Description

A tungsten sheet assembly device for an tilt sensor Technical Field

[0001] This utility model relates to the field of tilt sensor manufacturing, and in particular to a tungsten sheet assembly device for tilt sensors. Background Technology

[0002] For redundant single-axis digital tilt sensors, since they are used in medical equipment (such as CT scanners), there will be certain radiation and interference to the tilt sensor. In order to avoid radiation or interference to the tilt sensor during the operation of the whole equipment and cause distortion of its data signal, tungsten sheets need to be installed on the side and top of the tilt sensor housing.

[0003] The tungsten sheet on the side needs to be fixed to the outer side of the sensor housing with screws. Because the side wall thickness of the housing is relatively small (approximately 1mm), directly machining threaded holes in the housing reduces the number of threads that engage with the screw, making it very easy for the screw to strip during tightening, thus preventing the tungsten sheet from being securely fixed. Therefore, a combination of screws and nuts is currently used to fix the tungsten sheet to the sensor housing. However, during the tungsten sheet assembly process, the operator needs to hold the screw tightening tool in one hand and the nut fixing tool in the other, making it difficult to secure the sensor housing. This results in ineffective alignment of the tungsten sheet during assembly, causing misalignment between the edges of the tungsten sheet and the bottom mounting surface of the housing after it is actually fixed, with the lower edge of the tungsten sheet extending beyond the bottom surface of the housing. The inability to position the tungsten sheet during tightening and the inability to secure the housing ultimately lead to the lower edge of the tungsten sheet extending beyond the bottom surface of the housing. Furthermore, when the tilt sensor reaches the debugging stage after assembly, it cannot be placed flat on the debugging fixture, thus affecting the normal progress of the debugging process and reducing production efficiency. Summary of the Invention

[0004] To address the technical problems in the background art, this utility model provides a tungsten sheet assembly device for an angle sensor. The device includes a tooling base plate placed horizontally on a workbench, a product fixing seat and a clamping assembly respectively disposed on the tooling base plate. The product fixing seat has a positioning groove for positioning and placing the angle sensor housing to be assembled and a positioning groove for the tungsten sheet. The clamping assembly is disposed opposite to the other side of the tungsten sheet of the angle sensor assembly to clamp the angle sensor housing.

[0005] Furthermore, the positioning groove of the tilt sensor housing and the positioning groove of the tungsten sheet are formed in the space between the bottom panel, the back panel and the two side panels of the product mounting base.

[0006] Furthermore, the width of the positioning groove of the tilt sensor housing is greater than the length of the tilt sensor housing to be assembled, and after the tilt sensor to be assembled is installed and positioned in the positioning groove of the tilt sensor housing, a gap of 0.2~0.3mm is reserved on both sides respectively.

[0007] Furthermore, the positioning groove of the tungsten sheet is formed inside the back panel of the product fixing base, and the bottom surface of the positioning groove of the tungsten sheet is higher than the upper surface of the bottom panel to ensure that the tungsten sheet will not protrude from the bottom of the tilt sensor housing after locking.

[0008] Furthermore, the width of the positioning groove of the tungsten sheet is greater than the length of the tungsten sheet, and after the tungsten sheet is inserted into the positioning groove of the tungsten sheet, a gap of 0.2~0.3mm is reserved on both sides respectively.

[0009] Furthermore, the clamping assembly includes a clamping pad fixed to the tooling base plate and a horizontal elbow clamp fixed to the clamping pad, the horizontal elbow clamp being disposed opposite to the other side of the tilt sensor mounting tungsten sheet.

[0010] Furthermore, the front end of the horizontal elbow clamp is provided with an adjustable protrusion length rubber-head screw and a nut for locking the rubber-head screw.

[0011] Furthermore, the bottom panel of the product mounting base is fixed to the tooling base plate by the first fixing screw.

[0012] Furthermore, an L-shaped notch is provided on each of the two side panels of the product mounting base to avoid the connector and cable on the tilt sensor housing, and a U-shaped notch is provided on the back panel of the product mounting base to avoid the fixing screws of the tungsten sheet.

[0013] Furthermore, the tooling base plate is placed on the workbench via horizontal support feet at its four corners.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention solves the problems of positioning the tungsten sheet and fixing the tilt sensor housing during assembly. Positioning surface A and a horizontal elbow clamp limit and maintain its position, resolving the issue of the housing failing to be fixed during tungsten sheet locking. The product mounting base has a height difference H2 between its two positioning surfaces A and B, preventing the tungsten sheet from protruding from the outer bottom surface of the housing due to misalignment during locking, which would hinder subsequent debugging processes. This device is highly reliable, highly operable, and can be adapted to other tilt sensor models by replacing the mounting base with other specifications, demonstrating strong expandability.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Example

[0029] This invention provides a tungsten sheet assembly device for a tilt sensor, which assists in the installation process of the tungsten sheet during the manufacturing of the tilt sensor. As shown in Figure 1, the tungsten sheet assembly device includes a tooling base plate 1, a product fixing seat 2, a horizontal support leg 3, a clamping pad 4, and a horizontal elbow clamp 5.

[0030] Each of the four corners of the fixture base plate 1 has a through hole for installing a horizontal support leg 3, so that the entire device can be placed horizontally and stably on the workbench. Two first threaded holes are opened on the left side of the fixture base plate 1 to be used with two first fixing screws 6 to fix the product fixing seat 2 on the fixture base plate 1. Four second threaded holes are opened on the right side of the center of the fixture base plate. The horizontal elbow clamp 5 and the clamping pad 4 are fixed to the fixture base plate 1 together by four second fixing screws 7. The clamping pad 4 is set below the horizontal elbow clamp 5 to adjust the height of the horizontal elbow clamp 5.

