Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clamping tools, in particular to a detection clamp and a detection device. BACKGROUND

[0002] When performing a magnetic powder or penetration detection test, the test piece is generally placed directly in a holding tray, and then the local weld of the test piece is detected, and then the angle or position is manually changed for detection of other parts until all the test welds are completely detected.

[0003] The entire detection process has the following defects: (1) it needs to be moved several times, which is time-consuming and laborious, and the detection efficiency is low. (2) If the operation is unqualified, it may cause accidental injury or risk of injury. (3) During the detection process, manually adjusting the angle or position of the test piece will also reduce the detection efficiency and potential safety hazards.

[0004] Therefore, there is an urgent need for a detection clamp and a detection device to solve the technical problems existing in the prior art to some extent. SUMMARY

[0005] The purpose of the present application is to provide a detection clamp and a detection device that can improve the detection efficiency while ensuring safety to some extent.

[0006] The present application provides a detection clamp, comprising a support member, a first clamping member, a second clamping member, and an adjusting member.

[0007] The support member has support portions arranged at intervals along a first direction; the first clamping member and the second clamping member are respectively arranged on the support portions, and a clamping space for clamping a test piece is formed between the first clamping member and the second clamping member.

[0008] The adjusting member is connected to the first clamping member or the second clamping member, which can drive the first clamping member to move towards or away from the second clamping member, or drive the second clamping member to move towards or away from the first clamping member, to adjust the size of the clamping space, so that the test piece is clamped in the clamping space.

[0009] When the clamping space has a preset size that can clamp the test piece, the first clamping member or the second clamping member is driven to rotate, which can drive the test piece to rotate to adjust the detection angle of the test piece.

[0010] Further, the first clamping member comprises a first clamping disc and a first driving rod connected with the first clamping disc; the adjusting member comprises a sleeve and a locking piece.

[0011] The sleeve is threadedly arranged on the first driving rod, and an outer wall of the sleeve is fixed to the support portion through a bearing.

[0012] Driving the sleeve to rotate can make the first clamping disc move towards or away from the second clamping member to adjust the size of the clamping space.

[0013] When the size of the clamping space reaches the preset size, the locking piece penetrates through the sleeve and abuts against the first driving rod, so that the sleeve and the first driving rod are integrated; after the sleeve and the first driving rod are integrated, driving the first driving rod to rotate can drive the to-be-inspected piece to rotate through the first clamping disc.

[0014] Further, the first clamping member comprises a driving handle.

[0015] The first driving rod protrudes from the sleeve, and the driving handle is arranged on the part of the first driving rod protruding from the sleeve.

[0016] After the sleeve and the first driving rod are integrated, driving the driving handle can drive the first driving rod to rotate.

[0017] Further, the second clamping member comprises a second clamping disc and a second driving rod connected with the second clamping disc.

[0018] The second driving rod is fixed to the support portion through a bearing.

[0019] Further, a clamping groove is arranged on the end face of the first clamping disc and the second clamping disc facing each other; the clamping groove comprises an annular groove portion and a straight-through groove portion.

[0020] The annular groove portion is arranged at the center of the first clamping disc and the second clamping disc and is annular, so that the first clamping disc and the second clamping disc can clamp the to-be-inspected piece in a circular tube structure.

[0021] The straight-through groove portion penetrates through the center of the annular groove portion and penetrates through the two side walls of the first clamping disc and the second clamping disc opposite to each other, so that the first clamping disc and the second clamping disc can clamp the to-be-inspected piece in a plate structure.

[0022] In the technical scheme, further, rubber pads are attached to the side walls of the annular groove and the straight-through groove to prevent friction between the to-be-inspected piece and the first clamping disc and the second clamping disc.

[0023] In the technical scheme, further, the support member comprises support plates that can serve as the support portions.

[0024] The support member comprises two support plates that are arranged along the first direction.

[0025] The first clamping member and the second clamping member are arranged on the support plates, respectively.

[0026] In the technical scheme, further, the support member further comprises a bottom plate, and the two support plates are arranged along the first direction on the bottom plate.

[0027] The application further provides a detection device comprising the detection clamp.

[0028] Compared with the prior art, the application has the following beneficial effects:

[0029] The application provides a detection clamp comprising a support member, a first clamping member, a second clamping member and an adjusting member.

[0030] The support member has support portions arranged along a first direction; the first clamping member and the second clamping member are arranged on the support portions, respectively, and a clamping space for clamping a to-be-inspected piece is defined between the first clamping member and the second clamping member.

[0031] The adjusting member is connected to the first clamping member or the second clamping member and can drive the first clamping member to move towards or away from the second clamping member or drive the second clamping member to move towards or away from the first clamping member to adjust the size of the clamping space so that the to-be-inspected piece is clamped in the clamping space.

