Description

Technical Field

[0001] This utility model relates to the field of cutting fixture technology, specifically, it demonstrates a cutting fixture for sample testing data. Background Technology

[0002] After the membrane material products are manufactured, they need to be sampled and subjected to mechanical performance tests according to the relevant industry testing standards. Membrane materials are generally thin and prone to wrinkling. When manually cutting sample strips, the operation is laborious, and it is easy to produce gaps and unevenness in the sample strips. Moreover, it is impossible to accurately guarantee that the length of each cut is consistent, which cannot effectively prepare samples and affects the accuracy of test data. Utility Model Content

[0003] The purpose of this invention is to provide a cutting fixture for sample testing data that offers good flexibility.

[0004] The technical solution is as follows:

[0005] A sample test data cutting fixture, comprising:

[0006] The cutting head is hollow inside and open at the front end;

[0007] Handheld column, which is connected to one side of the bottom end of the cutting head;

[0008] A cutting component, which is located inside the cutting head and can be exposed outward from the front opening of the cutting head;

[0009] The cutting assembly includes at least one pair of displacement seats arranged in a left-right mirror configuration. Each displacement seat is provided with a nut plate. The two displacement seats are respectively connected to a bidirectional lead screw through the nut plates via a common thread. The bidirectional lead screw is driven to rotate by a horizontal lead screw motor. When the bidirectional lead screw rotates, the two nut plates move in opposite directions on the bidirectional lead screw.

[0010] The cutting assembly also includes a vertical transmission screw rotatably disposed inside the other side of the displacement seat. The vertical transmission screw is driven to rotate by a vertical screw motor. A sliding block is threaded on the vertical transmission screw. A hinge block is hinged to the outside of the sliding block. A cutting blade is connected to the hinge block outward. The middle two sides of the cutting blade are also hinged between a pair of extension plates. The pair of extension plates are disposed on the displacement seat.

[0011] The cutting assembly further includes a horizontally arranged guide shaft, and both nut plates on the pair of displacement seats can be movably fitted onto the guide shaft. This improves the positional accuracy of the displacement seats during lateral movement and prevents them from shaking or vibrating.

[0012] Furthermore, the guide shaft and the bidirectional lead screw are arranged side by side on the nut plate. The side-by-side guide shaft and bidirectional lead screw provide a stable support for the displacement seat.

[0013] The hinge block has a straight shaft on its outer side and an inner groove shaft on the side end of the cutting blade. The straight shaft is slidably embedded inside the inner groove shaft. This allows for easy adjustment of the cutting blade's pitch angle, enabling precise adjustment of the cutting angle and greatly improving the usability and flexibility of the cutting assembly.

[0014] The top surface of the cutting head is provided with a scale near the opening at the front end of the cutting head. During the left and right sliding of the cutting blade, the sliding width can be observed through the relevant scale lines on the scale.

[0015] The cutting head has at least three equidistantly distributed cameras on its bottom surface. These cameras at the bottom of the cutting head monitor the cutting position of the upper cutting blade in real time.

[0016] Furthermore, a display panel is provided on the top surface of the cutting head, and an external cable is provided at the bottom of the handheld column. Thus, the image captured by the camera can be transmitted to the display panel for real-time monitoring via a signal connection, and the external cable can be connected to a corresponding controller to control the cutting components.

[0017] The handheld column is covered with an anti-slip pad. This pad effectively prevents the handheld column from slipping out of the hand during use, improving safety.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By using a nut plate, a bidirectional lead screw, and a horizontal lead screw motor, the cutting width can be precisely controlled. Multiple horizontal lead screw motors work together, allowing multiple displacement seats to flexibly adjust their spacing to meet diverse cutting needs. Multiple sample strips of the same size can be cut at once. After the width is adjusted, the cutting angle of the cutting blade can be easily adjusted by using a vertical transmission lead screw, a vertical lead screw motor, a sliding block, and a hinge block. This allows for fine adjustment of the cutting blade angle and greatly improves the applicability and flexibility of the cutting component.

[0020] 2. By equipping the cutting head with scale marks and a camera, the cutting width and position of the fixture can be detected, ensuring that the cutting work is accurate and error-free.

[0021] 3. The addition of anti-slip pads to the handheld column effectively prevents slippage and improves the safety of jig operation. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] Example 1:

[0031] This utility model provides a cutting fixture for sample test data to solve the technical problems mentioned in the background art. Specifically, as shown in the following embodiment... Figures 1 to 4As shown. The fixture includes a cutting head 1, which is hollow inside and has an open front end. A handheld post 2 is provided on one side of the bottom end of the cutting head 1. The angle between the handheld post 2 and the cutting head 1 can be adjusted, either to a right angle or an obtuse angle, depending on the comfort of actual use. The connection between the handheld post 2 and the cutting head 1 can be a relatively direct welding connection. A cutting component 3 is arranged in the internal space of the cutting head 1, and the cutting output end of the cutting component 3 can be exposed outward from the front opening of the cutting head 1.

