Description

Technical Field

[0001] This utility model relates to the field of heavy metal parts inspection, specifically a multi-purpose transfer and fixing fixture. Background Technology

[0002] With the rapid development of my country's industrial production capacity across all sectors, the output and scale of industrial products have grown rapidly. However, the precision requirements of these products need to be digitally represented. The invention disclosed here is a special tooling for inspecting components of CNC lathes.

[0003] The workpieces involved are CNC lathe headstocks, which are large in size, come in many models, and are quite heavy. They require three-dimensional data inspection using equipment. Therefore, technicians typically use a coordinate measuring machine (CMM) for inspection, and the CMM table is a component of the CMM.

[0004] Existing patents, such as CN202220031609.5 (a tool for detecting the relative position of crankshaft pin holes to keyways) and CN202222152235.5 (a three-dimensional circulating loading and unloading system for measuring machines), although employing a coordinate measuring machine (CMM) for workpiece inspection, suffer from vibrations and impacts when heavy workpieces are placed directly on the CMM table, which directly damage the accuracy of the inspection equipment and the table surface. None of the aforementioned patents address these issues. Therefore, we provide a multi-purpose transfer and fixing fixture to solve these problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-purpose transfer and fixing fixture to solve the technical problem of negative impact on accuracy and table surface when heavy workpieces are placed directly on a coordinate measuring machine.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A multi-purpose transfer and fixing fixture, comprising:

[0008] A coordinate measuring machine (CMM) is equipped with a platform guide rail plate; the platform guide rail plate has a track 1.

[0009] The buffer transfer station has a second track; track one and track two are connected to each other.

[0010] A transfer trolley is installed on track two; a limiter is installed on one side of the transfer trolley, and pulleys are installed at the bottom. Multiple sets of pulleys are installed in track one or track two; a fixed support is also installed on the transfer trolley, and the workpiece is placed on the fixed support and fixed.

[0011] In a further technical solution, both track one and track two are provided in at least two sets, and multiple sets of track one or track two are arranged in parallel.

[0012] In a further technical solution, the buffer transfer station includes a bottom frame and a track plate, and a second track is provided on the track plate; a limiting block first and a limiting block second are respectively installed on the outer sides of the track first and the track second, which are opposite to each other;

[0013] Two sets of track slabs are provided and located on the top two sides of the bottom frame.

[0014] In a further technical solution, the transfer trolley includes a pallet main board, a connecting seat is installed at the bottom of the pallet main board, and a pulley is installed inside the connecting seat;

[0015] The tray main board has multiple sets of positioning holes, and the fixed support includes a positioning block, with a positioning block movably detached from the multiple sets of positioning holes; the positioning block is used to support the workpiece.

[0016] Lateral holes are provided on multiple sides of the positioning block, and a second positioning hole is provided at the bottom that matches the first positioning hole; the first positioning hole and the second positioning hole are fixed together by a positioning bolt.

[0017] In a further technical solution, the fixed support also includes a side pressure plate, which is installed on the side of the workpiece facing away from the limiting block; the side pressure plate is detachably connected to the corresponding positioning block.

[0018] In a further technical solution, the workpiece is provided with an installation groove or a connecting plate, and a position hole is provided at the bottom of the installation groove or the connecting plate; the side pressure plate is a bent plate, with a waist-shaped hole on one side and connected to the lateral hole on the positioning block by a mounting locking bolt; the top side is provided with an upper hole, and the upper hole and the position hole are connected by a top bolt.

[0019] In a further technical solution, the limiting component includes a fixed plate and a quick-release chuck. The fixed plate is fixed to the side of the main tray board facing away from the limiting block one, and the quick-release chuck is detachably connected to the fixed plate. The bottom of the quick-release chuck is used to move downwards and abut against the platform guide plate or track plate, and is located in a position other than track one or track two. The quick-release chuck, also known as a manual quick-release clamp, is a rubber pressure head type used in this application.

[0020] In a further technical solution, tubular handles are detachably installed on both sides of the tray mainboard;

[0021] Both track one and track two are downward-facing grooves, and track one and track two have the same cross-section; the bottom heights of track one and track two are the same.

[0022] In a further technical solution, polyurethane pads are installed on the bottom of the bottom frame and on both sides along the second axis of the track.

[0023] Compared with existing technologies, it has the following beneficial effects:

[0024] This invention can effectively prevent vibration and impact when heavy workpieces are placed directly on a coordinate measuring machine, thereby reducing damage to the accuracy of the testing equipment and the table surface.

[0025] The platform guide plate is fixed to the coordinate measuring machine table using hexagon countersunk bolts. This serves to guide the pulleys and limit their movement with limit blocks, while also supporting the pulleys to distribute the pressure of heavy workpieces and protecting the table surface.

[0026] After leveling and connecting the second track of the buffer transfer platform with the first track of the platform guide plate, the buffer transfer platform is fixed to the ground with anchor bolts to ensure its stability and height, support the transfer trolley and heavy workpieces, and ensure its height and position to connect with the equipment platform.

[0027] The buffer transfer platform is fixed to the ground. When a heavy workpiece is placed into the transfer trolley, its impact force is transmitted to the buffer transfer platform through the casters. The buffer transfer platform then transmits the impact force to the ground through the anchor bolts to eliminate the impact force.

[0028] The transfer trolley is equipped with pulleys, allowing it to move back and forth between the buffer transfer table and the platform guide rail; and it restricts the trolley's self-movement through a quick-locking chuck; the transfer trolley is equipped with various positioning blocks and other workpieces, which can support and fix different types of headstock housings, ensuring its versatility for different workpieces.

[0029] This invention has multiple functions, including repeated transfer, self-locking limit, and impact mitigation, which can reduce the direct damage to testing equipment caused by heavy workpieces. Attached Figure Description
