Description

Technical Field

[0001] This invention relates to the field of positioning and installation technology, and in particular to a positioning tooling. Background Technology

[0002] With the rapid development of large equipment manufacturing industries such as aerospace, shipbuilding, railway, and metallurgy, it is particularly important for large equipment to have a structure that is more stable, easier to install, and more convenient to adjust.

[0003] Large equipment often suffers from significant manufacturing errors, making it difficult to control the length of support columns within a defined range. This is especially true for structures where the mounting surfaces are not on the same plane, resulting in even greater deviations between the actual and ideal mounting surfaces. This can easily lead to uneven stress distribution after installation. Uneven stress on the overall equipment can cause excessive stress on individual support points, generating a torque on the center of gravity. This can affect normal operation and damage components, shortening their lifespan. This drawback is even more pronounced in welded components. Summary of the Invention

[0004] This invention provides a positioning fixture to address one of the shortcomings of the prior art. When multiple positioning fixtures are applied to the installation and positioning of large equipment, each positioning and installation device can be adjusted individually to adapt to the height required by its installation point. Even when the installation surfaces of large equipment are not in the same plane, the positioning and support accuracy of each installation point can still be guaranteed.

[0005] This invention provides a positioning fixture, comprising:

[0006] A positioning component, wherein the positioning component is provided with a positioning area suitable for supporting a positioning installation device;

[0007] An adjustment assembly includes a base, a wedge, and a drive component. The wedge is disposed on the base and includes a first inclined surface and a connecting surface. The connecting surface is disposed above and opposite to the first inclined surface. A positioning component is disposed on the connecting surface. The base has a second inclined surface that cooperates with the first inclined surface. The drive component is connected to the wedge and is adapted to drive the wedge to move along the second inclined surface to drive the positioning component to rise and fall. The base and the positioning component are detachably connected.

[0008] According to a positioning fixture provided by the present invention, the driving component includes a first bolt and a second bolt, both of which are connected to the wedge block. The first bolt is adapted to push the wedge block from the lower end to the higher end of the second inclined surface, and the second bolt is adapted to pull the wedge block from the higher end to the lower end of the second inclined surface.

[0009] According to a positioning fixture provided by the present invention, the base is provided with a protrusion, the protrusion is located at the lower end of the second inclined surface, the protrusion is provided with a mounting groove, and the first bolt and the second bolt pass through the mounting groove and are connected to the wedge block.

[0010] According to a positioning fixture provided by the present invention, the positioning component includes a mounting plate and a positioning plate. The mounting plate has a mounting surface, the positioning plate is disposed at the edge of the mounting surface, and the positioning plate has a third inclined surface. The third inclined surface and the mounting surface limit the positioning area, and the third inclined surface is inclined from bottom to top toward the outside of the mounting plate.

[0011] According to a positioning fixture provided by the present invention, the positioning plate is rotatably connected to the mounting plate.

[0012] According to a positioning fixture provided by the present invention, the positioning component further includes a limiting block, the limiting block being disposed on the mounting surface and being disposed opposite to the positioning plate.

[0013] According to a positioning fixture provided by the present invention, the limiting block is detachably connected to the mounting plate.

[0014] According to a positioning fixture provided by the present invention, the positioning component further includes a support column, the support column is vertically arranged, the upper end of the support column is connected to the mounting plate, the lower end face is provided with a first through hole, and the protrusion is provided with a second through hole communicating with the first through hole. The first through hole and the second through hole can be fixed by fasteners.

[0015] According to a positioning fixture provided by the present invention, the lower end of the support column is provided with a fixing frame, the bottom surface of the fixing frame is provided with the first through hole, and the fixing frame is provided with an installation cavity at the position corresponding to the first through hole.

[0016] According to a positioning fixture provided by the present invention, the positioning component further includes an adjustment part disposed on the mounting plate, the adjustment part being adapted to adjust the distance between the mounting device and the mounting surface.

