Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an adjustable height mechanism support structure. Background Technology

[0002] In the field of reaming machines, the mechanism support plate, as a core component for supporting and fixing the mechanism, directly affects the accuracy, efficiency, and safety of mechanism installation due to the rationality of its structural design. In existing technologies, the height of the mechanism platform in reaming machines varies, and there are inconsistencies in the slope between some mechanism platforms and the mechanism support plate. Traditional solutions typically involve temporarily placing objects (such as metal blocks or wooden wedges) under the front legs of the mechanism support plate, adjusting the thickness of the padding to compensate for height or slope differences.

[0003] The selection of padding materials depends on the operator's experience and the available materials on site, making it difficult to achieve precise and accurate height adjustments. This can easily lead to deviations in the installation position of the mechanism, affecting the equipment's operational accuracy and product quality. The process of finding suitable padding materials, repeatedly testing padding, and making adjustments is tedious and time-consuming, significantly reducing installation efficiency and slowing down the overall production pace. Furthermore, temporary padding materials are prone to displacement, loosening, or even falling off during equipment operation, resulting in unstable support of the mechanism support plate and posing risks to equipment damage and personnel safety. Utility Model Content

[0004] In view of the problem that the existing hole reamer's core platform and core support plate are not at the same height, requiring manual adjustment of the slope by padding during installation, which is cumbersome and has poor stability, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an adjustable height movement support structure, which aims to improve the efficiency of movement installation and ease of operation.

[0006] To solve the above technical problems, the present invention provides the following technical solution: an adjustable height mechanism support structure, including a support platform, with rear leg columns welded to both ends of one side of the bottom of the support platform, and front leg columns welded to both ends of the other side of the top of the support platform, and a corner pad assembly detachably installed on the top of the support platform between the two front leg columns. The corner support assembly includes a U-shaped frame that is detachably installed at the bottom of the support platform. The U-shaped frame has a vertically lifting bar installed inside, and both ends of the bottom of the lifting bar are fixed with support legs.

[0007] As an improved technical solution, a stop bar is welded to the top of the support platform and one end near the rear leg column, and the four sides of the support platform are integrally formed with protruding edges.

[0008] As an improved technical solution, a lead screw is rotatably installed in the middle of the top of the inner wall of the U-shaped frame, and a threaded hole for threaded connection with the lead screw is opened in the middle of the lifting bar, and the lifting bar is vertically slidably installed inside the U-shaped frame.

[0009] As an improved technical solution, guide rails are fixed on both sides inside the U-shaped frame, and sliding grooves are opened at both ends of the lifting bar to slide on the guide rails.

[0010] As an improved technical solution, a stop post is coaxially welded to the end of the lead screw near the pad leg, and three protruding rods are welded at equal intervals on the periphery of the stop post. A hexagonal groove is provided at the end of the stop post away from the lead screw.

[0011] As an improved technical solution, two threaded recesses are provided at the bottom of the support platform and on the side near the front leg column. Hexagonal bolts are threaded into the support platform through the threaded recesses, and fixing holes for the hexagonal bolts to pass through are provided on both sides of the top of the U-shaped frame.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: 1. This utility model allows the U-shaped frame to be detachably installed inside the support platform via hexagonal bolts and threaded installation. This makes the corner pad assembly detachably installed at the bottom of the support platform, facilitating its installation. Furthermore, since the corner pad assembly is detachably installed inside the support platform, if any part of the bracket or corner pad assembly is damaged, it can be replaced according to the actual damaged part, thus reusing resources and avoiding waste.

[0013] 2. This utility model enables stepless, precise, and continuous adjustment of the platform height through a simple threaded transmission operation. The operation is intuitive and convenient, eliminating the need for repeated testing, significantly improving installation accuracy and efficiency, effectively avoiding installation deviations, and featuring a simple structure that is easy to process and promote. At the same time, it completely eliminates the reliance on temporary pads. After adjustment, the self-locking characteristic of the threaded pair can firmly lock the adjusted height. Furthermore, it can flexibly adapt to different models of reaming machines with different height core platforms, significantly improving the versatility of the pallet structure.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-3 This is the first embodiment of the present utility model, which provides an adjustable height mechanism tray structure. This adjustable height mechanism tray structure includes a support platform 1. Rear leg posts 4 are welded to both ends of one side of the bottom of the support platform 1, and front leg posts 5 are welded to both ends of the other side of the top of the support platform 1. The height of the front leg posts 5 is higher than the height of the rear leg posts 4. A corner pad assembly 6 is detachably installed on the top of the support platform 1 and between the two front leg posts 5. The corner support assembly 6 includes a U-shaped frame 61 that is detachably installed at the bottom of the support platform 1. A lifting bar 66 is vertically installed inside the U-shaped frame 61, and both ends of the bottom of the lifting bar 66 are fixed with a foot 69.

