Abstract

The utility model provides a clamp capable of sensing in place, which comprises a controller and clamp arms, wherein the controller controls the clamp arms to open and stop opening, the clamp comprises a sensor for sensing the opening of the clamp arms in place, the sensor is connected with the controller and comprises a sensed part moving along with the opening of the clamp arms, and the sensor senses the opening of the clamp arms in place by sensing the sensed part; the sensed part can be connected to different positions on the clamping arm, and the sensor senses different opening degrees of the clamping arm when sensing the sensed part. If a wider workpiece needs to be clamped, the sensed part needs to move for a longer distance along with the clamping arm to be sensed only if the sensed part is arranged at a position, which is farther away from the sensor, of the clamping arm, which means that the opening amplitude of the clamping arm is increased to adapt to the wider workpiece, and conversely, the sensed part is arranged at a position, which is closer to the sensor, of the clamping arm, which means that the opening amplitude of the clamping arm is decreased to adapt to the narrower workpiece, so that the clamp can adapt to workpieces with various width specifications.

Background

At present, the applicant has developed an in-place sensing clamp, which includes a first clamping arm and a second clamping arm, a straight rail, a motor and a controller, wherein the two clamping arms are movably mounted on the straight rail, and the motor drives the two clamping arms to move in a manner of approaching to and departing from each other along the straight rail. The clamp is provided with an inductor communicated with the controller, and an induction area of the inductor is positioned on an open moving path of the first clamping arm; the two clamping arms clamp the workpiece together, when the first clamping arm moves to a sensing area of the sensor, the sensor transmits a position signal to the controller, the controller which receives the position signal controls the motor to stop, and the two clamping arms are opened to the position at the moment, which means that the previous workpiece is loosened and the next workpiece can be clamped. Generally speaking, the clamp is used for continuously clamping workpieces with the same width specification, if the clamp needs to be changed to clamp workpieces with other width specifications, an operator is required to detach the inductor and install the inductor at other positions, so that the moving distance from the first clamping arm to the sensing area is changed, and the two clamping arms are opened in place when the first clamping arm moves to the sensing area.

The prior art has the defects that: the inductor is the precision part, need debug again after the inductor position changes and calibrate just can use, need expend a lot of time when leading to anchor clamps to press from both sides the work piece of another batch of other width specifications and debug the calibration, has reduced the operating efficiency when pressing from both sides the work piece of getting other width specifications.

Detailed Description

As shown in fig. 1, the jig includes a cylindrical jig body 7, the jig body 7 is provided with a gear 3 coaxially at a center of a circle on an upper end surface, and the gear 3 is provided with a motor (hidden in the drawing). Two parallel tracks are respectively arranged on two sides of the gear 3, wherein the first track 6 is provided with a first clamping arm 1, the second track 11 is provided with a second clamping arm 8, the bottom of each clamping arm is provided with a rack 2 meshed with the gear 3, and the motor-driven gear 3 rotates to drive the rack 2 to move, so that the two clamping arms move along the tracks in a mutually approaching mode and a mutually departing mode. The clamp is provided with a controller (not shown in the figure) and a contact sensor 5 for sensing the opening position of the clamping arms is arranged beside the first track 6, the first clamping arm 1 is provided with a sensed part 4 for contacting the contact sensor 5 for the self rack 2 (the first clamping arm 1 is provided with one sensed part 4 more than the second clamping arm 8, and the rest structures are the same). As shown in fig. 2, two second screw holes are provided at one position of the first clamping arm 1 (the two second screw holes are shielded by two screws 10), two through holes are provided on the sensed part 4 (the two through holes are also shielded by the two screws 10), and the two screws 10 respectively pass through the two through holes and then are respectively connected to the two second screw holes.

It should be noted that the gear 3 provided with the motor functions as a driving device in the present embodiment.

The two clamping arms clamp a workpiece together, when the workpiece needs to be loosened, the motor drives the gear 3 to enable the two clamping arms to be away from each other and open, when the sensed part 4 moves along with the opening of the first clamping arm 1 and contacts the contact sensor 5, the contact sensor 5 sensing the sensed part 4 transmits an in-place signal to the controller, the controller receiving the in-place signal stops controlling the two clamping arms to stop moving simultaneously by controlling the motor, and at the moment, the two clamping arms are already opened in place, which means that the workpiece is loosened and can clamp the next workpiece. If the next workpiece to be clamped is narrower than the previous workpiece, as shown in fig. 2, the other position of the first clamping arm 8 is provided with two first screw holes 9, the operator can detach the sensed part 4 from the second screw hole and connect the sensed part to the first screw holes 9, and the sensed part 4 can be sensed by the contact sensor 5 after moving a shorter distance along with the first clamping arm 1, so that the two clamping arms can be opened in place more quickly. Therefore, when the sensed part 4 is connected to different positions on the clamping arm, the contact sensor 5 senses different opening degrees of the clamping arm when sensing the sensed part 4.

It is not preferable that the touch sensor 5 is changed to another sensor (e.g., a photoelectric sensor) to sense the sensed part 4, so as to sense that the first clamping arm 8 is opened.

Unpreferably, the sensed part 4 screwed on the first clamping arm 8 is changed into a sliding block, a screw hole is not formed in the first clamping arm 1, a sliding groove is formed in the first clamping arm 1, the sliding block is movably mounted on the sliding groove, the sliding block can move transversely, and the sensed part 4 can be connected to different positions on the first clamping arm 8. The slide block as the sensed part 4 can move to different positions of the first clamping arm 8, and the sensor senses different opening degrees of the first clamping arm 8 when the sensed part 4 is sensed.
