Description

Technical Field

[0001] This utility model relates to the field of processing fixtures, and in particular to a drawer-type automatic telescopic fixture structure for laser marking. Background Technology

[0002] In machining and some laser processing applications, products need to be positioned and fixed using appropriate fixtures before precision machining. Current automatic fixture boxes use belt conveyors, which are bulky, difficult to seal, and inconvenient to install, debug, and maintain. Furthermore, the industrial aluminum profile guide rails used have short lifespans, and components require precise fit for smooth sliding, making them prone to damage. This can cause malfunctions in the automatic opening and closing of drawer-type fixtures, leading to jamming and damage of the aluminum profile guide rails during equipment handling or transportation. Some systems use multiple drives to control the fixture's movements, increasing costs and further expanding the overall size of the fixture equipment.

[0003] In view of this, this technical solution proposes a structure that uses a single motor to drive gears and racks, and adopts double-sided guide rods. This not only reduces the overall size and manufacturing cost of the equipment, but also has the characteristics of quick fixture replacement and improved overall processing efficiency. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a drawer-type automatic telescopic fixture structure for laser marking, aiming to solve the problems of complex transmission structures, frequent malfunctions, and short service life in existing fixtures.

[0005] To achieve the above objectives, this utility model provides a drawer-type automatic telescopic fixture structure for laser marking, including a fixture transmission assembly disposed within an outer housing. The jig transmission assembly includes a motor located at the bottom of the outer casing and a gear driven by the motor. One side of the gear is meshed with a rack, and a movable plate is connected to one side of the rack. A slider is provided on one side of the movable plate, and the slider runs on a guide rail parallel to the rack. The movable plate has a connector at one end, which connects to the tail of the carrier plate. The bottom of the carrier plate has a guide rod parallel to the guide rail and the gear rack. The carrier plate also has a fixture body. The carrier plate, through the cooperation of the gears, racks, movable plate, connector, and guide rod, enables the automatic entry and exit of the fixture body from the outer casing.

[0006] As a further embodiment of this utility model, the outer casing is provided with a main compartment door for taking out and putting in fixtures and products, and the bottom of the main compartment door is provided with an automatic door corresponding to the carrier plate and fixture body.

[0007] As a further embodiment of this utility model, a processing cavity for laser marking is provided above the carrier plate and the main body of the fixture.

[0008] As a further improvement of this utility model, the carrier plate is provided with positioning posts for quickly positioning the main body of the fixture.

[0009] As a further embodiment of this utility model, the guide rod is provided on both sides of the bottom of the carrier plate, and the guide rod is a ball bearing guide rod structure.

[0010] As a further improvement of this utility model, the bottom of the carrier plate is provided with a positioning sensor for sensing the running distance.

[0011] As a further embodiment of this utility model, the bottom of the outer cover is provided with a base plate, the jig transmission assembly is embedded in the base plate, the bottom of the base plate is provided with a bottom frame, and the bottom of the bottom frame is provided with a foot cup.

[0012] The beneficial effects of this utility model are as follows: This technical solution uses a single motor to drive a gear. The gear meshes with a rack to drive a movable plate. The slider on the movable plate slides linearly along the guide rail. The movable plate then pulls a carrier plate through a connector. The guide rod at the bottom of the carrier plate ensures smooth movement, ultimately realizing the automatic entry and exit of the fixture body within the outer casing. This integrated transmission structure simplifies the complexity of traditional multi-drive systems and eliminates the defects of belt transmission or aluminum profile guide rails that are prone to jamming and damage, thereby significantly reducing the failure rate and extending service life. Furthermore, combined with ball-type guide rods and position sensors, the operation is smoother and more precise, avoiding overshoot or positioning deviation, and reducing equipment size and manufacturing costs. Overall, it enhances processing efficiency, maintenance convenience, and operational reliability. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see the appendix Figure 1-9 , The main structure consists of a jig transmission assembly (11) located inside the outer casing (10). This assembly includes a motor (110) located at the bottom of the casing, which drives a gear (111) to rotate. One side of the gear (111) meshes with a rack (112), which in turn is directly connected to one side of a movable plate (113). A slider (1140) is mounted on one side of the movable plate (113), and the slider (1140) moves along a path that... The rack (112) slides parallel to the guide rail (114) to ensure that the movable plate (113) moves in a straight line. The other end of the movable plate (113) is provided with a connector (115), which is firmly connected to the tail of the carrier plate (117). Guide rods (116) are installed on both sides of the bottom of the carrier plate (117). The guide rods (116) are parallel to the guide rail (114) and the rack (112). The fixture body (119) is placed on the carrier plate (117).

