Problems solved by technology

[0002] At present, in many workpiece-intensive assembly occasions, it is often necessary to pick, place, load or unload parts at different intervals. The action requires accuracy, speed and high reliability. Multi-power devices are often used to realize the opening and closing and clamping actions respectively, and more The realization of pneumatic devices not only consumes high energy, but also has average efficiency, consistent action and low reliability, and the air circuit components are prone to aging, which is subject to high environmental requirements.

Embodiment 1

[0033] Such as figure 1 As shown, the variable pitch pick-and-place device includes a frame 1, on which a camshaft 2 driven by a power unit is rotatably installed, and two jaw seat installation shafts parallel to the camshaft 2 are provided on both sides of the camshaft 2 3. Two gripper seats 4 are installed on each gripper seat installation shaft 3, and the gripper seats 4 on the two gripper seat installation shafts 3 are arranged in pairs, and the paired two gripper seats 4 form a clip claw set, such as Figure 5 As shown, a jaw monomer 5 is installed on each jaw base 4, and two jaw monomers 5 on each jaw base group form a pair of jaws, and a camshaft 2 is fixedly installed for each The plate cam 6 that opens and closes between the two jaw seats 4 of each jaw seat group and the end face cam 7 that is used to make the axial split distance between each jaw seat group and group along the camshaft, The structure of the plate cam 6 is as Figure 6a and Figure 6b As shown, th...

Embodiment 2

[0041] Such as figure 2 As shown, a pick-and-place device with variable pitch, its structure is basically the same as that of Embodiment 1, the difference is that the jaw seat group includes a fixed jaw seat group and several movable jaw seat groups, and several movable jaw seat groups The seat group is arranged on the same side of the fixed jaw seat group, and the fixed jaw seat group is limited along the axial direction of the camshaft 2. The fixed jaw seat 41 is provided with a limit groove 14, and the plate cam 6 is restrained and installed in the limit groove 14 Inside, an end face cam is arranged between the two movable jaw seats 42 of each movable jaw seat group, and a flange that abuts against the end face cam is provided on the two movable jaw seats 42 of each movable jaw seat group. , in this embodiment, the fixed jaw seat 41 only opens and closes without displacement in the axial direction. The direction of the clamping jaw seat 41 is fixed, and the lead of the en...

Embodiment 3

[0043] Such as image 3 , Figure 4 and Figure 5 Commonly shown, a variable pitch pick-and-place device, its structure is basically the same as that of Embodiment 2, the difference is that, as a preferred structure to replace the sliding sleeve, the two jaw seat installation shafts 3 are respectively installed on a sliding seat 16, at this time, the first reset mechanism is arranged between the two sliding seats 16, and each sliding seat 16 is provided with a jaw seat installation chamber, the jaw seat installation shaft 3 passes through the jaw seat installation cavity, and the fixed clip The jaw base 41 and several movable jaw bases 42 are installed in the jaw base installation cavity. Based on the above structure, the first reset mechanism includes a spring limit post 11 installed on the frame 1, and two sliding bases 16 are slidably installed on the spring On the limit post 11 , a second compression spring 17 is provided between each sliding seat 16 and the spring limit...

Abstract

The invention discloses a variable-spacing picking and placing device. A camshaft is rotatably installed on a frame. Two clamping jaw seat installation shafts which are in parallel with the camshaft are arranged on the two sides of the camshaft. Camping jaw seats are installed on each clamping jaw seat installation shaft. The clamping jaw seats on the two clamping jaw seat installation shafts are arranged in a paired way. The two paired clamping jaw seats form a clamping jaw seat group. A plate cam which is used for enabling the two clamping jaw seats to be opened and closed and an end surface cam which is used for enabling the clamping jaw seat groups to increase or decrease the spacing along the axial direction of the camshaft are fixedly installed on the camshaft. A first restoring mechanism is arranged between the two clamping jaw seat installation shafts. The variable-spacing picking and placing device additionally comprises a second restoring mechanism which is matched with the end surface cam to realize the decrease of the spacing between the clamping jaw seat groups. The variable-spacing picking and placing device has the advantages that the spacing-increasing clamping action can be conveniently controlled by controlling the rotating speed of a motor, different picking and placing process requirements are realized, the production efficiency is improved, the structure is greatly simplified, the cost is low and the occupied space is small.

Description

technical field [0001] The invention relates to a material clamping device, in particular to a variable-pitch pick-and-place device. Background technique [0002] At present, in many workpiece-intensive assembly occasions, it is often necessary to pick, place, load or unload parts at different intervals. The action requires accuracy, speed and high reliability. Multi-power devices are often used to realize the opening and closing and clamping actions respectively, and more The realization of pneumatic devices not only consumes high energy, but also has average efficiency, consistent action and low reliability, and the air circuit components are prone to aging, which is subject to high environmental requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a variable-pitch pick-and-place device, which can conveniently control the pick-and-place action by controlling the motor speed, realize different pick-and-...
