Abstract
Description
Technical Field
[0001] The present application relates to the field of security inspection technology, and in particular to a workpiece clamping device and an inspection vehicle. Background Art
[0002] Before inspecting larger or large workpieces, the workpieces need to be fixed on the inspection platform first, and then the inspection of the workpieces is completed through the cooperation of the radiation source device and the detector device. Since the inspected workpieces are long, large in diameter, and heavy, the fixtures, as devices for lifting and fixing the workpieces on the inspection platform, need to have a certain support strength, and their weight and volume will also be large. Therefore, in general, the fixtures on the inspection platform will not be replaced. At present, there are various types of workpieces, and the security inspection system needs to inspect workpieces of different diameters, so the diameter of the fixture needs to be adjusted to adapt it to the outer surface of the workpiece to be tested.
[0003] In the prior art, during the process of adjusting the fixture, the adjustment position is usually set on the outer periphery of the fixture so that the bearing on the inner periphery can move radially and clamp the workpiece. However, due to the large diameter of the workpiece, the adjustment positions on the outer periphery of the fixture are relatively far from each other, and the working position needs to be moved many times during the adjustment process. In addition, the adjustment mechanism is small and difficult to find; in addition, the adjustment position of the fixture may be at the top farthest from the ground, and the staff or robot needs to be lifted to a position higher than the top of the fixture by a lifting device to adjust the bearing farthest from the ground, making the adjustment process of the fixture very troublesome and time-consuming.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0045] Unless otherwise defined, the technical terms or scientific terms used in this disclosure should be understood by ordinary technicians in the field. "First", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.
[0046] In this document, unless otherwise specified, directional terms such as "upper", "lower", "left", "right", "inner", "outer", etc. are used to indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing the present disclosure, and do not indicate or imply that the device, element or component referred to must have a specific orientation, be constructed or operate in a specific orientation. It should be understood that when the absolute position of the described object changes, the relative positional relationship they represent may also change accordingly. Therefore, these directional terms should not be understood as limiting the present disclosure.
[0047] Before the security inspection of the workpiece, it is necessary to fix the workpiece on the security inspection platform, and then complete the inspection of the workpiece through the cooperation of the radiation source device and the detector device. Since the inspected workpiece is long, large in diameter, and heavy, the fixture, as a device to lift and fix the workpiece on the security inspection platform, needs to have a certain support strength, and its weight and volume will also be large. Therefore, under normal circumstances, the fixture on the security inspection platform will not be replaced. At present, there are various types of workpieces, and the security inspection system needs to inspect workpieces of different diameters, so the diameter of the fixture needs to be adjusted to make it adapt to the outer surface of the workpiece to be tested.
[0048] In the prior art, during the process of adjusting the fixture, the adjustment position is usually set on the outer periphery of the fixture so that the bearing shell on the inner periphery can move radially and clamp the workpiece. However, due to the large diameter of the workpiece, the adjustment positions are usually dispersed at intervals on the outer periphery of the fixture, making the adjustment positions relatively far from each other. During the adjustment process, the staff needs to move the working position many times to drive each adjustment mechanism. The adjustment hole of the adjustment mechanism is generally small and difficult to find.
[0049] In summary, the adjustment may not be completed in one go during the adjustment process, so there is a possibility of back and forth adjustment between multiple adjustment mechanisms, repeated movement of the working position, and the difficulty in finding the adjustment hole, which prolongs the time spent on adjusting the fixture. In addition, the adjustment position of the fixture may be at the top farthest from the ground and at the outer periphery of the fixture, requiring workers or robots to be lifted to a position above the top of the fixture by a lifting device to find the adjustment hole and adjust the corresponding bearing, making the adjustment process of the fixture very troublesome.
[0050] In order to solve the above problems, the present application proposes a workpiece clamping device and an inspection vehicle that can carry and install the workpiece clamping device. The workpiece is placed on the workpiece clamping device of the inspection vehicle. During the adjustment process, the staff can adjust the adjustment mechanisms at multiple different positions at one time, saving adjustment time.
[0051] It should be noted that the workpiece clamping device of the present application is designed for large workpieces or relatively large workpieces, which are characterized by large volume, heavy mass, and long axial length and diameter. The workpiece clamping device of the present application does not limit the appearance shape of large workpieces. For example, large workpieces are usually cylinders or truncated cones, but large workpieces of other shapes that can be applied to the present application to clamp their outer surfaces and adjust the clamping adaptability are also within the protection scope of the present application.