[0017] The positioning fixture provided by this invention has a positioning component whose positioning area corresponds to the installation point below the installation equipment, awaiting the installation equipment to be positioned. The height of the positioning component is adjusted by an adjusting component. A wedge block of the adjusting component is mounted on a base, with its first inclined surface contacting the second inclined surface of the base. Driven by a driving component, the wedge block can move along the second inclined surface. The connecting surface on the wedge block is opposite to the first inclined surface and is located above the first inclined surface. From bottom to top, the components are the second inclined surface, the first inclined surface, and the connecting surface. When the wedge block moves from the lower end to the higher end of the second inclined surface, the positioning component rises synchronously. When the wedge block moves from the higher end to the lower end of the second inclined surface, the positioning component descends synchronously until the height of the positioning area of ​​the positioning component meets the installation requirements of the installation equipment. Then, the hoisted installation equipment slowly descends until it is positioned within the positioning area of ​​the positioning component. The adjusting component and the positioning component work together to complete the coarse positioning of the installation equipment.

[0018] Because the height of the positioning component is adjusted before the equipment is placed, the adjustment component is easy to operate and the adjustment structure is relatively simple. During the movement of the wedge, the base and the positioning component can be initially disconnected. After the wedge has moved and its position is determined, the positioning component is then connected to the base and fixed in place. This ensures that the positioning component will not shift with the horizontal movement of the wedge, but will only change in vertical height. This ensures that the horizontal position of the positioning component remains unchanged, and only the height of the installed equipment is adjusted vertically. Consequently, the positioning area will not shift from the determined installation point, guaranteeing the accuracy of the equipment positioning and improving the positioning precision of the installed equipment.

[0019] When multiple positioning fixtures are used for the installation and positioning of large equipment, each positioning and installation device can be adjusted individually to adapt to the height required by its installation point. Even if the installation surfaces of large equipment are not on the same plane, the positioning support accuracy of each installation point can be guaranteed, reducing the deviation between the actual installation surface and the ideal installation surface, so that the overall force on the equipment is uniform after installation and it is not easy to affect normal use.

[0020] Choose appropriate installation points and utilize the different directions of the multi-point support positioning plate to fully constrain the degrees of freedom of the installed equipment. For equipment prone to misidentification of its orientation, a slope with the same angle as the positioning plate can be machined onto the mounting surface to prevent incorrect installation. Use wedges to adjust the height of the positioning components to ensure full contact between the mounting surface and the installed parts, and uniform force distribution at each support point. In the case of one main support and multiple auxiliary supports, the degrees of freedom can be fully constrained by the main support point, and the remaining support points only need to have their height adjusted to ensure full engagement of the mounting surface.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] like Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a positioning fixture, including a positioning component 100 and an adjustment component 200. The positioning component 100 is provided with a positioning area suitable for supporting a positioning installation device. The adjustment component 200 includes a base 210, a wedge 220 and a driving component 230. The wedge 220 is disposed on the base 210 and includes a first inclined surface 221 and a connecting surface 222. The connecting surface 222 is disposed above the first inclined surface 221 and opposite to the first inclined surface 221. The positioning component 100 is disposed on the connecting surface 222. The base 210 is provided with a second inclined surface 211 that cooperates with the first inclined surface 221. The driving component 230 is connected to the wedge 220 and is suitable for driving the wedge 220 to move along the second inclined surface 211 to drive the positioning component 100 to rise and fall. The base 210 and the positioning component 100 are detachably connected.

[0029] In this embodiment of the invention, the positioning fixture has a positioning area of ​​the positioning component 100 corresponding to the installation point below the installation equipment, awaiting the installation equipment to be positioned. The height of the positioning component 100 is adjusted by the adjusting component 200. The wedge 220 of the adjusting component 200 is set on the base 210. The first inclined surface 221 of the wedge 220 contacts the second inclined surface 211 of the base 210, and under the drive of the driving component 230, the wedge 220 can move along the second inclined surface 211. The connecting surface 222 on the wedge 220 is positioned opposite to the first inclined surface 221. The wedge 220 is positioned above the first inclined surface 221, i.e., from bottom to top, the components are the second inclined surface 211, the first inclined surface 221, and the connecting surface 222. When the wedge 220 moves from the lower end to the higher end of the second inclined surface 211, the positioning component 100 rises synchronously as the wedge 220 rises. When the wedge 220 moves from the higher end to the lower end of the second inclined surface 211, the positioning component 100 falls synchronously as the wedge 220 falls, until the positioning area of ​​the positioning component 100 meets the installation requirements of the installation equipment. Then, the hoisted installation equipment slowly descends until it is positioned in the positioning area of ​​the positioning component 100. The adjusting component 200 cooperates with the positioning component 100 to complete the coarse positioning of the installation equipment.