[0032] In this embodiment, the cutting component 3 includes three pairs of two displacement seats 31 arranged in a left-right mirror configuration, resulting in a total of six displacement seats arranged in pairs from the outside in. These six displacement seats are arranged side by side, and each displacement seat 31 is provided with a nut plate 32. The nut plates of the three pairs of displacement seats are arranged in an upper, middle, and lower manner to ensure that they do not interfere with each other. The two displacement seats 31 corresponding to each other are respectively connected to a bidirectional lead screw 33 by the nut plate 32 through a common thread, resulting in a total of three bidirectional lead screws. The bidirectional lead screws 33 are driven to rotate by a horizontal lead screw motor 331. When the bidirectional lead screws 33 rotate, the two nut plates 32 move in opposite directions on the bidirectional lead screws 33. That is, the spacing between the six displacement seats can be flexibly adjusted by these three bidirectional lead screws without mutual interference, thus ensuring that the spacing between each pair of displacement seats is equal.

[0033] The cutting assembly 3 also includes a vertical transmission screw 34 rotatably disposed inside the other side of the displacement seat 31. The vertical transmission screw 34 and the bidirectional screw 33 are respectively located on both sides of the displacement seat 31. The vertical transmission screw 34 is driven to rotate by a vertical screw motor 341. A sliding block 35 is threaded on the vertical transmission screw 34, that is, the vertical screw motor 341 controls the up and down displacement of the sliding block 35. A hinge block 36 is hinged to the outer side of the sliding block 35. A cutting blade 37 is connected to the outer side of the hinge block 36. The middle two sides of the cutting blade 37 are also hinged between a pair of extension plates 38. The pair of extension plates 38 are disposed on the displacement seat 31, that is, the cutting blade can swing up and down relative to the pair of extension plates. When the sliding block moves up, the tail of the cutting blade tilts up and the head of the cutting blade moves down. When the sliding block moves down, the tail of the cutting blade falls down and the head of the cutting blade moves up, thereby realizing the change of the pitch angle of the cutting blade.

[0034] By incorporating a nut plate, a bidirectional lead screw, and a horizontal lead screw motor, the cutting width can be precisely controlled. Multiple horizontal lead screw motors work in concert, allowing multiple displacement seats to flexibly adjust their spacing until the spacing between any two displacement seats is consistent, meeting diverse cutting needs. After the width adjustment is complete, the cutting angle of the cutting blade can be easily adjusted through the vertical transmission lead screw, vertical lead screw motor, sliding block, and hinge block, achieving fine adjustment of the cutting blade angle and greatly improving the applicability and flexibility of the cutting assembly.

[0035] In this embodiment, the cutting assembly 3 also includes a horizontally arranged guide shaft 39, and the nut plates 32 on a pair of displacement seats 31 can be movably sleeved on the guide shaft 39. By adding the guide shaft, the positional accuracy of the displacement seats when moving left and right is improved, and the shaking or wobbling of the displacement seats is avoided.

[0036] It is worth noting that the guide shafts 39 and the bidirectional lead screws 33 on the two corresponding displacement seats 31 are arranged side by side on the two nut plates 32, and the guide shafts and bidirectional lead screws arranged side by side provide a stable support for the displacement seats.

[0037] In this embodiment, a straight shaft 361 is provided on the outer side of the hinge block 36, and an inner groove shaft 371 is provided on the side end of the cutting blade 37. The straight shaft 361 is slidably embedded inside the inner groove shaft 371. During the up-and-down swinging of the hinge block and the cutting blade, the straight shaft and the inner groove shaft will slide relative to each other, but they will always remain connected. This allows for easy adjustment of the pitch angle of the cutting blade, enabling fine adjustment of the cutting angle and greatly improving the usability and flexibility of the cutting assembly.

[0038] In this embodiment, an anti-slip pad 21 is provided on the outside of the handheld column 2. The anti-slip pad effectively prevents the handheld column from slipping out of the hand during use, thus improving safety.

[0039] Example 2:

[0040] like Figure 5 and Figure 6 As shown, based on the above embodiment 1, the top surface of the cutting head 1 may be provided with a scale mark 11 near the opening at the front end of the cutting head. The center of the scale mark coincides with the center of the three pairs of cutting blades, so that the sliding width can be observed through the relevant scale lines on the scale mark during the left and right sliding of the cutting blades.

[0041] In addition, at least three miniature cameras 12 are equidistantly distributed on the bottom surface of the cutting head 1. The cameras at the bottom of the cutting head monitor the cutting position of the upper cutting blade in real time.

[0042] Based on this design, a display panel 13 is provided in the middle of the top surface of the cutting head 1. The camera 12 is electrically connected to the display panel 13, and an external cable 22 is provided at the bottom of the handheld column 2. In this way, the image captured by the camera can be transmitted to the display panel for real-time monitoring via a signal connection, and the external cable is connected to the corresponding controller to control the cutting components accordingly.

[0043] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
