Description

Technical Field

[0001] The utility model relates to the technical field of processing jigs, and more specifically to a clamping head bending jig of a rotary switch housing. Background Art

[0002] As a common electrical control component, rotary switches are widely used in many fields. In the early stages of electronic equipment development, as the circuit system became increasingly complex, the demand for switches that are easy to operate and can achieve multi-function switching became increasingly prominent. Traditional toggle switches have a single function and are difficult to meet the diverse circuit connection and control needs, so rotary switches came into being.

[0003] Among the existing rotary switches, some rotary switches will install a shell made of metal material on the outside to protect the rotary switch. At present, the installation of the metal shell is mostly done manually with the help of corresponding jigs. The jig generally includes a pressing part and a stamping part. The pressing part is used to press the shell, and the stamping part is used to bend and fix the clamp of the shell. However, after the existing pressing part presses the shell, it is necessary to manually lock the pressing part using a locking pin, etc. After the stamping is completed, it is also necessary to manually unlock it, which is inconvenient in operation. In order to optimize the manual operation process, this application is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a clamping head bending fixture for a rotary switch housing, wherein the connecting rod mechanism has a self-locking state and does not require additional manual locking, making the operation more convenient.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping head bending jig for a rotary switch housing, comprising a machine base, a mounting seat for accommodating the rotary switch is arranged on the machine base, an upper pressure plate is arranged above the mounting seat, a lower punch is arranged below the mounting seat, a connecting rod mechanism and a stamping mechanism are arranged on the machine base, the connecting rod mechanism is used to drive the upper pressure plate to approach or move away from the mounting seat, the stamping mechanism is used to drive the lower punch to approach or move away from the mounting seat, and when the upper pressure plate approaches the mounting seat and abuts against the rotary switch housing, the connecting rod mechanism is in a self-locking state.

[0006] The utility model is further configured as follows: the machine base includes a square frame, a telescopic rod is arranged above the frame, the connecting rod mechanism is arranged in the frame, the connecting rod mechanism includes two groups of symmetrically arranged connecting rod groups, the connecting rod groups include connecting rods a, connecting rods b and connecting rods c, one end of the connecting rod a is hingedly arranged on the upper part of the frame, and the other end is hingedly arranged to the ends of the connecting rods b and connecting rods c, the other end of the connecting rod b is hingedly arranged on the telescopic rod, and the other end of the connecting rod c is hingedly arranged on the upper pressure plate.

[0007] The utility model is further configured as follows: a handle bar is hinged on the machine base, and the upper end of the telescopic rod is hingedly connected to the handle bar.

[0008] The utility model is further configured as follows: in the self-locking state, the connecting rod a and the connecting rod c are straightened in the vertical direction, and the connecting rod b is perpendicular to the straightening direction of the connecting rod a and the connecting rod c.

[0009] The utility model is further configured as follows: a limit block is arranged in the frame, and a magnetic attraction portion is arranged on the limit block. In the self-locking state, the magnetic attraction portion abuts against and is attracted to the side wall of the connecting rod a. When the upper pressure plate moves upward and away from the mounting seat, the magnetic attraction portion abuts against and is attracted to the upper side of the upper pressure plate.

[0010] The utility model is further configured as follows: the upper pressing plate comprises a through hole and a pressing rod, the through hole is for the rotating rod of the rotary switch to extend into, and the pressing rod is used to press down the clamping head on the rotary switch housing.

[0011] The utility model is further configured as follows: a through hole is arranged below the mounting seat corresponding to the position of the clamping head of the rotary switch housing, and the lower punch is inserted into the through hole to bend the clamping head.

[0012] The utility model is further configured as follows: the power source of the punching mechanism adopts an electric cylinder, a pneumatic cylinder or a hydraulic cylinder.

[0013] In summary, the utility model has the following beneficial effects:

[0014] Compared with the prior art, the utility model is provided with a connecting rod mechanism. After the upper pressing plate is pressed down into place, connecting rod a and connecting rod c are just in a vertically straightened state, and connecting rod b is just in a direction perpendicular to connecting rod a and connecting rod c. The entire connecting rod mechanism is in a self-locking state. At this time, when the lower punch is punching, the vertical upward force generated is just transmitted to the frame by connecting rod a and connecting rod c, and will not cause the movement of the connecting rod mechanism. When the upper pressing plate needs to be moved up, it is only necessary to move the telescopic rod upward, and the telescopic rod drives connecting rod b to move, and then drives connecting rod a and connecting rod c to move, so that the self-locking state can be released, and the upper pressing plate can rise smoothly. The setting of the connecting rod mechanism realizes self-locking and rapid self-locking release, and does not require additional manual operation, which is more convenient.