[0052] Refer to the following Figure 1-Figure 7 Describe the workpiece clamping device according to the embodiment of the present application. The present application is explained by taking the large workpiece as a cylinder as a specific embodiment, so the corresponding workpiece clamping device is an annular clamp that matches the cylindrical workpiece.
[0053] Specifically, the workpiece clamping device 100 includes:
[0054] The first clamping member 10 and the second clamping member 20 each include a first surface 101 and a second surface 102 that are oppositely disposed, and a connecting surface 103 that connects the first surface 101 and the second surface 102 .
[0055] refer to Figure 1 The workpiece clamping device 100 is adapted to the shape of the workpiece and can be a fixture of an annular structure, mainly composed of a first clamping member 10 of the upper half ring and a second clamping member 20 of the lower half ring, and the two ends of the two half ring structures are buckled, that is, the two ends of the first clamping member 10 and the two ends of the second clamping member 20 are buckled to form a whole ring. The buckled connection position can be a clamping connection or other connection methods, which are not limited here. Since the length of the workpiece is relatively long, the first clamping member 10 and the second clamping member 20 must have a certain thickness. The thickness here refers to the length extending in the axial direction of the workpiece, that is, the ring width of the annular structure, so that the first clamping member 10 and the second clamping member 20 have at least four surfaces: the inner surface of the annular structure is the first surface 101, the outer surface of the annular structure is the second surface 102, and at least two surfaces connected to the first surface 101 and the second surface 102 are both called connecting surfaces 103. Figure 1 FIG. 1 is a schematic diagram of a simple annular structure defined by four surfaces, so the connecting surfaces 103 are two surfaces facing the axial direction of the workpiece.
[0056] The adjusting mechanism 30 is sleeved on the first clamping member 10 and the second clamping member 20. The adjusting mechanism 30 is used to adjust the bearing bush 40 described below in the radial direction.
[0057] A plurality of bearing pads 40 are arranged circumferentially at intervals along the first surface 101 of the first clamping member 10 and / or the first surface 101 of the second clamping member 20 , and each bearing pad 40 is selectively movable in the radial direction by the adjustment mechanism 30 .
[0058] In a specific embodiment, the bearing bush 40 may be arranged only on the first surface 101 of the first clamp 10, or only on the first surface 101 of the second clamp 20, or simultaneously on the first surface 101 of the first clamp 10 and the first surface 101 of the second clamp 20, and the number of arrangements is not limited. In the embodiment of the present application, a plurality of bearing bushes 40 are arranged, and reference is made to FIG. Figure 1 The bearing bushes 40 are arranged on the first surface 101 of the first clamping member 10 and the first surface 101 of the second clamping member 20. Preferably, the bearing bushes 40 are arranged symmetrically and evenly. Figure 1 It is shown that three bearings 40 are arranged on the first surface 101 of the first clamping member 10, and three bearings 40 are also arranged on the first surface 101 of the second clamping member 20. Each bearing 40 corresponds to an adjustment mechanism 30. During the adjustment process of the adjustment mechanism 30, the corresponding bearing 40 moves in the radial direction of the workpiece, that is, it moves closer to or away from the outer surface of the workpiece during adjustment, so that the clamping degree of the bearing 40 on the workpiece can be adjusted.
[0059] For the convenience of adjustment, the adjustment surface 301 of the adjustment mechanism 30 is attached to the connection surface 103 of the first clamping member 10 or the second clamping member 20. The adjustment surface 301 here refers to the working surface that can adjust the radial position of the bearing bush 40, that is, the staff can adjust the clamping degree of the bearing bush 40 on the workpiece by operating on the adjustment surface 301 of the adjustment mechanism 30. Figure 1 , the adjustment surface 301 is exposed in the axial direction of the workpiece. When adjusting each bearing 40, the staff can easily find the adjustment surface 301 on the adjustment mechanism 30 corresponding to each bearing 40, so that the staff can drive multiple adjustment mechanisms 30 in one working position, which can speed up the speed of the clamping device to adapt to large workpieces and avoid repeated movement of the working position; in addition, since the adjustment surface 301 faces the staff, it is easier to find the adjustment hole on the adjustment surface 301. It should be noted that the adjustment hole here refers to the position that can be operated on the adjustment mechanism 30 to move the bearing 40 in the radial direction.