[0031] As shown in Figure 2, the product mounting base 2 is a metal part with a groove. The groove includes positioning slots for placing and positioning the tilt sensor housing 8 to be installed and the tungsten sheet. The product mounting base 2 consists of a bottom panel, a back panel, and two side panels. The width of the positioning slot of the tilt sensor housing 8 is slightly larger than the length of the tilt sensor housing 8, and a gap of 0.2~0.3mm is reserved on each side so that the tilt sensor housing 8 can be smoothly placed in the positioning slot of the tilt sensor housing 8. In addition, the positioning slot of the tungsten sheet is set between the positioning slot of the tilt sensor housing 8 and the back panel. After the tilt sensor housing 8 is fixedly installed, the tungsten sheet is inserted into the positioning slot of the tungsten sheet from top to bottom.

[0032] In Figure (2b), an L-shaped notch is provided on each of the left and right side panels of the product fixing base 2 to avoid the connector and cable on the tilt sensor housing 8. A positioning surface A (the side of the positioning groove of the tilt sensor housing 8) is provided on the inner side of the left and right side panels, and a positioning surface B (the back of the positioning groove of the tungsten sheet) is provided on the inner side of the back panel. The positioning surface A is used as the left and right limit of the tilt sensor housing 8, and the positioning surface B is used as the limit of the tungsten sheet. The horizontal distance H1 between the inner side of the positioning surface A and the surface where the positioning surface B is located is 1.2mm. In Figure (2d), the vertical distance H2 between the bottom edge of the positioning surface A and the bottom edge of the positioning surface B is 0.5mm. The bottom of the positioning surface B is higher than the bottom of the positioning surface A to ensure that the tungsten sheet will not protrude from the bottom of the tilt sensor housing 8 after locking.

[0033] In Figure (2c), two cylindrical countersunk holes are provided on the bottom panel of the product mounting base 2. The depth of the countersunk holes is greater than the thickness of the cylindrical head of the first fixing screw 6, so as to ensure that the head of the first fixing screw 6 will not protrude from the bottom panel of the product mounting base 2 after it is fixed. In Figure (2a), a U-shaped notch is provided on the back panel of the product mounting base 2 to avoid the tungsten sheet fixing screw 10, so as to facilitate installation and tightening. The width of the positioning surface B is greater than the length of the tungsten sheet, and a gap of 0.2~0.3mm is reserved on both sides so that the tungsten sheet can be smoothly placed between the positioning surface B and the side of the tilt sensor housing 8.

[0034] As shown in Figure 3, the front end of the horizontal elbow clamp 5 is provided with a rubber head screw C, and the rubber head screw C can adjust its extension length H3, thereby adjusting the clamping force of the horizontal elbow clamp 5 on the side of the tilt sensor; the nut D is used to lock the adjusted rubber head screw C to prevent it from loosening during use.

[0035] In another feasible embodiment, the rubber-headed screw C can be replaced with a U-shaped push rod whose tail end is telescopically adjustable to the front end of the horizontal elbow clamp 5. The bottom surface of the U-shaped head of the U-shaped push rod fits against the side of the tilt sensor, and the two sides clamp the tilt sensor to increase stability and prevent loosening during the installation of the tungsten sheet.

[0036] As shown in Figure 4, the tungsten sheet assembly device is used as follows:

[0037] 1) First, place the tilt sensor housing 8 with the tungsten sheet to be installed on the product fixing base 2 and push it to the positioning surface A. Adjust the position of the rubber head screw C on the horizontal elbow clamp 5 so that it can just press the housing 8 in the working position. Turn the handle of the horizontal elbow clamp 5 counterclockwise to press the side of the housing 8 that does not need to be installed with the tungsten sheet.

[0038] 2) Place the tungsten sheet 9 from above into the gap between the positioning surface B and the side of the housing 8 where the tungsten sheet needs to be installed, and slowly push it to the bottom. Then place the two tungsten sheet fixing screws 10 into the corresponding connection holes of the tungsten sheet and the housing 8. Finally, use the nut fixing tool to hold the nut 11 in place and use the tungsten sheet fixing screw 10 locking tool to lock the two sets of screws and nuts. After the tungsten sheet 9 is fixed, rotate the horizontal elbow clamp 5 clockwise to loosen it and remove the housing to proceed with the assembly of the next tilt sensor product.

[0039] In summary, this utility model mainly solves the problems of positioning the tungsten sheet 9 and fixing the tilt sensor housing 8 during assembly. The tilt sensor housing 8 is placed on the product fixing base 2, and its position is limited and fixed by the positioning surface A and the horizontal elbow clamp, which solves the problem that the housing 8 cannot be fixed during the locking process of the tungsten sheet 9. The two positioning surfaces A and B of the product fixing base 2 have a height difference H2, which solves the problem that the tungsten sheet 9 protrudes from the outer bottom surface of the housing 8 due to misalignment with the housing 8 during the locking process, which would prevent the subsequent debugging process from proceeding normally. It has high reliability, strong operability, and can be adapted to other models of tilt sensors by replacing the product fixing base 2 with other specifications, thus having strong expandability.

[0040] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