[0030] Since the height of the positioning component 100 is adjusted before the equipment is placed in position, the adjustment component 200 is easy to operate and the adjustment structure is relatively simple. During the movement of the wedge block 220, the base 210 and the positioning component 100 can be disconnected initially. After the wedge block 220 has moved and its position is determined, the positioning component 100 is then connected to the base 210 to fix its position. This ensures that the positioning component 100 will not shift with the horizontal movement of the wedge block 220, but will only change in vertical height. This ensures that the horizontal position of the positioning component 100 does not change, and only the vertical height of the equipment is adjusted. Consequently, the positioning area will not shift from the determined installation point, ensuring the accuracy of the equipment positioning and improving the positioning precision of the equipment.

[0031] When multiple positioning fixtures are used for the installation and positioning of large equipment, each positioning and installation device can be adjusted individually to adapt to the height required by its installation point. Even though the installation surfaces 111 of the large equipment are not in the same plane, the positioning support accuracy of each installation point can be guaranteed, reducing the deviation of the actual installation surface 111 from the ideal installation surface 111, so that the overall force of the equipment is uniform after installation and it is not easy to affect normal use.

[0032] By selecting appropriate installation points and utilizing the different directions of the multi-point support positioning plate 120, the degrees of freedom of the installed equipment can be fully constrained. For installations where orientation is easily misidentified, a slope with the same angle as the positioning plate 120 can be machined onto the mounting surface 111 to prevent incorrect installation. The height of the positioning component 100 is adjusted using wedges 220 to ensure full contact between the mounting surface 111 and the installed component, and uniform force distribution at each support point. In the case of one main support and multiple auxiliary supports, the degrees of freedom can be fully constrained by the main support point, while the remaining support points only need to have their height adjusted to ensure full engagement with the mounting surface 111.

[0033] In this embodiment, the inclination angle of the first inclined surface 221 of the wedge 220 is selected after the material friction coefficient is calculated, so that the wedge 220 can be self-locked on the base 210 by the friction between the first inclined surface 221 and the second inclined surface 211, so as to avoid loosening after the wedge 220 moves into place.

[0034] According to one embodiment of the present invention, the driving member 230 includes a first bolt 231 and a second bolt 232. Both the first bolt 231 and the second bolt 232 are connected to the wedge block 220. The first bolt 231 is adapted to push the wedge block 220 from the lower end to the higher end of the second inclined surface 211, and the second bolt 232 is adapted to pull the wedge block 220 from the higher end to the lower end of the second inclined surface 211.

[0035] In this embodiment, the movement and adjustment of the wedge block 220 can be achieved by bidirectional pushing and pulling using the first bolt 231 and the second bolt 232. By pushing the first bolt 231 to apply force to the wedge block 220, the first bolt 231 pushes the wedge block 220 upward along the second inclined surface 211 of the base 210, causing the wedge block 220 to rise. By pulling the second bolt 232 to apply force to the wedge block 220, the second bolt 232 pulls the wedge block 220 downward along the second inclined surface 211 of the base 210, causing the wedge block 220 to descend. The operator can operate manually, and the dragging action makes the adjustment of the wedge block 220 more convenient.

[0036] In this embodiment, both the first bolt 231 and the second bolt 232 are detachably connected to the wedge block 220. When the first bolt 231 pushes the wedge block 220 upward, in order to avoid interference from the second bolt 232, the second bolt 232 can be removed from the wedge block 220 or unscrewed out of the wedge block 220 by a certain length to meet the movement requirements of the first bolt 231 and the wedge block 220. Similarly, when the second bolt 232 pulls the wedge block 220 downward, in order to avoid interference from the first bolt 231, the first bolt 231 can be removed from the wedge block 220 or unscrewed out of the wedge block 220 by a certain length to meet the movement requirements of the second bolt 232 and the wedge block 220.

