Description

Technical Field

[0001] This utility model relates to the field of potentiometer technology, and in particular to a highly applicable potentiometer pin shaping fixture. Background Technology

[0002] A potentiometer is a resistive element with three leads whose resistance can be adjusted according to a certain rule. A potentiometer is usually composed of a resistive element and a movable brush. When the brush moves along the resistive element, a resistance value or voltage that is related to the displacement is obtained at the output terminal. A potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor. Since its function in the circuit is to obtain an output voltage that is related to the input voltage, it is called a potentiometer.

[0003] like Figures 2-3 The potentiometer shown includes a potentiometer housing 501. Pin 0 502, pin 1 503, and pin 2 504 are sequentially arranged on the periphery of the housing 501. A positioning boss 505 is provided at the bottom of the housing 501. For this potentiometer, a potentiometer pin shaping fixture is needed to adjust the distance between pin 1 503 and pin 2 504, and to shape the individual pins 1 503 and 2 504.

[0004] Traditional potentiometer lead shaping fixtures have shortcomings in use. Due to the deformation of the potentiometer leads, feeding and unloading the potentiometers into the fixture often becomes difficult, significantly impacting shaping efficiency. Therefore, it is necessary to optimize and improve the traditional potentiometer lead shaping fixture. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a highly applicable potentiometer pin shaping fixture.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A highly adaptable potentiometer pin shaping fixture includes a mounting frame, a lower mold assembly, a vertical push rod, and an upper mold assembly. The lower mold assembly is mounted on the bottom plate of the mounting frame, and the upper mold assembly, which can be raised and lowered, is mounted on the top plate of the mounting frame via the vertical push rod.

[0008] The potentiometer includes a potentiometer housing, with pins 0, 1, and 2 arranged sequentially on the periphery of the housing, and a positioning boss at the bottom of the housing.

[0009] The lower mold assembly includes a lower mold base. The upper side of the lower mold base has a transverse groove, a longitudinal groove, and a positioning groove located between the two. A locking block is installed in the longitudinal groove. Baffles are installed at both ends of the lower mold base in the transverse groove by fasteners. A transverse spring is installed on the inner side of the baffle. Two movable seats are slidably installed in the transverse groove. The side end of the movable seat has a spring groove for installing the transverse spring. The upper outer end of the movable seat has a lower wedge block. The upper inner end of the movable seat has an inner support block. The upper side of the movable seat near the inner support block has a support groove for supporting pin 1 or pin 2.

[0010] The upper mold assembly includes an upper mold base, two guide blocks are symmetrically installed on the lower rear part of the upper mold base, two upper wedge blocks are symmetrically installed on the lower front part of the upper mold base, and a protrusion is provided on the lower middle part of the upper mold base. A pressure sensor and two vertical shaping pressure plates are installed on the protrusion.

[0011] Furthermore, the width of the positioning groove in the lower mold assembly matches the width of the positioning boss.

[0012] Furthermore, the bottom end of the card block is restricted to the bottom of the longitudinal groove, and a longitudinal spring is installed between the outer end of the card block and the longitudinal groove.

[0013] Furthermore, the spacing between the two guide blocks is coordinated with the thickness of the locking block, so that when the two guide blocks move down with the lower mold assembly, the locking block can engage with the area between the two guide blocks.

[0014] Furthermore, a sloping sliding fit is formed between the lower wedge and the upper wedge. When the upper wedge moves down until its sloping surface contacts the mating sloping surface of the lower wedge, the upper wedge continues to move down, which can drive the upper wedge and the movable seat it is located to move outward.

[0015] Furthermore, the spacing between the two vertical shaping plates is the standard spacing between pin 1 and pin 2.

[0016] Furthermore, the bottom end of the vertical shaping plate is provided with a shaping protrusion structure, the width of the support groove is 1.5 to 2 times the width of pin 1 or pin 2, the support groove is provided with a shaping concave surface structure that matches the shape of the shaping protrusion structure near the inner end, and the initial horizontal spacing between the support grooves on the two movable seats is 0.6 to 0.8 times the standard spacing.

[0017] Furthermore, it also includes a controller. The pressure sensor has an arc surface that matches the shape of the potentiometer housing. When the pressure sensor detects that the pressure has reached the set value, it sends a signal to the controller, which controls the vertical push rod to stop moving. At this time, the shaping protrusion of the vertical shaping plate just abuts against the shaping concave surface of the support groove, and the horizontal distance between the support grooves on the two movable seats is just equal to the standard distance between pin 1 and pin 2.

[0018] The beneficial effects of this utility model are:

[0019] This utility model has a reasonable tooling design, mainly consisting of a mounting frame, a lower mold assembly, a vertical push rod, and an upper mold assembly. The lower mold assembly has two movable seats that can be adjusted in position. The initial horizontal distance between the support grooves on the two movable seats can be set to be small, making the feeding of the potentiometer product smoother. The upper wedge block in the upper mold assembly drives the movable seats with the lower wedge block to move outward, so that the horizontal distance between the support grooves on the two movable seats gradually increases to the standard distance, thereby meeting the distance shaping requirements between pins 1 and 2 in the potentiometer. The vertical shaping pressure plate in the upper mold assembly and the support grooves on the movable seats are used to shape the shape of pins 1 and 2 respectively.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0037] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figure 1 As shown, this embodiment provides a highly applicable potentiometer pin shaping fixture, including a mounting frame 1, a lower mold assembly 2, a vertical push rod 3, and an upper mold assembly 4. The lower mold assembly 2 is mounted on the bottom plate of the mounting frame 1, and the upper mold assembly 4, which can be raised and lowered, is mounted on the top plate of the mounting frame 1 via the vertical push rod 3.

