A quick-change universal tray

Abstract

This utility model provides a quick-change universal pallet, relating to the field of machining technology, to solve the problems of existing pallets requiring corresponding threaded holes and pin holes for mounting tooling fixtures. Often, one pallet can only correspond to one type of tooling fixture, resulting in significant limitations in use. Furthermore, after prolonged use, the threaded holes are prone to wear, leading to pallet failure and poor practicality. The invention includes a main body with through holes; a bushing at the top of the through hole; and a threaded sleeve at the bottom of the through hole. The multiple through holes on the main body allow for compatibility with various types of tooling fixtures. The bushing and threaded sleeve have an interference fit with the through holes, ensuring stable installation. This allows for quick replacement of different types of tooling fixtures. The separate design of the bushing and threaded sleeve means that if the pin hole wears and becomes inaccurate in positioning, or if the thread wears and the tooling becomes loose after prolonged use, simply replacing the corresponding bushing and threaded sleeve will solve the problem, greatly reducing time and cost.

Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and more specifically, it relates to a quick-change universal pallet. Background Technology

[0002] In the machining process, it is necessary to fix the produced parts. The fixture is usually installed on the pallet by threads, and this device is needed at this time.

[0003] Based on existing technology, it has been found that the existing pallets require corresponding threaded holes and pin holes to mount tooling fixtures. Often, one pallet can only correspond to one type of tooling fixture, which has a great limitation. After long-term use, the threaded holes are prone to wear, which can cause the pallet to fail and has poor practicality. In addition, the pallets are equipped with handles for easy handling, but the handles can interfere with the machining equipment during the processing and cannot be easily disassembled. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a quick-change universal pallet. This solves the problem that existing pallets require corresponding threaded holes and pin holes to mount tooling fixtures, often resulting in one pallet being compatible with only one type of tooling fixture, which greatly limits their use. Furthermore, after prolonged use, the threaded holes are prone to wear, leading to pallet failure and poor practicality. Additionally, pallets are often equipped with handles for easy handling, but these handles can interfere with machining equipment during processing, making disassembly difficult.

[0005] This utility model provides a quick-change universal tray, achieved through the following specific technical means: A quick-change universal tray, comprising a main body; The main body is a universal tray body; the main body is provided with a through hole; a bushing is provided at the top of the through hole; a toothed sleeve is provided at the bottom of the through hole; sliding grooves are provided on both sides of the main body; push blocks are slidably arranged inside the sliding grooves; inserts are provided on the push blocks; the inserts are slidably arranged inside the round holes on both sides of the main body; springs are provided on the push blocks; the springs are connected to the main body; sliders are slidably arranged inside the sliding grooves; inserts are provided inside the round holes on the sliders; handles are provided on the sliders.

[0006] Furthermore, the main body is configured as a rectangular plate structure; the spacing between the through holes is set to 50mm; and a pull stud is provided at the bottom of the main body.

[0007] Furthermore, the bushing has a circular hole inside; the diameter of the bushing hole is set to 16mm; the bushing is interference-fitted with the through hole.

[0008] Furthermore, the dental sleeve has a threaded hole inside; the nominal diameter of the dental sleeve is set to 12mm; the dental sleeve and the bushing are interference fit; the dental sleeve and the through hole are interference fit.

[0009] Furthermore, the push block is configured as a T-shaped structure; a spring is fitted onto the plug-in.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This device is equipped with bushings and threaded sleeves, which are installed inside the through holes. Through the multiple sets of through holes on the main body, it can be compatible with various types of tooling fixtures. The bushings and threaded sleeves are interference-fitted with the through holes to achieve stable installation. It can be used for quick replacement of different types of tooling fixtures. The bushings and threaded sleeves are designed separately. If the pin hole wears and the positioning is inaccurate after long-term use, or if the thread wears and the tooling is not secure, simply replace the corresponding bushings and threaded sleeves to solve the problem, which greatly reduces time and cost. The pull stud at the bottom can be connected with the zero-point positioner to achieve quick clamping. 2. In this device, a plug and a slider are provided. The plug is set on the push block, and the slider is set inside the slide groove. Thus, when in use, by manually pulling the two sets of push blocks, the push blocks drive the plug to move and stretch the spring, causing the push blocks to move relative to each other, thereby causing the plug to disengage from the slider, so that the handle can be easily removed.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0017] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a quick-change universal tray, including a main body 1; The main body 1 is a universal tray body; the main body 1 is provided with through holes 2; a bushing 3 is provided at the top of the through hole 2; a toothed sleeve 4 is provided at the bottom of the through hole 2; sliding grooves 5 are provided on both sides of the main body 1; push blocks 6 are slidably arranged inside the sliding grooves 5; inserts 7 are provided on the push blocks 6; inserts 7 are slidably arranged inside the round holes on both sides of the main body 1; springs 8 are provided on the push blocks 6; springs 8 are connected to the main body 1; sliders 9 are slidably arranged inside the sliding grooves 5; inserts 7 are provided inside the round holes on the sliders 9; handles 10 are provided on the sliders 9; the main body 1 here is used to install bushings 3 and toothed sleeves 4 through the through holes 2, and the spacing of the through holes 2 is set to 50mm, so that it can be compatible with various types of trays during use. The tooling fixture is of the model number; the bushing 3 is used to connect with the pin of the fixture through the set round hole to achieve the effect of initial positioning of the fixture, and the threaded sleeve 4 is used to connect with the bolt on the fixture through the internal threaded hole. Both bushing 3 and threaded sleeve 4 are installed by interference fit with the through hole 2, and are installed by external press-in. If either bushing 3 or threaded sleeve 4 is damaged, it can be removed and replaced by tools, saving time. The slide groove 5 is used to connect with the slider 9, and the push block 6 is used to move the plug 7 by manually pulling it to limit or unlock the slider 9, thereby realizing the disassembly and installation of the handle 10.

[0018] Among them, such as Figure 1 As shown, the main body 1 is set as a rectangular plate structure; the spacing of the through holes 2 is set to 50mm; a pull stud 11 is provided at the bottom of the main body 1; the pull stud 11 here is used to cooperate with the external zero point positioner to achieve quick clamping and positioning, and the working principle of the connection between the pull stud 11 and the part positioner is common knowledge in the field.
