Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a clamp group for producing and processing a combination lock cylinder. Background Art

[0002] After the initial production of the lock core of a mechanical combination lock is completed, process steps such as milling grooves and drilling are required on the surface and inside. During the process, the lock core workpiece needs to be placed on a fixture table and clamped. Most of the existing fixtures are manually clamped. Due to the small size of the lock core workpiece and batch production, manual clamping and disassembly reduce production efficiency. In addition, since the material of the lock core is relatively soft, ordinary fixtures can easily damage the surface of the lock core during clamping, which urgently needs to be improved.

The clamping block for clamping the workpiece is detachably set in the installation groove. The workpiece can be clamped by selecting a clamping block that is suitable for the workpiece and will not clamp the workpiece according to the shape and size of the workpiece itself, which ensures fast clamping while also ensuring that the workpiece will not be clamped.

[0005] The present invention is further configured such that end surfaces of the pair of clamp blocks are each provided with a clamping groove that matches the shape of the outer peripheral surface of the lock core.

[0006] With the above technical solution, since the end faces of the pair of clamp blocks are provided with clamping grooves matching the outer peripheral shape of the lock core, the outer peripheral shape of the workpiece can be further fitted during clamping, thereby enhancing the protection of the workpiece.

[0007] Further configuration of the utility model: the mounting plate is also provided with a discharging device for automatically discharging the processed lock core, the discharging device includes a blanking drive cylinder, a pushing drive cylinder, a bottom support plate and a pushing plate, the blanking drive cylinder and the pushing drive cylinder are both fixedly connected to the mounting plate, the bottom support plate is connected to the piston rod of the blanking drive cylinder, the pushing plate is connected to the piston rod of the pushing drive cylinder, the movable clamping block and the fixed clamping block are both provided with a discharging groove at a position below the clamping block, the pushing plate is arranged in the discharging groove, the movable clamping block is provided with a through groove matching the bottom support plate, and the bottom support plate is arranged in the through groove.

[0008] The push plate is controlled by the push drive cylinder to automatically push out the processed lock core for subsequent collection.

[0009] The utility model is further configured as follows: anti-collision cushions are provided on the end surface of the mounting plate located in the discharge chute and the end surface of the push plate.

[0010] By adopting the above technical solution, since anti-collision pads are provided on the end surface of the mounting plate in the discharge chute and the end surface of the push plate, the workpiece can be further protected when it falls and is pushed out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] like Figure 1-2 As shown, a fixture group for the production and processing of a password lock cylinder includes a mounting plate 1, a mounting clamp and a pair of clamp blocks 2, the clamp block is arranged on the mounting clamp, the mounting clamp is arranged on the mounting plate, the mounting clamp includes a movable clamp 3 and a fixed clamp 4, the fixed clamp is fixedly connected to the mounting plate, and a driving mechanism is also provided on the mounting clamp, the driving mechanism includes a driving cylinder 5, a pair of slide rods 6 and a connecting plate 7, the driving cylinder is fixedly arranged on the fixed clamp, the pair of slide rods are fixedly arranged on the movable clamp, the fixed clamp is provided with a pair of through holes 8 matching the slide rods, the pair of slide rods are respectively arranged in a pair of through holes, one end of the pair of slide rods is connected to the connecting plate, the piston rod of the driving cylinder is connected to the connecting plate, the movable clamp and the fixed clamp are both provided with mounting grooves 9 matching the clamp block, and the pair of clamp blocks are detachably arranged in the mounting grooves.

[0015] The tightness of the movable clamping block is controlled by driving an air cylinder, a pair of sliding rods and a connecting plate. Mounting slots are then opened on the movable clamping block and the fixed clamping block. The clamping block for clamping the workpiece is detachably set in the mounting slot. The workpiece can be clamped by selecting a clamping block that is suitable for the workpiece and will not be clamped according to the shape and size of the workpiece itself. This ensures fast clamping while also ensuring that the workpiece will not be clamped.