[0039] like Figures 2-3As shown, potentiometer 5 includes potentiometer housing 501. Pin 0 502, pin 1 503 and pin 2 504 are arranged sequentially on the periphery of potentiometer housing 501. A positioning boss 505 is provided at the bottom of potentiometer housing 501.

[0040] like Figures 4-6 As shown, the lower mold assembly 2 includes a lower mold base 201. The upper side of the lower mold base 201 has a transverse groove 202, a longitudinal groove 203, and a positioning groove 209 located between them. A locking block 204 is installed in the longitudinal groove 203. Baffles 205 are installed at both ends of the lower mold base 201 via fasteners 206. A transverse spring 208 is installed inside the baffle 205. Two movable seats 207 are slidably installed in the transverse groove 202. The movable seats 207 have spring grooves 207a on their sides for easy installation of the transverse springs 208. A lower wedge block 207b is provided at the upper outer end of the movable seat 207, and an inner support block 207c is provided at the upper inner end of the movable seat 207. A support groove 207d is provided on the upper side of the movable seat 207 near the inner support block 207c to support pin 1 503 or pin 2 504.

[0041] like Figures 7-9 As shown, the upper mold assembly 4 includes an upper mold base 401. Two guide blocks 402 are symmetrically mounted on the lower rear part of the upper mold base 401, and two upper wedge blocks 403 are symmetrically mounted on the lower front part of the upper mold base 401. A protrusion 404 is provided in the lower middle part of the upper mold base 401, and a pressure sensor 405 and two vertical shaping pressure plates 406 are mounted on the protrusion 404.

[0042] In this embodiment, the width of the positioning groove 209 in the lower mold assembly 2 matches the width of the positioning boss 505.

[0043] In this embodiment, the bottom end of the locking block 204 is restricted to the bottom of the longitudinal groove 203, and a longitudinal spring is installed between the outer end of the locking block 204 and the longitudinal groove 203.

[0044] In this embodiment, the bottom ends of the sliding seat 207 and the locking block 204 are each configured as an inverted T-shaped anti-detachment structure that is narrower at the top and wider at the bottom.

[0045] In this embodiment, the gap between the two guide blocks 402 is matched with the thickness of the locking block 204. When the two guide blocks 402 move down with the lower mold assembly 4, the locking block 204 can be locked into the area between the two guide blocks 402.

[0046] In this embodiment, a sloped sliding fit is formed between the lower wedge block 207b and the upper wedge block 403. When the upper wedge block 403 moves down until its slope contacts the mating slope of the lower wedge block 207b, the continued downward movement of the upper wedge block 403 can drive the upper wedge block 207b and its corresponding movable seat 207 to move outward. In this way, the two inner support blocks 207c are moved away from each other.

[0047] In this embodiment, the spacing between the two vertical shaping plates 406 is the standard spacing between pin 1 503 and pin 2 504.

[0048] In this embodiment, the bottom end of the vertical shaping plate 406 is provided with a shaping protrusion structure, the width of the support groove 207d is 1.5 to 2 times the width of pin 1 503 or pin 2 504, the support groove 207d is provided with a shaping concave surface structure that matches the shape of the shaping protrusion structure near the inner end, and the initial horizontal spacing of the support groove 207d on the two movable seats 207 is 0.6 to 0.8 times the standard spacing.

[0049] In this embodiment, a controller is also included. The pressure sensing side of the pressure sensor 405 is provided with an arc surface that matches the shape of the potentiometer housing 501. When the pressure sensor 405 detects that the pressure has reached the set value, it sends a signal to the controller, and the controller controls the vertical push rod 3 to stop moving. At this time, the shaping protrusion structure of the vertical shaping plate 406 just abuts against the shaping concave structure of the support groove 207d. The horizontal spacing of the support groove 207d on the two movable seats 207 is just equal to the standard spacing of pin 1 503 and pin 2 504.

[0050] A specific application of this embodiment is as follows: This tooling mainly consists of a mounting frame 1, a lower mold assembly 2, a vertical push rod 3, and an upper mold assembly 4. The lower mold assembly 2 is provided with two movable seats 207 that can be adjusted in position. The initial horizontal distance between the support grooves 207d on the two movable seats 207 can be set to be small, so that the potentiometer product is fed out more smoothly. The upper wedge block 403 in the upper mold assembly 4 drives the movable seats 207 with the lower wedge block 207b to move outward, so that the horizontal distance between the support grooves 207d on the two movable seats 207 gradually increases to the standard distance, thereby meeting the distance shaping requirements between pin 1 503 and pin 2 504 in the potentiometer 5. The vertical shaping pressure plate 406 in the upper mold assembly 4 and the support grooves 207d on the movable seats 207 are used to shape the shape of pin 1 503 and pin 2 504 respectively.
