Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to an angle scale pressing positioning tooling for an excitation block. Background Technology

[0002] Exciter block (as per the instruction manual) Figure 7 As shown), it is used to adjust the excitation force of the vibration motor. The excitation block needs to be precisely engraved with angle scale on the circumference. Currently, there are two ways to make the scale plate: ordinary riveting scale indicator plate or pasting scale indicator sticker. During the production, it mainly relies on manual visual alignment, and the error is > ±2°, which leads to a deviation of >15% in the motor excitation force.

[0003] To address this, our company has developed and manufactured a vibratory block angle scale pressing and positioning fixture, which not only ensures scale accuracy but also saves time and effort. Summary of the Invention

[0004] In response to the shortcomings of existing technologies, this utility model provides an angle scale pressing and positioning fixture for exciter blocks, which solves the problem of large errors in existing exciter block angle scale plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle scale pressing and positioning fixture for an excitation block, comprising an upper mold base and an upper mold assembly concentrically disposed with the upper mold base.

[0006] The lower mold plate, the upper mold assembly, and the axis of the lower mold plate are all provided with mold closing slots. The upper and lower mold closing slots are closed by a mold closing module.

[0007] The lower mold base is located at the bottom of the lower mold plate. The interior of the lower mold base is provided with a cavity for accommodating the guide rail positioning mechanism and a mandrel positioning mechanism. A base is installed at the bottom of the lower mold base.

[0008] A pair of clearance holes are provided on the upper horizontal direction of the lower template. A vibration block positioning and correction pin is detachably installed in the clearance hole. The vibration block positioning and correction pin is connected to the guide rail positioning mechanism and is driven by the guide rail positioning mechanism to achieve horizontal and longitudinal fine adjustment, so that the workpiece reaches the target position.

[0009] The spindle positioning mechanism positions the workpiece or facilitates the picking and placing of the workpiece by lifting and lowering it.

[0010] As a further preferred embodiment, the upper die assembly includes: a punch fixing plate, a number punch, a scale punch, and a set screw. The number punch and the scale punch are both vertically mounted on the lower plane of the punch fixing plate by the set screw, and are symmetrically arranged with the horizontal center line of the punch fixing plate as the reference.

[0011] As a further preferred embodiment, the lower mold base is composed of four irregularly shaped pads of the same shape, and the four irregularly shaped pads are simultaneously connected to the lower mold plate and the base by bolts.

[0012] As a further preferred embodiment, the guide rail positioning mechanism includes a movable positioning push plate, a push plate pad, two linear slide rail sliders, two linear slide rail guides, a hand-cranked ball screw, a handwheel, a coupling, a support end, and a nut seat.

[0013] Two linear guide rails are arranged axially parallel to the hand-cranked ball screw. The corresponding sliding slider of the linear guide rail is slidably mounted on the linear guide rail. The movable positioning push plate is threadedly connected to the hand-cranked ball screw through the nut seat at the bottom. The movable positioning push plate is provided with a hole slot for inserting the positioning and correction pin of the excitation block.

[0014] The hand-cranked ball screw is driven by turning the handwheel to move the positioning and correction pin of the excitation block within the clearance hole, thereby finely adjusting the position of the workpiece.

[0015] As a further preferred embodiment, the mandrel positioning mechanism includes a vibratory block positioning mandrel, a three-axis cylinder, a cylinder switch, and an air pipe.

[0016] The cylinder body of the three-axis cylinder passes through the mold closing groove and the cylinder clearance hole on the moving positioning push plate in sequence and is vertically installed at the center of the base.

[0017] By turning on the cylinder switch, the piston rod of the three-axis cylinder is driven to rise, which in turn drives the positioning spindle of the excitation block at the top to rise, thus positioning the workpiece; when the piston rod descends, it facilitates the picking and placing of the workpiece.

[0018] This utility model provides a positioning fixture for pressing and positioning an exciter block with an angle scale. It has the following advantages:

[0019] This exciter block angle scale pressing and positioning fixture, through the setting of a guide rail positioning mechanism, can automatically make the exciter block and the upper mold assembly accurately aligned, thereby achieving fast and accurate scale pressing work.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7 As shown, this utility model provides a technical solution: an angle scale pressing and positioning tooling for an excitation block, including an upper mold base 1 and an upper mold assembly 2 concentrically arranged with the upper mold base 1.

[0030] The upper die assembly 2 includes: a punch fixing plate 201, a number punch 202, a scale punch 203, and a set screw 204. The number punch 202 and the scale punch 203 are both vertically mounted on the lower plane of the punch fixing plate 201 by the set screw 204, and are symmetrically arranged with the horizontal center line of the punch fixing plate 201 as the reference.

[0031] The 204 set screws not only improve the stability of the pressing process but also facilitate the maintenance and replacement of the punches. This symmetrical layout design allows a single upper die assembly to simultaneously press the symmetrically paired semi-circular excitation blocks required on both sides of the vibratory motor, significantly reducing the time required to replace the upper die assembly and improving pressing efficiency.

[0032] The lower template 5, the upper mold assembly 2, and the lower template 5 all have mold closing grooves 51 on their axes. The upper and lower mold closing grooves 51 are closed by the mold closing module 3.