[0032] When the clamping space has a preset size capable of clamping the to-be-inspected piece, the first clamping member or the second clamping member is driven to rotate, which can drive the to-be-inspected piece to rotate to adjust the detection angle of the to-be-inspected piece.

[0033] In summary, the detection clamp has the advantages of simple structure, low manufacturing cost and strong versatility. The size of the clamping space is adjusted by the adjusting member, so that the detection clamp can adapt to detection pieces of different length specifications. Secondly, the detection personnel do not need to manually rotate the detection piece during the entire operation process, ensuring the safety of the detection personnel during the detection process. Finally, whether adjusting the size of the clamping space or adjusting the rotation angle of the detection piece is completed in an automated manner, which improves the work efficiency to a certain extent compared with the existing manual rotation.

[0034] The application also provides a detection device comprising the detection clamp described above. Therefore, the detection device has all the beneficial effects of the detection clamp described above, which will not be elaborated here. BRIEF DESCRIPTION OF DRAWINGS

[0063] At present, when carrying out magnetic powder or penetration detection test, there are problems of low detection efficiency and safety hidden danger by using existing structure or method. In order to solve the technical problem, the application provides a detection clamp, and the following Figures 1-15 The application provides a detection clamp.

[0064] The detection clamp in the embodiment comprises a supporting member 1, a first clamping member 2, a second clamping member 3 and an adjusting member 4.

[0065] The supporting member 1 has supporting portions arranged at intervals along a first direction 5; according to the Figure 2The first direction 5 refers to the length direction of the support member 1. Alternatively, the support member is provided with two support portions, i.e., a first support portion 101 and a second support portion 102, which are arranged in the length direction of the support member 1. Specifically, the first clamping member 2 is arranged on the first support portion 101, and the second clamping member 3 is arranged on the second support portion 102. The first clamping member 2 and the second clamping member 3 define a clamping space 207 for clamping the test piece 7.

[0066] The adjusting member 4 is connected to the first clamping member 2 or the second clamping member 3. In this embodiment, the adjusting member 4 is connected to the first clamping member 2, which will be described in detail. The adjusting member 4 can drive the first clamping member 2 to move towards or away from the second clamping member 3. When the adjusting member 4 drives the first clamping member 2 to move towards the second clamping member 3, the size of the clamping space 207 can be reduced. When the adjusting member 4 drives the first clamping member 2 to move away from the second clamping member 3, the size of the clamping space 207 can be increased. That is, the size of the clamping space 207 can be adjusted by the adjusting member 4, so as to adapt to test pieces 7 of different length specifications.

[0067] When the clamping space 207 has a preset size capable of clamping the test piece 7, i.e., when the size of the clamping space 207 reaches the preset size capable of clamping the test piece 7, the first clamping member 2 or the second clamping member 3 is driven to rotate, which can drive the test piece 7 to rotate, so as to adjust the detection angle of the test piece 7.

[0068] In summary, the detection clamp has the advantages of simple structure, low manufacturing cost, and strong versatility. The size of the clamping space 207 can be adjusted by the adjusting member 4, so as to adapt to test pieces 7 of different length specifications. Second, the detection personnel does not need to manually rotate the test piece 7 during the entire operation process, which ensures the safety of the detection personnel during the detection process. Finally, whether the size of the clamping space is adjusted or the rotation angle of the test piece 7 is adjusted is completed in an automatic manner, which improves the work efficiency to a certain extent compared with the existing manual rotation.

[0069] In this embodiment, the first clamping member 2 is arranged on the first support portion 101, and the second clamping member 3 is arranged on the second support portion 102. Figure 17 As shown in FIG. 1, the first clamping member 2 includes a first clamping disc 201 and a first driving rod 202 connected to the first clamping disc 201. Preferably, the first clamping disc 201 is in the shape of a disc. The first clamping disc 201 is fixed to the end of the first driving rod 202. Alternatively, the first driving rod 202 is integrally formed with the first clamping disc 201, which improves the stability of the first clamping member 2 to a certain extent.

[0070] In combination with FIG. 1, Figures 13-15 and in combination with FIG. 2, Figure 5 and FIG. 3.Figure 6 As shown, the adjusting member 4 comprises a sleeve 401 and a locking member 402. The inner side wall of the sleeve 401 is provided with an internal thread, and the outer side wall of the first driving rod 202 is provided with an external thread which is matched with the internal thread, so that the sleeve 401 and the first driving rod 202 can be threadedly connected. Specifically, the sleeve 401 and the first driving rod 202 have a relative movement relationship. Specifically, when the sleeve 401 is rotated at the fixed position on the first driving rod 202, the first driving rod 202 will move in the first direction 5; when the first driving rod 202 moves in the first direction 5, the first clamping disc 201 will move in the first direction 5 since the first clamping disc 201 is fixed on the first driving rod 202. In addition, since the second clamping member 3 is fixed, when the sleeve 401 is rotated, the clamping space 207 between the first clamping disc 201 and the second clamping member 3 will be changed until the clamping space 207 has a preset clamping size.

