Description

Technical Field

[0001] This utility model relates to the field of longitudinal clamping force gauge technology, and more specifically, it relates to a longitudinal clamping force gauge. Background Technology

[0002] A longitudinal clamping force gauge is a tool used to detect and measure the clamping force exerted on a workpiece in the longitudinal direction. It is widely used in manufacturing, machining, and automotive industries, primarily to ensure that the clamping force applied to a workpiece during assembly, processing, or testing meets design requirements.

[0003] Existing longitudinal pressure gauges, when performing longitudinal pressure testing on workpieces, are mainly designed for a specific type of workpiece and cannot flexibly test workpieces of different types and sizes. For example, the longitudinal clamping force gauge provided in Chinese patent document CN206531726U is not convenient for flexibly testing longitudinal clamping force at different positions of the workpiece. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a longitudinal clamping force gauge to solve the technical problems mentioned in the background art, that the longitudinal clamping force gauge cannot flexibly detect workpieces of different models and sizes, and is not convenient for flexibly detecting longitudinal clamping force at different positions of the workpiece.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A longitudinal clamping force gauge includes a first slide rail and a second slide rail. A sliding seat is symmetrically arranged between the first and second slide rails. A mounting bracket is provided on the side of each sliding seat near the first slide rail. The mounting bracket is L-shaped, and each mounting bracket has two sliders symmetrically and slidably adjustable. A clamping column is threaded onto each slider. A clamping block is mounted on the bottom end of each clamping column via a bearing, and an adjustment knob is provided on the top end. A support frame is provided on the first slide rail, and a support beam is provided on the support frame. A mounting block is slidably adjustable on the support beam. An electric push rod is provided on the mounting block, and a mounting seat is provided at the bottom end of the electric push rod. A pressure detector is provided at the bottom end of the mounting seat, and a clamping plate is provided at the bottom end of the pressure detector.

[0009] The present invention is further configured such that a first sliding groove is provided on the sliding seat, and the sliding seat is slidably installed on the corresponding first slide rail and second slide rail through the first sliding groove. A first locking member is threaded on one side of the sliding seat, and the inner end of the first locking member abuts against the first slide rail. The sliding seat can be flexibly adjusted on the first slide rail and the second slide rail through the first sliding groove, thereby supporting and pressing the workpieces of different models and sizes. When adjusted to a suitable position, the first locking member is tightened, thereby locking and fixing the sliding seat on the first slide rail.

[0010] The present invention is further configured such that a second sliding groove is provided at the bottom end of the support frame, and the support frame is slidably mounted on the first slide rail through the second sliding groove. A second locking member is threaded on one side of the support frame, and the inner end of the second locking member abuts against the side wall of the first slide rail. The second sliding groove allows for flexible adjustment of the support frame on the first slide rail. After adjustment to a suitable position, tightening the second locking member can lock and fix the support frame on the first slide rail.

[0011] The present invention is further configured such that a first adjustment groove is provided on the mounting bracket, and the slider is slidably located in the first adjustment groove. The slider can be slidably limited and installed in the first adjustment groove by the setting of the first adjustment groove.

[0012] The present invention is further configured such that limiting slide grooves are provided on both sides of the inner wall of the first adjustment groove, and limiting slide blocks are provided on both sides of the slider. The limiting slide blocks slide within the limiting slide grooves. When the slider moves within the first adjustment groove, it will drive the limiting slide blocks to move within the limiting slide grooves. The sliding limiting cooperation between the limiting slide blocks and the limiting slide grooves can improve the installation and movement stability of the slider within the first adjustment groove.

[0013] The present invention is further configured such that a second adjustment groove is provided on the supporting crossbeam, and the mounting block is slidably located in the second adjustment groove. The second adjustment groove enables the mounting block to be slidably and adjustablely installed on the supporting crossbeam.

[0014] The present invention is further configured such that the second adjustment groove extends outward to form a limiting groove, and the side wall of the mounting block extends outward to the limiting groove to form a limiting block. The limiting block slides within the limiting groove. The cooperation between the limiting groove and the limiting block can improve the movement stability of the mounting block within the second adjustment groove.

[0015] The present invention is further configured such that a locking pin is threaded on the limiting block, the locking pin extends to the outside of the limiting groove, and a locking knob is provided thereon. Tightening the locking knob causes the locking pin to rotate, and the locking pin moves inward within the limiting block, thereby pressing and fixing the locking knob against the side wall of the supporting beam, thus achieving the locking and fixing of the limiting block within the limiting groove, and thus achieving the locking and fixing of the mounting block within the second adjusting groove.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a longitudinal clamping force gauge, which has the following beneficial effects:

[0018] 1. This utility model includes a first slide rail, a second slide rail, a sliding seat, and a mounting bracket. A clamping block is mounted on the mounting bracket via a slider and a clamping column. The position of the sliding seat on the first and second slide rails is adjusted to ensure a suitable distance between the two sets of sliding seats. Then, the first locking element is tightened to lock the sliding seat in place. The workpiece to be tested is placed between the two sets of sliding seats. Next, the position of the slider in the first adjustment groove is adjusted to a suitable position. Then, the adjustment knob is tightened, causing the clamping column to descend with the clamping block, clamping the workpiece to be tested. This allows for flexible adjustment of the support and clamping positions according to the size of the workpiece, improving the flexibility of longitudinal pressure testing.

[0019] 2. This utility model uses a support frame, mounting beam, and mounting block to install an electric push rod. A pressure testing instrument is positioned below the electric push rod. After the workpiece to be tested is pressed and fixed as described above, the position of the support frame on the first slide rail can be adjusted to a suitable position. Then, the second locking element is tightened to lock the support frame on the first slide rail. Next, the position of the mounting block in the second adjustment groove is adjusted so that the pressure plate is in the testing position. Then, the locking knob is tightened, causing the locking knob to move inward with the locking pin, thus locking the mounting block in the second adjustment groove. Finally, the electric push rod is controlled to lower the mounting base, pressure testing instrument, and pressure plate, applying longitudinal pressure to the workpiece to be tested, thereby detecting the longitudinal clamping force of the workpiece. The detected value can be fed back through the pressure testing instrument.

[0020] 3. When it is necessary to detect different pressure positions of the workpiece, it can be achieved by adjusting the position of the sliding seat on the first slide rail and the second slide rail, or by adjusting the position of the support frame on the first slide rail and the position of the mounting block in the second adjustment groove, so that the longitudinal clamping force of different positions of the workpiece can be flexibly detected.