[0037] In this embodiment, there are two first bolts 231 and one second bolt 232. The two first bolts 231 are located on both sides of the second bolt 232. The first bolts 231 and the second bolt 232 act on the same horizontal position on the wedge block 220 and are evenly distributed to ensure that the wedge block 220 is subjected to a balanced thrust and a balanced pull.

[0038] In other embodiments, the drive component 230 may also include a device structure such as a piston cylinder capable of pushing and pulling. For example, a bolt and nut in the vertical direction are used to fix the bolt, and the lifting and lowering are achieved by adjusting the height of the nut. A reasonable structure needs to be selected based on factors such as the actual force at each installation point.

[0039] According to one embodiment of the present invention, the base 210 is provided with a protrusion 212, which is located at the lower end of the second inclined surface 211. The protrusion 212 is provided with a mounting groove 213, through which a first bolt 231 and a second bolt 232 pass and connect with a wedge block 220. In this embodiment, the base 210 is provided with a protrusion 212 at the lower end of the second inclined surface 211, and a mounting groove 213 is provided on the protrusion 212 corresponding to the first bolt 231 and the second bolt 232. The mounting groove 213 is a through groove that passes through the protrusion 212, and both the first bolt 231 and the second bolt 232 can pass through the mounting groove 213 and connect with the wedge block 220.

[0040] The mounting groove 213 has a certain depth in the vertical direction. When the wedge block 220 is pushed or pulled to rise or fall, the height position of the wedge block 220 in the vertical direction changes. At the same time, the first bolt 231 and the second bolt 232, which are connected to the wedge block 220, also rise and fall synchronously with the wedge block 220, and their height positions in the vertical direction change. In order to ensure that the movement of the first bolt 231 and the second bolt 232 is not obstructed, the mounting groove 213 is provided. It can provide guidance for the horizontal movement of the first bolt 231 and the second bolt 232, and also allow the first bolt 231 and the second bolt 232 to have space to move in the vertical direction.

[0041] Understandably, the minimum force required to move the wedge 220 is calculated based on the weight of the positioning component 100 and the coefficient of friction between the wedge 220 and the contact surface of the positioning component 100, thereby selecting the appropriate size of the first bolt 231 and the second bolt 232. When the wedge 220 is at the lower end of the second inclined plane 211, the connecting surface 222 of the wedge 220 is flush with the upper surface of the protrusion 212. As the wedge 220 moves towards the upper end of the second inclined plane 211, the connecting surface 222 gradually rises above the upper surface of the protrusion 212.

[0042] According to an embodiment of the present invention, the positioning component 100 includes a mounting plate 110 and a positioning plate 120. The mounting plate 110 is provided with a mounting surface 111, and the positioning plate 120 is disposed at the edge of the mounting surface 111. The positioning plate 120 is provided with a third inclined surface 121, which, together with the mounting surface 111, defines a positioning area. The third inclined surface 121 is inclined from bottom to top toward the outside of the mounting plate 110.

[0043] In this embodiment, the mounting plate 110 is horizontally positioned, with its upper surface being the mounting surface 111. The bottom surface of the positioning plate 120 is located at the edge of the mounting surface 111, and the third inclined surface 121 of the positioning plate 120 faces the side where the mounting surface 111 is located. The hoisted installation equipment gradually descends into the positioning area formed by the mounting surface 111 and the third inclined surface 121. As it approaches the mounting surface 111, the edge of the installation equipment first contacts the third inclined surface 121 of the positioning plate 120. As the installation equipment continues to descend, the edge of the installation equipment remains in contact with the third inclined surface 121. The third inclined surface 121 acts as a support, ensuring that the installation equipment is stably positioned on the mounting surface 111. The third inclined surface 121 gradually slopes upwards from the bottom surface of the positioning plate 120 towards the outside of the mounting plate 110. The positioning plate 120 serves as a coarse positioning structure for the installation equipment during installation, and the third inclined surface 121 causes the installation equipment to fall along a fixed trajectory.

