing movable block. The outer ends of the wedges are provided with mounting grooves. A pair of screws are threadedly connected to the base and located on both sides of the pressing movable block. The screws and wedges correspond one to one. The outer end of the screw is provided with an insert, which is used to connect in the mounting groove.

[0007] The clamping block is 7-shaped and includes a vertically arranged upright block and a clamping block located on one side of the top of the upright block. The upright block is threadedly connected to the clamping screw. A pair of clamping blocks are used to clamp the reinforcing ribs.

[0008] The upright block and clamping block are integrally formed or connected by bolts.

[0009] The centering mechanism includes a rotating rod, a steering block, a transmission rod, a moving ring, and three sets of pressure wheels. The upper seat has a mounting hole in the middle and a sliding hole communicating with the mounting hole on one side; One end of the rotating rod is connected to the tray via a support base, and the other end is connected to the steering block via a thread. The transmission rod is located in the sliding hole and is connected to the moving ring. The moving ring and the clamping wheel assembly are respectively disposed in the mounting hole. The outer ring of the moving ring has three notches on its circumference. The clamping wheel assembly is disposed in the notches one by one. The clamping wheel assembly includes a rocker plate and a pair of clamping wheels. The rocker plate is movably connected to the mounting hole through a support column. The two ends of the rocker plate are respectively provided with U-shaped grooves with outward openings. The clamping wheels are movably connected in the U-shaped grooves. In the vertical direction, the rocker plate is located above the top surface of the upper body.

[0010] The inner ring of the moving ring is provided with a retaining ring on its circumference, and the mounting hole is provided with an annular protrusion, which is located inside the moving ring and is used to support the retaining ring. It also includes a positioning disk, which is connected to the mounting hole and located in the moving ring. The bottom outer ring of the positioning disk is provided with a positioning ring groove, and the retaining ring is located in the positioning ring groove.

[0011] It also includes a baffle through which the transmission rod passes, the baffle being used to conform to and cover the sliding hole.

[0012] It also includes a column, which is connected to the upper body. The column is used to pass through the through hole and a pressure plate is connected to it. The pressure plate is used to press against the top through hole of the box.

[0013] It also includes a column connected to the upper body; the box body has a cylinder located in the through hole, the column passes through the cylinder, and a pressure plate is connected to the column, which is used to press on the top of the cylinder.

[0014] The clamping assembly comprises two.

[0015] In operation, the positioning holes of the housing are placed on the upper base, and the reinforcing ribs correspond one-to-one with the clamping mechanism and are located between a pair of clamping blocks of the clamping mechanism; the specific clamping process is as follows: First, the housing is initially centered using a centering mechanism; second, the reinforcing ribs are adjusted and clamped using a clamping assembly that includes an adjustment group; then, the centering mechanism re-centers the housing. Finally, another clamping component clamps the corresponding reinforcing rib.

[0016] Because the wall thickness on both sides of the machined hole in the housing is inconsistent, the angle of the housing needs to be adjusted to ensure the consistency of the wall thickness on both sides of the machined hole during subsequent processing. The function of the adjustment group is to adjust the angle of the housing and, through limiting, ensure that the direction of the reinforcing ribs is consistent during processing of a batch of blanks, thereby ensuring the consistency of the housing surface quality.

[0017] After the clamping assembly containing the adjustment group clamps the corresponding reinforcing rib, another clamping assembly uses an automatic angle adjustment method to avoid over-positioning caused by casting errors of the reinforcing ribs on both sides of the box blank. The operation of the other clamping assembly is as follows: when the clamping screw is rotated, it drives a pair of clamping blocks to move. When the clamping blocks contact the reinforcing ribs of the box, the reaction force will automatically adjust the direction of the clamping moving blocks until the clamping action is completed.

[0018] This invention is easy to process and reliable to operate. Attached Figure Description