[0071] In combination with Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , and referring to Figure 11 and Figure 12 , the outer side wall of the sleeve 401 is fixed to the support part by the bearing 303; that is, when the sleeve 401 is rotated, the first support part 101 is still fixed; that is, the bearing 303 ensures the completeness and feasibility of the device.

[0072] In combination with Figure 1 , Figure 5 , Figure 6 and Figure 13 , a through hole 403 is formed in the sleeve 401 for the locking member 402 to pass through. Optionally, the locking member 402 is a locking screw. When the size of the clamping space 207 reaches the preset size, at least part of the locking screw can pass through the through hole 403 of the sleeve 401 perpendicularly and abut against the first driving rod 202. Further, since the locking screw passes through the sleeve 401 and abuts against the first driving rod 202, the sleeve 401 and the first driving rod 202 can be integrated at this time, that is, they are connected together by the locking screw, and no relative movement occurs between them. Then, when the sleeve 401 and the first driving rod 202 are integrated, when the first driving rod 202 is driven to rotate, no relative movement occurs between the sleeve 401 and the first driving rod 202, the first driving rod 202 and the sleeve 401 rotate at the same time, the first clamping disc 201 can drive the object 7 to rotate, and the detection rotation angle of the object 7 is adjusted.

[0073] In actual use, first, the sleeve 401 is rotated to move the first clamping disc 201 towards or away from the second clamping member 3 to adjust the size of the clamping space 207; then the piece 7 to be inspected is placed in the clamping space 207; then, the sleeve 401 is continuously rotated to make the clamping space 207 firmly clamp the piece 7 to be inspected in the clamping space 207; then, the locking piece 402 is passed through the through hole 403 and abuts against the first driving rod 202, so that the sleeve 401 and the first driving rod 202 are integrated; finally, the first driving rod 202 is rotated to rotate the first clamping disc 201, and when the first clamping disc 201 rotates, the piece 7 to be inspected is rotated to adjust the detection angle of the piece 7 to be inspected.

[0074] It is worth noting that in the above-mentioned process, the sleeve 401 is rotated to move the first driving rod 202 in the first direction 5; however, in actual use, the first driving rod 202 can also be directly screwed on the sleeve 401.

[0075] In this embodiment, as shown in Figure 4 and Figure 7 , the first clamping member 2 includes a driving handle 203; the first driving rod 202 protrudes from the sleeve 401, and the driving handle 203 is arranged on the part of the first driving rod 202 protruding from the sleeve 401; after the sleeve 401 and the first driving rod 202 are integrated, driving the driving handle 203 can drive the first driving rod 202 to rotate.

[0076] Specifically, when the sleeve 401 is relatively free from the first driving rod 202, that is, when the locking piece 402 does not lock the sleeve 401 to the first driving rod 202, the driving handle 203 is held and the first driving rod 202 is driven to rotate, so that the first clamping disc 201 is moved towards or away from the second clamping member 3 to change the size of the clamping space 207. In addition, when the locking piece 402 locks the sleeve 401 and the first driving rod 202 into an integrated structure, the driving handle 203 is held and the first driving rod 202 is driven to rotate to adjust the angle of the first clamping disc, thereby adjusting the rotation angle of the piece 7 to be inspected.

[0077] Preferably, the driving handle 203 is a rod-shaped structure with a specification of φ10×60.

[0078] In this embodiment, as shown in Figures 1-7 and referring to Figure 16 , the second clamping member 3 includes a second clamping disc 301 and a second driving rod 302 connected with the second clamping disc 301; specifically, the second clamping disc 301 is arranged at the end of the second driving rod 302.

[0079] In addition, the second driving rod 302 is fixed to the support portion through a bearing 303; that is, the second clamping disc 301 can rotate on the second support portion 102 through the action of the second driving rod 302 and the bearing 303; that is, when the first driving rod 202 drives the first clamping disc 201 to rotate, since the first clamping disc 201 and the second clamping disc 301 clamp the test piece 7 therebetween, the test piece 7 and the second clamping disc 301 will also rotate with the first clamping disc 201, thereby ensuring the rotational balance of the test piece 7 in the axial direction thereof.

