Description

Technical Field

[0001] The utility model relates to the technical field of boot processing, in particular to a positioning fixture for processing men's leisure boots. Background Art

[0002] The main difference between boots and shoes lies in their use, design and appearance. Compared with shoes, boots are usually designed to be more sturdy and durable, suitable for wearing in bad weather and complex terrain, and more suitable for male users with more activities. Casual boots can be both sturdy and durable, with good comfort and good appearance, so they are more popular with male users.

[0003] When processing men's casual boots in the prior art, some clamps can only play the role of clamping and fixing, but lack the function of positioning the boot body. It is necessary to manually place the boot body exactly on the lower side of the processing device so that the processing equipment can effectively process the casual boots. This increases the workload of the workers and results in low processing efficiency of the casual boots. For this reason, we propose a positioning clamp for processing men's casual boots.

The lateral clamping unit can clamp the casual boot from both sides, and cooperate with the sole positioning unit to achieve multi-directional positioning of the casual boot, so that the casual boot can be placed in the middle of the placement table.

[0010] Furthermore, the sole positioning unit also includes distance sensor 2, hydraulic cylinder 1, linkage rod and hydraulic cylinder 2. A longitudinal distance sensor 2 is installed at both front and rear ends of the slide seat. The outer ends of the two connecting push rods are fixedly connected to a vertical linkage rod.

A vertical hydraulic cylinder 2 is installed in the center of the installation groove. The telescopic end of hydraulic cylinder 2 faces upward and is fixedly connected to the inside of the sole block. Hydraulic cylinder 2 is used to provide power for the sole block to slide up and down. When the sole block is clamped upward into the groove at the bottom of the casual boots, the distance sensors 2 on the front and rear sides of the slide start to work. The two distance sensors 2 detect the distance between them and the groove wall. The PLC controller compares and analyzes the distance values ​​on the front and rear sides, and then controls the hydraulic cylinder 1 on the corresponding side to work. Hydraulic cylinder 1 drives the slide to the middle position of the slide groove through the linkage rod and the connecting push rod. The casual boots move with the slide under the action of the sole block, thereby realizing the longitudinal positioning of the casual boots to be processed.

[0011] Furthermore, the sole positioning unit also includes an auxiliary telescopic rod and a PLC controller. Two auxiliary telescopic rods are fixedly connected between the sole block and the bottom. The two auxiliary telescopic rods are symmetrically distributed on the left and right sides of the hydraulic cylinder 2. The PLC controller is installed on the front right side of the placement table. The distance sensor 1, the distance sensor 2, the hydraulic cylinder 1 and the hydraulic cylinder 2 are all bidirectionally electrically connected to the PLC controller. The auxiliary telescopic rod is used to bear the horizontal friction force brought by the hydraulic cylinder 2 on behalf of the sole of the boot, and to enable the sole block to be lifted and lowered smoothly. Before the processed boot body is placed, the sole block is stored in the installation groove, and the upper end is flush with the end surface of the slide seat.

[0012] Furthermore, the lateral clamping unit comprises a sliding rod, a spring and a top block. The middle part of the upper end of the left and right side walls of the placing platform is slidably connected to a transverse sliding rod. The section of the sliding rod extending to the middle groove is sleeved with a spring, and a top block is fixedly connected to the inward end of the two sliding rods, and one end of the spring is pressed against the end surface of the top block.

The longitudinal rod bodies are flush with the upper end of the slide and are slidably connected with the front and rear walls of the placement table. Four arc-shaped limit blocks are fixedly connected to the position near the middle of the groove at the upper end of the placement table. The four arc-shaped limit blocks are diagonally distributed in a rectangular shape and are arranged in an embracing posture. The arc-shaped limit block is used to initially limit the leisure boots, so that during the longitudinal positioning process, the leisure boot frame can be placed inside, so that the leisure boots can produce relative displacement with the slide, which is convenient for the positioning device to find the groove part of the boot sole. The stop rod can move with the slide and cover the gap area between the slide and the slide groove.

When the tool moves in a runway-shaped trajectory, the four sides of the leisure boots are processed, the slide seat 33 can slide longitudinally along the slide groove 31, and the connecting push rod 32 is driven by the power devices on the front and rear sides of the device to further drive the slide seat 33 to slide. The mounting groove 35 is used for the installation of the sole block 34. When the slide seat 33 is longitudinally displaced relative to the sole of the boot, the distance sensor 36 monitors the distance between the sole block 34 and the sole of the boot. When the monitored distance value becomes larger, it indicates that the sole block 34 is vertically corresponding to the groove at the bottom of the leisure boot. At the same time, the sole Under the action of the lower power device, the block 34 is clamped upward in the groove at the bottom of the leisure boot, which has the effect of limiting the leisure boot and facilitating the subsequent positioning operation of the leisure boot; the hydraulic cylinder 310 is used to provide the power for the sole block 34 to move up and down. When the sole block 34 is clamped upward to the groove at the bottom of the leisure boot, the distance sensors 37 on the front and rear sides of the slide seat 33 start to work. The two distance sensors 37 detect the distance between them and the groove wall, and the PLC controller 312 compares and analyzes the distance values ​​on the front and rear sides, thereby controlling the corresponding side. When the hydraulic cylinder 1 38 is working, the hydraulic cylinder 1 38 drives the slide 33 to move to the middle position of the slide groove 31 through the linkage rod 39 and the connecting push rod 32.