[0060] According to one embodiment of the present application, the bearing bush 40 is configured to be arc-shaped and has the same axis as the first clamping member 10 or the second clamping member 20 where the bearing bush 40 is located. In other words, the bearing bush 40 can be completely fitted with the first surface 101 of the first clamping member 10 or the first surface 101 of the second clamping member 20, so that the workpiece clamping device 100 can be adapted to the outer surfaces of more types of workpieces to the maximum extent.
[0061] According to one embodiment of the present application, the adjustment mechanism 30 includes: a worm 31, a turbine 32, and a guide sleeve 33. The worm 31 penetrates the connection surface 103 and is fixed on the adjustment surface 301, the turbine 32 is arranged perpendicular to the worm 31, one end 322 of the turbine is meshed with the worm 31, the guide sleeve 33 is sleeved on the turbine 32 and meshed with the other end 321 of the turbine, and the end 323 of the other end of the turbine cooperates with the bearing bush 40 so that the bearing bush 40 can selectively move in the radial direction.
[0062] refer to Figure 2 and Figure 3 The worm 31 passes through the connecting surfaces 103 on both sides and is fixed on the adjusting surface 301. The end 311 of the worm is exposed on the adjusting surface 301. In this way, the worm 31 can be screwed on both connecting surfaces 103. That is, when the workpiece clamping device 100 is installed on the inspection vehicle, it is not necessary to distinguish between the front and back sides. It can be understood that the front side refers to the side of the adjustable bearing 40, and the back side refers to the side of the non-adjustable bearing 40. Under the action of the worm 31, the turbine 32 is driven to rotate, and the guide sleeve 33 moves in the radial direction to make the bearing 40 close to or away from the outer surface of the workpiece.
[0063] It can be understood that in this embodiment, the rotating worm 31 is the source of the radial movement of the drive bearing 40, and an adjustment hole for the end of the worm 31 to pass through is provided on the adjustment surface 301, so that the end of the worm 31 is exposed, and the staff can drive the bearing 40 to move in the radial direction by rotating the worm 31 in the adjustment hole.
[0064] According to one embodiment of the present application, a guide groove 3301 is further provided on the outer surface of the guide sleeve 33 , and a guide block 34 facing the guide groove 3301 is further provided on the adjustment surface 301 . The guide groove 3301 extends in the radial direction, and the guide groove 3301 abuts against the guide block 34 .
[0065] It can be understood that the guide sleeve 33 is a radially movable accessory. In order to allow the guide sleeve 33 to move normally in the radial direction and avoid being disengaged from the other end 321 of the turbine, a guide groove 3301 is provided on the outer surface of the guide sleeve 33. A guide block 34 is provided at a corresponding position, and the guide block 34 cooperates with the guide groove 3301. Figure 3The guide block 34 is fixed on the inner surface of the adjustment surface 301, and the guide block 34 faces the guide groove 3301. It is at least partially inserted into the guide groove 3301, which can prevent the guide sleeve 33 from escaping from the other end 321 of the turbine due to over-adjustment, or from escaping from the other end 321 of the turbine due to the guide sleeve 33 shaking in the circumferential direction of the annular fixture.
[0066] According to one embodiment of the present application, an adapter 50 is further provided between the end of the other end 321 of the turbine and the bearing shell 40 , and the contact position between the adapter 50 and the end of the other end 321 of the turbine is a spherical protrusion 51 .
[0067] It is understandable that, since the outer surface of the workpiece may not be a standard cylinder, that is, its cross section is not circular, and the axis of the workpiece may not coincide with the axis of the workpiece clamping device 100 during the process of placing the workpiece in the workpiece clamping device 100, the bearing bush 40 may not be completely in contact with the outer surface of the workpiece. The present application takes this into consideration and designs an adapter 50 to solve this problem. The contact position between the adapter 50 and the end of the other end 321 of the turbine is a spherical protrusion 51, which can be applied to workpieces placed at various angles. Figure 4 and Figure 5 9 is a cross-sectional view of the adapter 50, which is fixed to the bearing bush 40 by the second bolt 90. After the bearing bush 40 is pushed out radially, it is no longer in contact with the first surface 101 of the first clamp 10 or the first surface 101 of the second clamp 20. The bearing bush 40 can be tilted in any direction by the spherical protrusion 51, so that its surface fits the outer surface of the workpiece, which has a better clamping effect.
