Description

Technical Field

[0001] This utility model relates to a gauge clamping device, and more particularly to a gauge clamping device with bidirectional adjustable pressure. Background Technology

[0002] like Figure 1 As shown, most of the existing inspection clamping mechanisms currently use quick clamp standard parts for clamping. This type of clamping mechanism has a single clamping direction and is only suitable for unidirectional clamping of some plastic and sheet metal parts because it is only equipped with one pressure head. For packaging parts that need to be inspected for double-layer thickness at the same time, since the two layers of materials require different pressure heads, the entire clamping mechanism needs to be replaced, which is inconvenient to use.

[0007] The rotating block has threaded holes on two opposite sides. The supporting rotating shaft passes through the rotating block and has at least one protrusion. The rotating block has a first cavity that mates with the protrusion. During the rotation of the supporting rotating shaft, the force applied by the protrusion to the first cavity forms a torque that drives the rotating block to rotate.

A cylindrical second cavity is provided inside the rotating block. The buffer spring is located inside the second cavity, sleeved on the support shaft, with one end supported on the baffle and the other end supported on the inner wall of the second cavity.

[0010] The clamping mechanism also includes two limiting nuts, which are respectively fitted onto the first pressure head and the second pressure head to fix the depth of the first pressure head and the second pressure head inserted into the threaded hole.

[0016] The connecting part is connected to the first connecting rod through a fixing screw.

[0017] A sheath is arranged on the hand holding part.

[0018] The driving mechanism is detachably connected to the support mechanism.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1.

[0021] 2. The insertion depth of the first pressing head and the second pressing head is fixed by the limiting nut, so that the extension length of the pressing head is fixed, and the stability is improved.

[0022] 3. By arranging the spring, the overall structure can be prevented from being loosened due to the lateral shaking of the support rotating shaft axis caused by the movement of the rotating mechanism during the pressing process, thereby improving the stability during actual application.

[0036] A two-way adjustable pressure testing fixture pressing device, as shown in Figure 2 It comprises a supporting mechanism 1, a driving mechanism 2 and a pressing mechanism 3, the driving mechanism 2 is arranged on the supporting mechanism 1 and connected with the pressing mechanism 3 to drive the pressing mechanism 3, and the pressing mechanism 3 comprises:

[0037] The first connecting rod 3-1 and the supporting shaft 3-2 are coaxially connected, one end of the supporting shaft 3-2 is inserted into the first connecting rod 3-1 and rotates around the axis;

[0038] The rotating block 3-6 is provided with threaded holes on two opposite sides, the supporting shaft 3-2 passes through the rotating block 3-6, at least one protrusion is arranged on the supporting shaft 3-2, and a first cavity 3-6-1 matched with the protrusion is arranged on the rotating block 3-6; in the process of rotation of the supporting shaft 3-2, the torque for driving the rotating block 3-6 to rotate is formed by the force exerted on the first cavity 3-6-1 by the protrusion;

[0039] The first pressure head 3-3 and the second pressure head 3-4 are respectively detachably installed in the threaded holes and adjust the height of the protrusion from the surface of the rotating block 3-6 by the depth inserted into the threaded hole.

[0040] By arranging the first connecting rod 3-1 and the supporting shaft 3-2, the positions of the first pressure head 3-3 and the second pressure head 3-4 can be exchanged, so that the switching of the two pressure heads can be realized quickly, and the pressing of the wrapping piece can be realized by switching the first pressure head 3-3 and the second pressure head 3-4 in the detection of the wrapping piece with double thickness, without the need of disassembling and assembling the pressing device, so that the efficiency is improved and the volume is reduced.

[0041] Further, in some embodiments, the pressing mechanism 3 further comprises a buffer spring, a baffle is arranged on one end of the supporting shaft 3-2 away from the first connecting rod 3-1, a cylindrical second cavity 3-6-2 is arranged in the rotating block 3-6, the buffer spring is located in the second cavity 3-6-2, is sleeved on the supporting shaft 3-2, and one end of the buffer spring is supported on the baffle and the other end of the buffer spring is supported on the inner wall of the second cavity 3-6-2. Specifically, the inner wall is a cylindrical bottom inner wall.

[0042] By configuring the spring, the overall structure can be prevented from being loose due to the axial shaking of the supporting shaft 3-2 caused by the activity of the rotating mechanism during the pressing process, thereby improving the stability in actual application.

[0043] Further, in some embodiments, the pressing mechanism 3 further comprises two locking nuts 3-5, which are sleeved on the first pressing head 3-3 and the second pressing head 3-4 respectively, and are used to fix the depth of the first pressing head 3-3 and the second pressing head 3-4 inserted into the threaded hole.

[0044] By fixing the insertion depth of the first pressing head 3-3 and the second pressing head 3-4 by the locking nut 3-5, the extension length of the pressing head is solidified, and the stability is improved.

[0045] In the embodiment, two protrusions are arranged symmetrically with respect to the axis of the supporting shaft 3-2. The two protrusions can reduce the lateral moment borne by a single protrusion, thereby improving the strength.

[0047] The first pressing portion and the second pressing portion are both in the shape of a circular truncated cone.

[0048] The structure of the driving mechanism 2 can be the same as that of the prior art, comprising an L-shaped support 2-1, a wrench rod 2-3, and a main rotating frame 2-2. The wrench rod 2-3 is in the shape of a straight plate. The main rotating frame 2-2 comprises a first connecting rod, a second connecting rod, and a connecting portion.

Specifically, the wrench rod 2-3 is pulled to rotate, so as to drive the whole main rotating frame 2-2 to rotate around the fulcrum on the L-shaped support (i.e. the rotating connection point of the main rotating frame 2-2 and the L-shaped support), thereby achieving pressing.

[0050] In addition, in the embodiment, the connecting portion connects the first connecting rod 3-1 through a fixing screw, a sheath is sleeved on the hand-held portion, and the driving mechanism 2 is detachably connected to the supporting mechanism 1. Specifically, the sheath can be made of wood, plastic or other materials.

[0051] In use, since the first pressing head 3-3 and the second pressing head 3-4 are configured, the depths at which the two pressing heads are inserted into the rotating block 3-6 can be different, and the materials can also be different, so that when it is necessary to detect the double-layer thickness of a wrapped piece, different pressing heads can be used through rotation, so that whether the material or the depth of the pressing head can be quickly switched without the need for reassembly. The upper and lower pressing heads have a fixed pressing distance, a positioning rotating shaft is added in the middle, and the pressing conflict caused by the different pressing distances required by the double-layer wrapped piece is solved by the rotating shaft.
