Description

Technical Field

[0001] The invention relates to the technical field of jigs and tools, and in particular to a jig and tool for positioning and clamping. Background Art

[0002] A fixture is a large category of tools used in carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement.

[0003] During use, the existing jigs and fixtures still use the traditional bolt fixing method, relying on the screwing pressure of the threaded structure to clamp the workpiece. However, the screwing of the screw to clamp the workpiece requires manual operation by the staff, and does not have the function of quickly clamping and positioning the workpiece. For this reason, we propose a jig and fixture for positioning and clamping to solve the existing problems. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the above technical problems, the present invention provides a tooling and fixture for positioning and clamping.

[0006] (II) Technical solution

[0007] A tooling jig for positioning and clamping comprises a support plate, a stroke plate, a first hydraulic rod, a screw rod and a second hydraulic rod. The upper end of the support plate is provided with a symmetrically distributed limit seat, the limit seat is provided with a first hydraulic rod inside, the outer wall of the first hydraulic rod is sleeved with a stroke plate, the opposite end of the first hydraulic rod is provided with a clamping plate, the second hydraulic rod is provided inside the support plate, the support plate is provided with a screw hole, and a screw rod is rotatably inserted in the screw hole.

[0008] When using a positioning and clamping tool in the present solution, the second hydraulic rod operates to drive the magnetic plate to adjust the height, the metal workpiece is placed on the upper end of the magnetic plate, and the rotating handle drives the screw to rotate inside the screw hole to push the stroke plate. While adjusting the height of the first hydraulic rod, the longitudinal position of the clamping plate is adjusted. The operation of the first hydraulic rod drives the clamping plate to move relative to the clamping plate, and the clamping plate clamps the workpiece. The limit plate moves to the bottom of the workpiece, so that the workpiece can be quickly positioned and clamped, and the magnetic plate moves downward under the operation of the second hydraulic rod to ensure the processing of the workpiece.

[0009] Preferably, the travel plate is slidably mounted inside the limit seat. The travel plate is limited inside the limit seat and can only slide longitudinally, thereby avoiding the problem of instability of the travel plate when it is lifted.

[0010] Preferably, the clamping plate is provided with a limit plate at one opposite end, and the limit plate supports the bottom of the clamped workpiece to maintain the stability of the bottom of the clamped workpiece.

[0011] Preferably, a magnetic plate is disposed at the upper end of the second hydraulic rod, and the magnetic plate performs preliminary magnetic adsorption on the bottom of the workpiece.

[0012] Preferably, a rotation handle is provided at the lower end of the screw rod. When the screw rod is rotated, the screw rod can be rotated by grasping the rotation handle, so that the rotation of the screw rod is more labor-saving.

[0013] Preferably, a bearing is embedded in the lower end of the stroke plate, and the upper end of the screw is rotatably inserted into the bearing. When the lateral rotational force of the screw acts on the stroke plate, the upper end of the screw rotates inside the bearing, so that when the screw rotates, only a longitudinal driving force is applied to the stroke plate, thereby ensuring effective longitudinal movement of the stroke plate.

[0014] (III) Beneficial effects

[0015] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0016] The present invention supports the bottom of the metal workpiece through a magnetic plate, which plays a role in preliminary adsorption and positioning. When the first hydraulic rod is in operation, the clamping plate is mobilized to clamp the outer wall of the workpiece to keep the workpiece stable. The clamping plate is operated by pushing the hydraulic rod, so that the workpiece can be quickly positioned and clamped; the rotating screw drives the stroke plate to move longitudinally, and the operation of the second hydraulic rod drives the magnetic plate to move longitudinally, which can effectively clamp the workpiece with adjusted specifications, maintain the pre-support of the bottom of the workpiece, and the bottom support of the workpiece by the limit block after clamping.

[0021] The present invention provides a tooling tool for positioning and clamping. In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. Specific embodiments

[0023] Embodiment 1

[0024] like Figure 1-3 As shown, a positioning and clamping tool proposed by the present invention includes a support plate 1, a stroke plate 2, a first hydraulic rod 3, a screw 8 and a second hydraulic rod 9. A symmetrically distributed limit seat 7 is arranged on the upper end of the support plate 1, and the first hydraulic rod 3 is arranged inside the limit seat 7. The outer wall of the first hydraulic rod 3 is sleeved with the stroke plate 2, and the stroke plate 2 is slidably installed inside the limit seat 7. A clamping plate 4 is arranged at the opposite end of the first hydraulic rod 3, and a limit plate 6 is arranged at the opposite end of the clamping plate 4. A second hydraulic rod 9 is arranged inside the support plate 1, and a magnetic plate 5 is arranged on the upper end of the second hydraulic rod 9.

[0025] The working principle based on Example 1 is: the metal workpiece is placed on the upper end of the magnetic plate 5, the second hydraulic rod 9 operates to drive the magnetic plate 5 to adjust the height, and the bottom support of the workpiece with changed height is responded to. The first hydraulic rod 3 operates to drive the clamping plate 4 to move relatively, and the clamping plate 4 clamps the workpiece, so that the workpiece can be quickly positioned and clamped.