[0068] According to an embodiment of the present application, the workpiece holding device further includes: a buffer mechanism, which is disposed between the guide sleeve 33 and the bearing bush 40 .
[0069] It is understandable that, during the placement of the workpiece, the workpiece is first placed on the second clamping member 20 at the lower end, and then the first clamping member 10 at the upper end is engaged. The buffer mechanism plays a buffering role when the workpiece is placed on the second clamping member 20, and also plays a buffering role when the first clamping member 10 is engaged with the second clamping member 20. Of course, for the buffer mechanism of the present application, when an adapter 50 is provided in some embodiments, the buffer mechanism can also serve as an auxiliary to cooperate with the adapter 50 to adjust the tilt direction of the bearing 40.
[0070] According to an embodiment of the present application, the buffer mechanism includes: a fixing member 61 and a buffer member 62. The fixing member 61 is used to fix the bearing bush 40 on the adjustment mechanism 30, and plays a fixing role; the buffer member 62 is used to buffer the contact of the bearing bush 40. Figure 3 and Figure 4The fixing member 61 passes through the bearing shell 40 and the adapter 50 in sequence and is inserted into the positioning hole of the guide sleeve 33. The buffer member 62 is sleeved on the fixing member 61, and the two ends are respectively abutted against the guide sleeve 33 and the bearing shell 40. The fixing member 61 here can be a first bolt, and the buffer member 62 can be a spring, which is sleeved on the first bolt.
[0071] According to one embodiment of the present application, the workpiece clamping device 100 further includes: a first gasket 70, which is disposed between the guide sleeve 33 and the adapter 50; a second gasket 80, which is disposed between the adapter 50 and the bearing bush 40, and the fixing member 61 passes through the bearing bush 40, the second gasket 80, the adapter 50 and the first gasket 70 in sequence, and is inserted into the positioning hole of the guide sleeve 33. The first gasket 70 is referred to as Figure 4 and Figure 6 The first gasket 70 is sleeved on the adapter 50 and placed between the guide sleeve 33 and the adapter 50. The second gasket 80 is shown in FIG. Figure 4 and Figure 7 The end of the adapter 50 away from the spherical protrusion 51 contacts the second gasket 80 and is placed between the adapter 50 and the bearing bush 40. The first gasket 70 and the second gasket 80 both increase the contact area and prevent loosening.
[0072] According to an embodiment of the present application, the buffer mechanism includes a plurality of buffer mechanisms, and the plurality of buffer mechanisms are arranged in the axial direction.
[0073] A buffer member 62 is sleeved on multiple fixing members 61. In some embodiments with an adapter member 50, for example, the spherical protrusion 51 causes the bearing shell 40 to tilt to one side, and the buffer member 62 cooperates with the tilt direction of the bearing shell 40. The position with a larger tilt is squeezed more by the workpiece, and the buffer member 62 is compressed shorter, while the position with a smaller tilt is squeezed less by the workpiece, and the buffer member 62 is compressed less.
[0074] According to one embodiment of the present application, the head of the fixing member 61 is flush with the surface of the bearing shell 40. The fixing member 61 passes through the bearing shell 40, the second gasket 80, the adapter 50 and the first gasket 70 in sequence. The head of the fixing member 61 can be the head of the first bolt, and its head is completely immersed in the surface of the bearing shell 40, so that when the workpiece is clamped, the bearing shell 40 is contacted instead of the fixing member 61, and the surface of the workpiece is prevented from being damaged due to excessive pressure. The second bolt 90 is similar, and the head of the second bolt 90 is completely immersed in the surface of the bearing shell 40, so that when the workpiece is clamped, the bearing shell 40 is contacted instead of the fixing member 61, and the surface of the workpiece is prevented from being damaged due to excessive pressure.
[0075] According to the inspection vehicle in the embodiment of the present application, it includes: a vehicle body and the workpiece clamping device 100 in the above embodiment. A support device is provided on the vehicle body, and the workpiece clamping device 100 is provided on the support device. When using the inspection vehicle of the present application, the staff can drive multiple adjustment mechanisms 30 at one working position, which can speed up the speed of the clamping device adapting to large workpieces and avoid repeatedly moving the working position; in addition, since the adjustment surface 301 faces the staff, it is easier to find the adjustment hole.