[0044] In the existing technology, due to the heavy weight of the large installation equipment itself, it is not easy to control the position during the installation process. Since the crane's lifting ropes are flexible rather than rigid, the swaying of the lifting ropes can easily cause bumps and knocks on the installation surface 111 or other locations. Minor issues may require on-site repairs, while major issues may require returning the equipment to the factory for repair, resulting in a waste of time, manpower, material resources, and financial resources. Moreover, it is difficult to accurately align the position of the mounting holes on the installation surface 111, which often requires manual adjustment, which is both laborious and difficult to adjust accurately.

[0045] The equipment installed in this application is lowered along the third inclined plane 121, which can effectively stabilize the hoisting of the equipment, prevent swaying and swinging, and ensure more precise positioning. Utilizing the third inclined plane 121 for coarse positioning results in a simple and easy-to-implement structure, allowing for convenient and quick adjustment of the equipment's position, saving manpower and resources.

[0046] In this embodiment, a tapered pin or other available form can be used for coarse positioning. The most economical, effective, reliable and reasonable structure should be selected based on the actual structural form of the equipment, space constraints and other specific requirements.

[0047] According to one embodiment of the present invention, the positioning plate 120 is rotatably connected to the mounting plate 110. In this embodiment, the positioning plate 120 can be rotatably mounted on the mounting plate 110, and one end of the bottom of the positioning plate 120 is rotatably connected to the mounting plate 110. With this connection position as the axis, the positioning plate 120 can be located at the other edge of the mounting plate 110, that is, the positioning plate 120 can be rotated from a horizontal lateral limit to a horizontal longitudinal limit.

[0048] In this embodiment, before the installation equipment is placed in position, the positioning plate 120 rotates on the mounting surface 111 to the limiting direction required by the installation point, that is, changes the orientation of the third inclined surface 121 to adapt to the positioning required by the installation point. When the positioning fixture of the present invention is used in conjunction with multiple installation points, the device is used in groups, the support position is reasonably selected, and the direction of the third inclined surface 121 is adjusted to achieve bidirectional positioning.

[0049] According to one embodiment of the present invention, the positioning component 100 further includes a limiting block 130, which is disposed on the mounting surface 111 and is disposed opposite to the positioning plate 120. In this embodiment, the positioning plate 120 and the limiting block 130 are respectively disposed on the opposite two edges of the mounting surface 111, that is, the limiting block 130 is also within the positioning area. After coarse positioning by the positioning plate 120, the position of the mounting component is restricted by the limiting block 130 for precise positioning.

[0050] After the installation equipment is placed on the mounting surface 111, it can abut against the side of the limiting block 130 facing the positioning plate 120. Thus, the limiting block 130 can prevent the installation equipment from sliding out from the side of the mounting surface 111 opposite to the positioning plate 120, and play a limiting and fixing role for the installation equipment.

[0051] In this embodiment, the limiting block 130 is a rectangular strip with the same length as the positioning plate 120, and extends along the edge of the mounting plate 110.

[0052] According to one embodiment of the present invention, the limiting block 130 is detachably connected to the mounting plate 110. In this embodiment, the actual distance between the limiting block 130 and the positioning plate 120 is set according to the actual installation needs. The limiting block 130 is detachably mounted on the mounting plate 110. If the assembly error of the installation equipment in the positioning area is large, the interfering limiting block 130 can be removed to increase the range involved in the positioning area, thereby adjusting the placement of the installation equipment to reduce the assembly error.

[0053] In this embodiment, the limiting block 130 can be connected to the mounting plate 110 by bolts, and the mounting plate 110 has connecting holes for bolt connection at corresponding positions. In other embodiments, the position of the limiting block 130 on the mounting plate 110 is adjustable, such as the vertical distance from the positioning plate 120 being variable. That is, multiple connecting hole positions are provided in the direction of the vertical distance between the mounting plate 110 and the positioning plate 120, and the limiting block 130 can be adjusted on the mounting plate 110 by fixing bolts to different mounting holes.

[0054] According to an embodiment of the present invention, the positioning component 100 further includes a support column 140, which is vertically arranged. The upper end of the support column 140 is connected to the mounting plate 110, and the lower end face is provided with a first through hole 141. The protrusion 212 is provided with a second through hole 214 communicating with the first through hole 141. The first through hole 141 and the second through hole 214 can be fixed by fasteners.