[0024] The present invention is as follows Figure 1-14 As shown, a clamping fixture for a die-cast housing of an electric actuator includes a tray 1, on which clamping components are provided. The clamping assembly includes a base 2, a centering mechanism 3, and a pair of clamping mechanisms 4. The base 2 is mounted on the tray 1. The base 2 is stepped, with a smaller top and a larger bottom, and includes an upper body 21 and a lower body 22. The top surface of the upper body is used to place the box 5. The box has a through hole in the vertical direction, including a positioning hole 51 at the bottom and a through hole 52 at the top. The two ends of the box are respectively provided with reinforcing ribs 53, wherein one reinforcing rib is located below the machining hole 54 at one end of the box. A pair of clamping mechanisms 4 are arranged opposite each other and located at both ends of the base 2. The clamping mechanisms 4 correspond one-to-one with the reinforcing ribs 53 and are used to clamp the reinforcing ribs. The clamping mechanism 4 includes a base 41, a clamping screw 42, a clamping movable block 43, and a pair of clamping blocks 44. The base 41 is mounted on the tray 1 and located at one end of the lower seat 22. The base 41 has a receiving groove 410. The clamping movable block 43 is located in the receiving groove 410. The clamping movable block 43 has a through horizontal hole 430. The cross-section of the horizontal hole is cross-shaped. The clamping screw 42 has an annular boss 420 in the middle (thus forming a cross shape). The clamping screw is located in the horizontal hole. A pair of clamping blocks 44 are provided on the top surface of the base 41 and located on both sides of the clamping movable block 43. The pair of clamping blocks 44 are respectively connected to the clamping screw 42 by threads. The outer end of the clamping screw is provided with a hand-held part for easy hand operation. The pair of clamping blocks 44 are used to clamp the reinforcing rib 53. The clamping screw includes reversed threads on both sides and an annular boss in the middle. The annular boss is used to adjust the angle with the clamping movable block, and the threads on both sides are used to drive the movement of a pair of clamping blocks connected to it during rotation.

[0025] One of the clamping mechanisms is equipped with an adjustment group 6, which is used to adjust the direction and clamping of the pressing movable block 43; The centering mechanism 3 is located between a pair of clamping mechanisms 4, and the centering mechanism is used to center the positioning hole 5 of the box.

[0026] In operation, the positioning holes of the housing are placed on the upper base, and the reinforcing ribs correspond one-to-one with the clamping mechanism and are located between a pair of clamping blocks of the clamping mechanism; the specific clamping process is as follows: First, the housing is initially centered using a centering mechanism; second, the reinforcing ribs are adjusted and clamped using a clamping assembly that includes an adjustment group; then, the centering mechanism re-centers the housing. Finally, another clamping component clamps the corresponding reinforcing rib.

[0027] Because the wall thickness on both sides of the machined hole in the housing is inconsistent, the angle of the housing needs to be adjusted to ensure the consistency of the wall thickness on both sides of the machined hole during subsequent processing. The function of the adjustment group is to adjust the angle of the housing and, through limiting, ensure that the direction of the reinforcing ribs is consistent during processing of a batch of blanks, thereby ensuring the consistency of the housing surface quality.

[0028] After the clamping assembly containing the adjustment group clamps the corresponding reinforcing rib, another clamping assembly uses an automatic angle adjustment method to avoid over-positioning caused by casting errors of the reinforcing ribs on both sides of the box blank. The operation of the other clamping assembly is as follows: when the clamping screw is rotated, it drives a pair of clamping blocks to move. When the clamping blocks contact the reinforcing ribs of the box, the reaction force will automatically adjust the direction of the clamping moving blocks until the clamping action is completed.

[0029] The adjustment assembly includes a pair of wedges 61 and a pair of screws 62. The pair of wedges 61 are respectively disposed in the receiving groove 410 and located on both sides of the pressing movable block. The outer end of the wedge is provided with a mounting groove 610. A pair of screws 62 are threadedly connected to the base and located on both sides of the pressing movable block. The screws 62 and wedges 61 correspond one-to-one. The outer end of the screw is provided with an insert 63, which is used to connect in the mounting groove 610.

[0030] By loosening one screw, the corresponding wedge block moves outward. At this time, the pressing movable block is not completely fixed. By tightening the other screw, the corresponding wedge block moves inward, and the pressing movable block is fixed. As the pressing block rotates, the pressing screw engages with the pressing block (i.e., the cross-shaped pressing screw is located in the cross-shaped horizontal hole), and the pressing screw will also move. By rotating the pressing screw, a pair of pressing blocks move simultaneously, thereby driving the box to rotate.

[0031] The clamping block 44 is 7-shaped and includes a vertically arranged upright block 441 and a clamping block 442 located on one side of the top of the upright block. The upright block 441 is threadedly connected to the clamping screw 42. A pair of clamping blocks 442 are used to clamp the reinforcing ribs.

[0032] A figure-seven shaped clamping block is installed to meet the clamping space requirements of the reinforcing ribs and ensure clamping reliability. Under the action of the clamping screw, the upright block moves, and the clamping block performs the clamping action.