[0080] In this embodiment, in combination with Figure 2 As shown in the drawings, the first clamping disc 201 and the second clamping disc 301 are provided with clamping grooves 204 on the end faces facing each other, which are used to clamp the test piece 7 to prevent the test piece 7 from falling out of the clamping space 207. Specifically, the clamping grooves 204 include annular groove portions 205; wherein the annular groove portions are provided at the center positions of the first clamping disc 201 and the second clamping disc 301 and are annular. In combination with Figure 6 and Figure 7 As shown in the drawings, the annular groove portions 205 can enable the first clamping disc 201 and the second clamping disc 301 to clamp the test piece 7 in a circular tube structure.

[0081] In addition, the clamping grooves 204 also include straight-through groove portions 206, which pass through the centers of the annular groove portions in the second direction 6 and penetrate the two side walls of the first clamping disc 201 and the second clamping disc 301 opposite to each other. In combination with Figure 4 and Figure 5 As shown in the drawings, the first clamping disc 201 and the second clamping disc 301 can clamp the test piece 7 in a plate structure.

[0082] The above-mentioned second direction 6, in combination with Figure 3 As shown in the drawings, refers to the width direction of the support member 1. Considering that the first clamping disc 201 and the second clamping disc 301 are both circular, and since the annular groove portions are provided at the center positions of the first clamping disc 201 and the second clamping disc 301, as long as the extending direction of the straight-through groove portions 206 is in the radial direction of the first clamping disc 201, it can be achieved.

[0083] In this embodiment, the side walls of the annular groove portions 205 and the straight-through groove portions 206 are provided with rubber pads, which prevent friction between the test piece 7 and the first clamping disc 201 and the second clamping disc 301. That is, it can avoid the first clamping disc 201 and the second clamping disc 301 from being in hard contact with the test piece 7 and causing scratches.

[0084] In this embodiment, in combination with Figures 8-10As shown, the support member 1 comprises support plates that can serve as support portions; two support plates are provided, namely a first support plate 103 and a second support plate 104, which are arranged in a spaced apart manner along the first direction 5.

[0085] Further, mounting holes 106 are formed at positions opposite to the first support plate 103 and the second support plate 104, the sleeve 401 in the first clamping member 2 is mounted in the mounting hole 106 of the first support plate 103 through a bearing 303, and the second driving rod 302 in the second clamping member 3 is mounted in the mounting hole 106 of the second support plate 104 through a bearing 303. The above-mentioned bearing 303 mainly serves to bear and rotate the first clamping disc 201 and the second clamping disc 301.

[0086] Further, the support member 1 further comprises a bottom plate 105, and the two support plates are arranged in a spaced apart manner along the first direction 5 on the bottom plate 105. The bottom plate functions to support the first support plate 103 and the second support plate 104. Alternatively, the first support plate 103 and the second support plate 104 are fixed to the bottom plate by welding, so as to ensure the integrity of the entire support member 1 and to ensure the support strength. Alternatively, the first support plate 103, the second support plate 104 and the bottom plate 105 are integrally formed, so as to ensure the integrity of the entire support member 1 and to ensure the support strength.

[0087] It is worth noting that, considering that the present application is used for magnetic powder detection, there is a possibility of magnetization, so all the above-mentioned components in the present application are preferably made of stainless steel, which not only avoids magnetization of the detection clamp, but also makes the rigidity of the entire detection clamp meet the use requirements.

[0088] If the cost of the above-mentioned stainless steel material is high, 3D printing technology can also be used to manufacture an ABS material clamp by a scale of 1:2. The use equipment is a desktop 3D printer, and the principle is FDM technology. The established three-dimensional model is imported into the printing software in STL format, and the model needs to be layered during the printing process, and the printing is completed layer by layer.

[0089] In summary, the use steps of the detection clamp are as follows:

[0090] Step 100: Rotate the locking member 402 to allow the sleeve 401 and the first driving rod 202 to rotate freely. Step 200: Hold the driving handle 203 and rotate the first driving rod 202 of the first clamping disc 201 to adjust the distance between the first clamping disc 201 and the second clamping disc 301.

[0091] Step 300: the plate-shaped structure of the test piece 7 is clamped in the straight-through slot 206 of the first clamping disc 201 and the second clamping disc 301, or the circular tube-shaped test piece 7 is clamped in the annular slot 205 of the first clamping disc 201 and the second clamping disc 301.

[0092] Step 400: the first driving rod 202 of the right clamping plate is reversely rotated by means of the driving handle 203, and the test piece 7 is clamped.

[0093] Step 500: finally, the sleeve 401 is fastened relative to the first driving rod 202 by rotating the locking member 402, and thus the test piece is clamped.

[0094] Step 600: the starting handle is held, and the detection angle of the flat plate to the test piece 7 or the rotation of the circular tube to the test piece is adjusted by positive rotation or reverse rotation, so as to complete the detection work of the welds in the whole test piece 7.