[0015] In addition, the utility model is also provided with a limit block, which has a magnetic attraction part. In the self-locking state and when the upper pressure plate rises to the highest position, the magnetic attraction part of the limit block can offset and attract each other, thereby maintaining the stability of the connecting rod mechanism and having high safety without being subjected to other external forces.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] This embodiment discloses a bending jig for a rotary switch housing. Figure 1-5 As shown, it includes a machine base 1, a mounting base 2 for accommodating a rotary switch is arranged on the machine base 1, an upper pressing plate 3 is arranged above the mounting base 2, a lower punch 4 is arranged below the mounting base 2, a connecting rod mechanism 5 and a punching mechanism 6 are arranged on the machine base 1, the connecting rod mechanism 5 is used to drive the upper pressing plate 3 to approach or move away from the mounting base 2, and the punching mechanism 6 is used to drive the lower punch 4 to approach or move away from the mounting base 2, and when the upper pressing plate 3 approaches the mounting base 2 and abuts against the rotary switch housing, the connecting rod mechanism 5 is in a self-locking state. Through the above structure, the locking of the upper pressing plate 3 is achieved by relying on the self-locking of the connecting rod mechanism 5, and no additional manual operation is required, which is more convenient to use.

[0024] Further, the base 1 includes a square frame 7, a telescopic rod 701 is arranged above the frame 7, and the connecting rod mechanism 5 is arranged in the frame 7. The connecting rod mechanism 5 includes two groups of symmetrically arranged connecting rod groups, including connecting rod a501, connecting rod b502 and connecting rod c503. One end of the connecting rod a501 is hinged to the upper part of the frame 7, and the other end is hinged to the ends of the connecting rods b502 and c503. The other end of the connecting rod b502 is hinged to the telescopic rod 701, and the other end of the connecting rod c is hinged to the upper pressure plate 3. Figure 3In simple terms, the connecting rod group is a connecting rod a, connecting rod b and connecting rod c, one end of which is hinged together, and the other end is hinged to the frame, telescopic rod and upper pressure plate respectively. In the self-locking state, connecting rod a501 and connecting rod c503 are stretched in the vertical direction, and connecting rod b502 is perpendicular to the stretching direction of connecting rod a and connecting rod c. Figure 2 When the horizontal T-shaped structure receives the upward force from the bottom, the force is directly applied to the frame along the connecting rod c and the connecting rod a, so that the connecting rod does not rotate and the connecting rod mechanism is kept stable. When the telescopic rod 701 moves upward, it drives the connecting rod b to deflect first, destroying the dead point position, so that the connecting rod assembly can be Figure 2 Folding is also performed to keep the upper pressing plate 3 away from the mounting base 2, so as to facilitate taking out and putting in the rotary switch.

[0025] Furthermore, a handle bar 8 is hingedly connected to the machine base 1, and the upper end of the telescopic rod 701 is hingedly connected to the handle bar 8. Manual operation is achieved through the handle bar 8.

[0026] Furthermore, a limit block 9 is provided in the frame 7, and a magnetic attraction portion 901 is provided on the limit block 9. In the self-locking state, the magnetic attraction portion 901 abuts against and attracts the side wall of the connecting rod a501. When the upper pressing plate 3 moves upward and away from the mounting seat 2, the magnetic attraction portion 901 abuts against and attracts the upper side of the upper pressing plate 3. The magnetic attraction portion 901 of the limit block 9 is a magnet, and the connecting rod and the upper pressing plate are made of magnetically attractable metal materials. With the setting of the limit block 9, after the upper pressing plate 3 rises or falls to the corresponding position, the limit block is used to limit and attract to maintain stability, thereby improving the overall safety and reliability.

[0027] Furthermore, the upper pressing plate 3 includes a through hole 301 and a pressing rod 302. The through hole 301 is for the rotating rod of the rotary switch to extend into, and the pressing rod 302 is used to press down the clamp on the rotary switch housing 10. Figure 4 The through hole 301 avoids the rotating rod of the rotary switch, and the pressing rod 302 is used to flatten the clamping head 11. Figure 4 As shown in the enlarged view in FIG. 1 , the function of the pressing rod 302 is to press the outwardly opened clamping head 11 shown by the dotted line in the figure inwardly to the position shown by the solid line, so as to facilitate the subsequent bending of the clamping head tail end by the lower punch 4.

[0028] Further, see Figure 5 The mounting seat 2 is provided with a through hole 201 below the position of the chuck of the rotary switch housing, and the lower punch 4 is inserted into the through hole 201 to bend the chuck. Specifically, the end of the lower punch 4 is provided with an arc groove, which is just adapted to the tail end of the chuck, and can be Figure 5 The tail end of the clamp shown by the dotted line is bent to form the tail end of the clamp shown by the solid line.

[0029] Furthermore, the power source of the stamping mechanism 6 can be any of the mature electric cylinders, air cylinders or hydraulic cylinders in the prior art, and those skilled in the art can flexibly adjust it according to actual needs.