[0033] The upright block 441 and the clamping block 442 are integrally formed or connected by bolts.

[0034] During processing, the upright block and clamping block can be integrally formed or connected separately. When connected separately, the clamping block can be connected to the upright block by bolts, which is convenient for disassembly and assembly, and facilitates the replacement of clamping blocks of different specifications, thus improving adaptability.

[0035] The centering mechanism includes a rotating rod 31, a steering block 32, a transmission rod 33, a moving ring 34, and three sets of pressure wheel sets 35. The upper seat has a mounting hole 210 in the middle and a sliding hole 211 communicating with the mounting hole on one side; One end of the rotating rod 31 is connected to the tray via the support base 36, and the other end is connected to the steering block 32 via a thread. The transmission rod 33 is located in the sliding hole 211 and is connected to the moving ring 34. The moving ring 34 and the clamping wheel assembly 35 are respectively disposed in the mounting hole 210. The outer ring of the moving ring 34 has three notches 340 on its circumference. The clamping wheel assembly 35 is disposed in the notches 340 in a corresponding manner. The clamping wheel assembly 35 includes a rocker plate 351 and a pair of clamping wheels 352. The rocker plate is movably connected to the mounting hole 210 through a support column 353. The two ends of the rocker plate are respectively provided with U-shaped grooves 354 with outward openings. The clamping wheels 352 are movably connected to the U-shaped grooves 354. In the vertical direction, the rocker plate is located above the top surface of the upper body.

[0036] A centering mechanism is designed to achieve self-centering of the blank. By rotating the rotating rod, the steering block receives a clockwise thrust, which is transmitted to the transmission rod, which in turn transmits the force to the moving ring. The moving ring, under this force, rotates clockwise. During this rotation, the clamping wheel assembly begins to rotate, with the right clamping wheel moving outwards and the left clamping wheel moving inwards. The right clamping wheel in each assembly presses against the inner hole of the blank, thus centering the blank. When the blank is clamped, the moving ring is located within the positioning hole of the blank. Under normal conditions, the rocker plate and clamping wheels are located within the notch; during the centering action, the clamping wheels extend out of the notch.

[0037] The inner ring of the moving ring is provided with a retaining ring 341 on the circumference, and the mounting hole is provided with an annular protrusion 212. The annular protrusion 212 is located inside the moving ring and is used to support the retaining ring 341. It also includes a positioning disk 37, which is connected within the mounting hole 210 and located within the moving ring 34. The bottom outer ring of the positioning disk 37 is provided with a positioning ring groove 370, and the retaining ring 341 is located within the positioning ring groove 370. The positioning disk and the upper body are connected by screws.

[0038] An annular protrusion is provided to reliably position and support the retaining ring, facilitating the positioning of the moving ring; a positioning disc is provided to further position the retaining ring through the positioning ring groove; in this way, reliable positioning of the moving ring is achieved while ensuring its rotation.

[0039] It also includes a baffle 38 through which the transmission rod 33 passes, and the baffle 38 is used to fit and cover the sliding hole 211.

[0040] A baffle is installed to cover the sliding hole, which helps to prevent aluminum chips and other materials from entering the hole and improves the quality of the processing environment.

[0041] It also includes a column 7, which is connected to the upper body and is located in the middle hole of the positioning plate. The column is used to pass through the through hole and a pressure plate 8 is connected to the column. The pressure plate 8 is used to press on the top through hole of the box.

[0042] The first auxiliary clamping solution is as follows: When it is found that the box cannot be completely fixed and there is local vibration during the processing of the box, the box can be clamped by the upper pressure plate to implement auxiliary clamping.

[0043] It also includes a column 7, which is connected to the upper body and is located in the center hole of the positioning plate; The box contains a cylindrical body 55, which is located inside a through hole. The column passes through the cylindrical body and is used to connect a pressure plate 9, which is used to press on the top of the cylindrical body.

[0044] When the auxiliary clamping scheme one causes deformation of the box body's processing dimensions, auxiliary clamping scheme two can be used for clamping. Specifically, the box body is clamped by the pressure plate two in the middle of the box body to implement auxiliary clamping.

[0045] The clamping assembly comprises two.

[0046] This allows for two workstations to be set up, clamping two boxes for processing, thus improving efficiency.

[0047] By making full use of the space above the pallet, a normal horizontal machining center can complete the processing of two workstations at once, saving pallet space.