[0033] The upper mold base 1 has longitudinally symmetrically distributed slots on its upper surface, which match the corresponding slots of the slider of the four-column hydraulic press (not shown in the figure) and are initially connected with bolts. The base 7 has longitudinally symmetrically distributed slots, which match the corresponding slots of the worktable of the four-column hydraulic press and are initially connected with bolts. The assembly module 3 is precisely placed into the pre-set assembly module positioning hole in the center of the lower template 5. The four-column hydraulic press is started, and the slider is controlled to slowly descend, driving the upper mold assembly 2 to align with the assembly module 3 placed on the lower template 5 until the mold is fully closed. After confirming that the mold closure and alignment are correct, the assembly module 3 is removed, and the connecting bolts between the upper mold base 1 and the hydraulic press slider, and between the base 7 and the hydraulic press worktable are finally tightened. The slider of the four-column hydraulic press is raised to a safe height. The semi-circular exciter block positioning mandrel 901 is fastened to the piston rod connection end of the three-axis cylinder 902 of the mandrel positioning mechanism 9 with bolts. The cylinder switch 903 is operated to raise the exciter block positioning mandrel 901 to the working position.

[0034] The lower mold base 6 is located at the bottom of the lower mold plate 5. The lower mold base 6 consists of four identical irregularly shaped pads, which are connected to the lower mold plate 5 and the base 7 by bolts. The lower mold base 6 has a cavity for accommodating the guide rail positioning mechanism 8 and a spindle positioning mechanism 9. The base 7 is installed at the bottom of the lower mold base 6.

[0035] A pair of clearance holes 52 are provided on the upper template 5 along the horizontal direction. A vibration block positioning and correction pin 4 is detachably installed in the clearance hole 52. The vibration block positioning and correction pin 4 is connected to the guide rail positioning mechanism 8 and is driven by the guide rail positioning mechanism 8 to achieve horizontal and longitudinal fine adjustment, so that the workpiece reaches the target position.

[0036] The guide rail positioning mechanism 8 includes a movable positioning push plate 801, a push plate pad 802, two linear slide rail sliders 803, two linear slide rail guides 804, a hand-cranked ball screw 805, a handwheel 806, a coupling 807, a support end 808, and a nut seat 809.

[0037] Two linear slide rails 804 and a hand-cranked ball screw 805 are arranged axially parallel. The linear slide rail slider 803 is slidably mounted on the linear slide rail 804. The movable positioning push plate 801 is threadedly connected to the hand-cranked ball screw 805 through the bottom nut seat 809. The movable positioning push plate 801 is provided with a slot for inserting the excitation block positioning correction pin 4.

[0038] By rotating the handwheel 806, the hand-cranked ball screw 805 is driven to rotate, thereby causing the excitation block positioning and correction pin 4 to move within the clearance hole 52, thus finely adjusting and positioning the workpiece.

[0039] Rotating the handwheel 806 drives the hand-cranked ball screw 805 to rotate via the coupling 807. The rotation of the screw causes the nut seat 809 and the movable positioning push plate 801 at the same height to move longitudinally along the linear slide rail 804, along with the push plate pad 802 and the linear slide rail slider 803. The movable positioning push plate 801 drives the excitation block positioning and correction pin 4 to move longitudinally, bringing it into contact with specific reference surfaces on both sides of the semi-circular excitation block, thereby achieving position correction of the excitation block.

[0040] The spindle positioning mechanism 9 positions the workpiece or facilitates the picking and placing of the workpiece by lifting and lowering it.

[0041] The spindle positioning mechanism 9 includes a vibratory block positioning spindle 901, a three-axis cylinder 902, a cylinder switch 903, and an air pipe 904. By replacing the vibratory block positioning spindle 901 with different specifications, vibratory blocks with different shaft holes can be pressed.

[0042] The cylinder body of the three-axis cylinder 902 passes through the mold closing groove 51 and the cylinder clearance hole on the moving positioning push plate 801 in sequence and is vertically installed at the center of the base 7.

[0043] The coaxiality tolerance of the piston rod axis of the three-axis cylinder 902, the center of the positioning hole of the lower template 5, and the center of the base 7 is controlled within ±0.10mm. The two guide rods built into the three-axis cylinder 902 can effectively eliminate the radial clearance of the piston rod and ensure the coaxial accuracy of the axial movement. By turning on the cylinder switch 903, the piston rod of the three-axis cylinder 902 is driven to rise, which drives the excitation block positioning spindle 901 at its top to rise, realizing the positioning of the workpiece; when the piston rod descends, it facilitates the picking and placing of the workpiece.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0045] In use, the shaft hole of the semi-circular exciter is fitted onto the raised exciter positioning mandrel 901, ensuring the workpiece is placed horizontally on the upper plane of the lower template 5. The exciter positioning correction pin 4 is inserted into the positioning pin hole on the moving positioning push plate 801 of the guide rail positioning mechanism 8. This correction pin passes through the pre-set clearance hole 52 on the horizontal center line of the lower template 5. The handwheel 806 of the guide rail positioning mechanism 8 is manually rotated to drive the moving positioning push plate 801 and its exciter positioning correction pin 4 to move longitudinally (parallel to the guide rail direction). Through the contact between the exciter positioning correction pin 4 and the specific reference surfaces on both sides of the semi-circular exciter, the workpiece is pushed to rotate around the semi-circular exciter positioning mandrel 901 until it reaches the preset adjustment angle position on the product drawing. The four-column hydraulic press is started, and the slider is controlled to slowly descend, driving the upper mold assembly 2 to smoothly press down until it fully contacts the upper plane of the semi-circular exciter and applies pressure, holding the pressure for 3 seconds. The slider is then controlled to slowly rise to a safe height. When cylinder switch 903 is turned off, the piston rod of three-axis cylinder 902 drives the semi-circular excitation block positioning spindle 901 to descend, so that its upper plane is lower than the upper plane of the lower template 5, and the pressed workpiece is removed.

[0046] In summary, this exciter block angle scale pressing and positioning fixture, through the setting of a guide rail positioning mechanism, can automatically and accurately align the exciter block with the upper mold assembly, thereby achieving fast and accurate scale pressing. The error range of the exciter block angle scale pressed by this device is within ±0.3°. At the same time, the liftable mandrel positioning mechanism facilitates the positioning and handling of workpieces.
