Detailed Implementation
[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] The embodiment of this application is as follows:
[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of the inspection tooling and welding fixture of this utility model. Figure 2 This is a schematic diagram of the insertion hole 102 and the pin rod of this utility model. Figure 3 This is a structural schematic diagram of the limiting component of this utility model. Figure 4 This is a schematic diagram of the structure of the mating block 110 and the mating cap 111 of this utility model.
[0021] This utility model discloses a welding fixture for inspection tools, comprising a base plate 101, an insertion hole 102, a pin post 103, a mounting block 104, a connecting post 105, a rotating seat 106, a contact head 107, a threaded rod 108, a top block 109, a mating block 110, a mating cap 111, a groove 112, a protrusion 113, a sliding post 114, a top cap 115, a spring 116, and a handle 117. It solves the problem that most inspection tools are irregularly shaped, while existing fixtures are mostly limited to clamping specific workpieces, resulting in poor versatility and difficulty in fixing inspection tools of different specifications. It is understood that the aforementioned solution can also be used to improve adaptability.
[0022] In this embodiment, the base plate 101 is a rectangular plate, and the number of insertion holes 102 penetrating the base plate 101 is several, evenly arranged on the base plate 101. The through-holes 102 facilitate cleaning. The number of fixing components is multiple sets. By installing multiple sets of fixing components on the base, the problem of poor versatility and difficulty in fixing different specifications of fixtures is solved, since most of the inspection fixtures are irregularly shaped and most of the existing clamps can only clamp specific workpieces.
[0023] The pin 103 is detachably connected to the base plate 101 via the insertion hole 102. The mounting block 104 is fixedly connected to the pin 103 and located at the top of the pin 103. The connecting post 105 is fixedly connected to the mounting block 104 and located on the side of the mounting block 104 away from the pin 103. The rotating seat 106 is sleeved on the outside of the connecting post 105 and rotatably connected to the connecting post 105. The contact head 107 is detachably connected to the rotating seat 106 and located on one side of the rotating seat 106. The limiting member is installed on the rotating seat 106. The pin 103 is a cross-shaped column, and the outline of the insertion hole 102 matches the pin 103. The pin 103 is inserted into the insertion hole 102, and can be inserted into any one of the insertion holes 102. Its position can be adjusted as needed, and it is easy to assemble and disassemble. The mounting block 104 is circular and is fixedly installed on the top of the pin 103. The connecting column 105 is a cylinder and is vertically installed on the top of the mounting block 104. The rotating seat 106 has a through hole that matches the connecting column 105, and the rotating seat 106 is sleeved on the outside of the connecting column 105 through the through hole. The rotating base 106 can rotate freely around the connecting column 105. Two threaded holes are provided on one side of the rotating base 106. The contact head 107 is detachably connected to the rotating base 106 by bolts. The contact head 107 is mounted on one side of the rotating base 106, forming an eccentric body that can rotate around the connecting column 105. When clamping a workpiece, rotating the rotating base 106 causes the contact head 107 to contact the workpiece, thereby limiting and fixing the workpiece. The contact head 107 is designed as a detachable structure, allowing it to be adjusted according to different workpiece requirements. The replacement mechanism improves convenience. The limiting component is installed on the rotating seat 106 to limit the rotation seat 106, so that the contact head 107 can be kept in a fixed position, preventing the contact head 107 from shifting and improving the stability of workpiece clamping. By designing the pin post 103 as a structure that can be moved easily, and cooperating with the rotation adjustment of the contact head 107, it is easy to clamp different workpieces, greatly improving adaptability. This solves the problem that most inspection fixtures are irregularly shaped, and most existing fixtures can only clamp specific workpieces, resulting in poor versatility and difficulty in fixing inspection fixtures of different specifications.