[0055] In this embodiment, the upper end of the support column 140 is a mounting plate 110, and the lower end of the support column 140 is connected to the protrusion 212 of the base 210 while contacting the connecting surface 222 of the wedge block 220. The wedge block 220 is placed at the lower end of the support column 140. After the wedge block 220 is moved and adjusted, the lower end of the support column 140 is placed on the connecting surface 222 of the wedge block 220. At the same time, a first through hole 141 is provided on the lower end surface, and a second through hole 214 is correspondingly provided on the protrusion 212. The first through hole 141 and the second through hole 214 are then connected by fasteners, thereby realizing the connection and fixation between the support column 140 and the base 210. That is, the wedge block 220 is clamped and fixed between the base 210 and the support column 140, which can also play a role in fixing the wedge block 220.

[0056] In one embodiment, the installation device requires four installation points. Four evenly distributed positioning fixtures are selected. The size, height, and installation method of the positioning plates 120 and limiting blocks 130 are determined by the actual installation space of the device. Two of the positioning plates 120 have their third inclined surfaces 121 facing forward, while the third inclined surfaces 121 of the other two positioning plates 120 face to the side, with the diagonal directions being the same. This ensures that the installation device's degrees of freedom in the horizontal plane are fully constrained. The diagonal positioning plates 120 also maintain stability during descent, preventing significant displacement.

[0057] When the wedge 220 is at the lower end of the second inclined surface 211, the mounting surface 111 is a certain distance from the theoretical mounting surface. This ensures that the mounting surface 111 can reach the theoretical mounting surface height by adjusting the height of the wedge 220. The height of the support column 140 is a fixed value. The adjustment component 200 can effectively prevent the height of the support column 140 from exceeding the theoretical mounting position and becoming unadjustable.

[0058] In this embodiment, the fastener can be a bolt.

[0059] According to an embodiment of the present invention, the lower end of the support column 140 is provided with a fixing frame 142, the bottom surface of the fixing frame 142 is provided with a first through hole 141, and the fixing frame 142 is provided with an installation cavity 143 at the position corresponding to the first through hole 141. In this embodiment, the lower end of the support column 140 is designed as a frame, the top surface of the fixing frame 142 is connected to the bottom surface of the support column 140, the bottom surface of the fixing frame 142 is provided with a first through hole 141, and an installation cavity 143 is constructed at the position of the first through hole 141. When the wedge block 220 has moved and it is necessary to connect and fix the support column 140 to the protrusion 212 of the base 210, the installation cavity 143 provides space for workers to manually install fasteners. That is, the installation cavity 143 is a reserved working space for the installation of the support column 140 and the base 210.

[0060] In this embodiment, the first through holes 141 are divided into two groups, with two first through holes 141 in each group. The fixing frame 142 encloses two mounting cavities 143 corresponding to the two groups of first through holes 141 respectively. Similarly, the second through holes 214 are arranged in a one-to-one correspondence with the first through holes 141, and are also divided into two groups. One group is between the mounting groove 213 where the first bolt 231 is located and the mounting groove 213 where the second bolt 232 is located, and the other group is between the mounting groove 213 where the first bolt 231 is located and the mounting groove 213 where the second bolt 232 is located.

[0061] According to one embodiment of the present invention, the positioning component 100 further includes an adjustment section disposed on the mounting plate 110. The adjustment section is adapted to adjust the distance between the mounting device and the mounting surface 111. In this embodiment, the mounting plate 110 where the limiting block 130 is located can be threaded with a hole as needed, and the mounting surface 111 where the mounting device is to be positioned can be finely adjusted using screws. Alternatively, space can be reserved for fine-tuning using a jack. Other adjustment structures can also be provided to adjust the support and position of the mounting component, such as a spherical support with a cylinder, where the spherical support restricts the degree of freedom and the cylinder prevents over-positioning. By providing the adjustment section, a certain degree of fine positioning can be further achieved after the coarse positioning of the positioning plate 120 and the adjustment component 200.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