[0020] A retaining strip 3 is welded to the top of the support platform 1 and to one end near the rear leg column 4. The four sides of the support platform 1 are integrally formed with protruding edges 2.

[0021] A lead screw 65 is rotatably installed in the middle of the top of the inner wall of the U-shaped frame 61. A threaded hole for threaded connection with the lead screw 65 is opened in the middle of the lifting bar 66. The lifting bar 66 is vertically slidably installed inside the U-shaped frame 61. The height of the front leg column 5 is adjusted by the lead screw 65, so that the slope of the movement platform and the movement support plate can be consistent. This makes it very convenient to install the movement, saving time and effort, and improving the efficiency and ease of operation of the movement installation.

[0022] The U-shaped frame 61 has guide rails 62 fixed on both sides inside, and the lifting bar 66 has sliding grooves 63 at both ends that slide on the guide rails 62.

[0023] During use, the height of the support platform 1 can be adjusted steplessly, precisely, and continuously through simple threaded transmission. The operation is intuitive and convenient, eliminating the need for repeated testing, which significantly improves installation accuracy and efficiency, effectively avoids installation deviations, and has a simple structure that is easy to process and promote. At the same time, it completely eliminates the reliance on temporary pads. After adjustment, the self-locking property of the threaded pair can firmly lock the adjusted height, preventing loosening or settling even under equipment vibration conditions. This greatly ensures the stability and safety of the mechanism installation and operation, eliminates the safety hazards caused by pad falling off, and can flexibly adapt to different models of hole expanders with different height mechanism platforms, significantly improving the versatility of the pallet structure.

[0024] Example 2 Reference Figures 2-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a stop post 67 is coaxially welded to one end of the lead screw 65 near the pad leg 69. Three protrusions 68 are welded at equal intervals on the periphery of the stop post 67. A hexagonal groove is provided at the end of the stop post 67 away from the lead screw 65. The lead screw 65 can be driven to rotate by using an internal hexagonal wrench to engage with the hexagonal groove at the bottom of the stop post 67. With the option of using the protrusions 68 and the hexagonal wrench, the method of driving the lead screw 65 can be selected according to the actual situation, which facilitates the rotation of the lead screw 65.

[0025] Two threaded recesses 7 are provided at the bottom of the support platform 1 and on the side near the front leg column 5. The two threaded recesses 7 are located between the two front leg columns 5. Hex bolts 8 are threadedly installed on the support platform 1 through the threaded recesses 7. Fixing holes 64 for the hex bolts 8 to pass through are provided on both sides of the top of the U-shaped frame 61.

[0026] During use, the corner pad assembly 6 is detachably installed inside the support platform 1. If the tray or a part of the corner pad assembly 6 is damaged, it can be replaced according to the actual damaged part, so as to reuse the resources and avoid waste.

[0027] The remaining structure is the same as that in Example 1.

[0028] Based on embodiments 1-2, the working principle of this utility model is as follows: The process of installing the corner pad assembly 6 at the bottom of the support platform 1 is as follows: After the hex bolt 8 passes through the fixing hole 64, it is screwed into the threaded recess 7. The U-shaped frame 61 is detachably installed inside the support platform 1 by the threaded installation of the hex bolt 8 and the support platform 1, so that the corner pad assembly 6 is detachably installed at the bottom of the support platform 1, which makes it easy to install the corner pad assembly 6 at the bottom of the support platform 1. By using the hand-held protruding rod 68 to drive the lead screw 65 to rotate, under the longitudinal thread transmission action of the lead screw 65 and the threaded hole on the lifting bar 66, the lifting bar 66 is driven to move vertically, thereby driving the pad leg 69 to move vertically and adjusting the bottom of the pad leg 69 to be flush with the front leg column 5. At this time, it is the initial state of the pallet structure, that is, the pad corner assembly 6 has not adjusted the height of the support platform 1. Then, the drive screw 65 rotates, which drives the pad leg 69 to move downward through the lifting bar 66, lifting the front leg column 5 upward. The height of the front leg column 5 is then finely adjusted until the convex edge 2 is consistent with the slope of the movement platform, thus completing the installation of the movement.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