[0024] Secondly, the threaded rod 108 passes through the rotating seat 106 and is threadedly connected to the rotating seat 106; the top block 109 is fixedly connected to the threaded rod 108 and is located at the top end of the threaded rod 108; the mating block 110 is fixedly connected to the top block 109 and is located on the side of the top block 109 away from the threaded rod 108; the mating cap 111 is connected to the top block 109 through the support member, the support member is installed on the top block 109 and supports the mating cap 111, the mating cap 111 mates with the mating block 110, the rotating seat 106 has a threaded through hole, the threaded rod 108 passes through the threaded through hole and is threadedly connected to the rotating seat 106, the top block 109 is circular and is fixedly installed at the top end of the threaded rod 108, the mating block 110 is fixedly installed on the top of the top block 109, and the mating cap 111 is connected to the top block 109 through the support member. The support member is installed on the top block 109. The mating cap 111 can mate with the mating block 110. The support member can provide elastic support for the mating cap 111, facilitating the mating cap 111 and the mating block 110 to mate and separate. When the mating cap 111 and the mating block 110 are mated together, rotating the mating cap 111 can drive the mating block 110 and the threaded rod 108 to rotate. The bottom end of the threaded rod 108 abuts against the mounting block 104. Under the action of friction, the rotating seat 106 can be limited, thus achieving the limitation and fixation of the rotating seat 106. When the mating cap 111 is not mated with the mating block 110, the rotation of the mating cap 111 cannot drive the threaded rod 108 to rotate. By the bottom end of the threaded rod 108 abutting against the mounting block 104, the rotating seat 106 can be limited and fixed.
[0025] Meanwhile, the mating block 110 has a groove 112 located on the outer periphery of the mating block 110; the mating cap 111 has a protrusion 113 that engages with the groove 112. There are multiple grooves 112, which are evenly distributed on the outer periphery of the mating block 110. The protrusion 113 is located on the inner wall of the mating cap 111 and can be inserted into the groove 112. Through the protrusion 113 and the groove 112, the mating cap 111 and the mating block 110 are engaged.
[0026] In addition, the sliding post 114 is fixedly connected to the mating block 110 and slidably connected to the mating cap 111; the top cap 115 is threadedly connected to the sliding post 114 and located at the end of the sliding post 114 away from the mating block 110; the spring 116 is disposed between the top block 109 and the mating cap 111; the sliding post 114 is vertically installed on the top of the mating block 110; the mating cap 111 has a through hole in the middle that matches the sliding post 114; the mating cap 115... 11 is sleeved on the outside of the sliding post 114 through the through hole. The top of the sliding post 114 is provided with an external thread, and the top cap 115 has an internal thread. Through the internal thread and the external thread, the top cap 115 is threadedly connected to the sliding post 114 to limit the mating cap 111. The spring 116 is in a compressed state, and its two ends are in contact with the top block 109 and the mating cap 111 respectively. Through the elastic force of the spring 116, the mating cap 111 is elastically supported.
[0027] Finally, the handle 117 is fixedly connected to the mating cap 111 and is located on the outer periphery of the mating cap 111. The handle 117 facilitates the rotation of the mating cap 111. Under the support of the spring 116, the mating cap 111 and the mating block 110 remain in a non-mating state for a long time. Pressing the handle 117 causes the mating cap 111 to move downward, so that the mating cap 111 can engage with the mating block 110 and control the rotation of the threaded rod 108. The handle 117 facilitates the rotation of the mating cap 111.
[0028] In this embodiment, when clamping the welding fixture, multiple sets of fixing components are selected and installed on the base plate 101. These fixing components are arranged around the outside of the welding fixture. When installing the fixing components, simply insert the pin 103 into the insertion hole 102. After the fixing components are installed, the fixture is placed on the base plate 101 and positioned between the fixing components. Then, the contact heads 107 on each fixing component are adjusted so that they abut against the fixture at different positions. When adjusting the contact heads 107, the rotating seat 106 is rotated to rotate the contact heads 107 until they abut against the fixture. Then, the handle 117 is pressed, causing the mating cap 111 to move downwards. During this process, the handle 117 can be rotated so that the protrusion 113 can engage with the groove 112, allowing the mating cap 111 to move downwards. The 111 can be engaged with the mating block 110. After the mating cap 111 and the mating block 110 are engaged, the handle 117 is turned clockwise. Under the engagement of the mating cap 111 and the mating block 110, the threaded rod 108 is driven to rotate. The threaded rod 108 is threadedly connected to the rotating seat 106. During the rotation, the threaded rod 108 moves downward until its end abuts against the mounting block 104. Under the action of friction, the rotating seat 106 is limited and fixed, thereby fixing the position of the contact head 107. After multiple contact heads 107 contact the gauge from different directions, the gauge can be fixed. After the handle 117 is released, under the action of the spring 116, the handle 117 will move upward. At this time, the mating cap 111 and the mating block 110 can respectively rotate the handle 117 freely to adjust its position so as not to affect the welding work. This application can be flexibly adjusted according to the specifications of the gauge. By abutting the gauge with multiple abutting blocks in different directions, the gauge can be clamped and fixed. It has strong adaptability and solves the problem that most gauges are irregularly shaped and existing fixtures can only clamp specific workpieces, resulting in poor versatility and difficulty in fixing gauges of different specifications.