[0027] In actual operation, for example, when the motor (110) starts, the gear (111) rotates and drives the rack (112) to move. The rack (112) pushes the movable plate (113) to slide linearly along the guide rail (114). The movable plate (113) pulls or pushes the carrier plate (117) through the connector (115). At the same time, the guide rod (116) guides the carrier plate (117) to move smoothly, so that the main body of the fixture (119) automatically extends or retracts the outer cover (10) like a drawer, realizing the entry and exit of the chamber.

[0028] The above-mentioned innovative structure and actual operation mode solve the technical problems of complex transmission structure, easy failure and short service life in the existing technology. It can be understood that, due to the use of single motor (110) drive and guide rod (116) structure, the overall structure is compact, which greatly reduces the size of the equipment and manufacturing cost. At the same time, the guide rod (116) can ensure smooth sliding and durability, avoiding the risk of jamming or damage of traditional aluminum profile guide rail (114). Combined with the positioning column (105) on the carrier plate (117), the main body of the fixture (119) can be quickly replaced, improving processing efficiency. Overall, the maintenance process is simplified and the reliability and practicality are enhanced.

[0029] Reference Appendix Figure 8 , 9 In a preferred embodiment of this utility model, the outer casing (10) is provided with two door structures, namely the upper main compartment door (103) for whole machine maintenance or quick replacement of the fixture body (119) and product, and the bottom automatic door (104) corresponds to the position of the carrier plate (117) and the fixture body (119).

[0030] Specifically, when the fixture body (119) retracts into the outer casing (10) via the fixture transmission assembly (11), the automatic door (104) immediately closes the sealed compartment, while the main compartment door (103) remains normally closed and is only opened for maintenance, increasing the airtightness of the processing and preventing external dust from interfering with precision operations (such as laser marking). The immediate response of the automatic door (104) also avoids manual intervention, simplifying the daily maintenance process.

[0031] Reference Appendix Figure 2 In a preferred embodiment of this utility model, the fixture box body (1) can accommodate the processing cavity (100). The processing cavity (100) is directly positioned above the carrier plate (117) and the fixture body (119). When the carrier plate (117) carrying the fixture body (119) is fully inserted into the outer cover (10) through the fixture transmission assembly (11), the product is automatically positioned directly below the processing cavity (100). At this time, the laser marking equipment can immediately perform processing operations on the product.

[0032] Reference Appendix Figure 9 In a preferred embodiment of this utility model, the positioning post (105) is vertically fixed on the surface of the carrier plate (117). When the operator changes the fixture body (119), the corresponding mounting hole at the bottom of the fixture is inserted into the positioning post (105) to complete the precise positioning, so that the fixture replacement operation is quick.

[0033] Reference Appendix Figure 5 In a preferred embodiment of this utility model, the guide rod (116) is fixedly installed on both sides of the bottom of the carrier plate (117) and adopts a ball bearing guide rod structure.

[0034] Specifically, the double-sided ball bearing guide rod design achieves ultra-low friction sliding when the carrier plate (117) extends and retracts by forming rolling balls inside, which makes the jig body (119) move smoothly in and out of the chamber. This avoids the problems of deformation, jamming or damage of traditional industrial aluminum profile guide rails (114), thus significantly extending the service life in frequent operation or equipment handling scenarios.

[0035] Reference Appendix Figure 5 In a preferred embodiment of this utility model, a positioning sensor (118) is provided at the bottom of the carrier plate (117), which is mainly used to monitor the moving distance of the carrier plate (117) in real time, detect the position of the carrier plate (117) on the guide rod (116), and ensure that the main body of the fixture (119) automatically stops at the set position when entering and leaving the chamber.

[0036] Reference Appendix Figure 3 , 4 In a preferred embodiment of this utility model: preferably, the bottom of the outer cover (10) is provided with a base plate, and a grid is cut out on the base plate. The entire jig transmission assembly (11) can be embedded on the base plate to fix all moving parts. The entire jig transmission assembly can be made thinner. The bottom of the base plate is connected to the bottom frame (1010) to frame and encapsulate the upper parts. A foot cup (102) is installed at the bottom of the bottom frame (1010) to provide shock absorption and ground leveling functions.

[0037] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0038] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0039] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
