Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an exchange worktable for machining. Background Technology

[0002] In the field of machining, workpiece loading and unloading are crucial steps in the production process, directly impacting machining efficiency and accuracy. Traditional machining worktables typically employ a single, fixed loading method, where the workpiece is placed in a fixed position and then moved to the machining area manually or using mechanical equipment by the operator. This method is not only inefficient but also prone to errors during loading, affecting machining accuracy. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an exchange worktable for machining, which solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a machining exchange worktable, including a machining equipment, the upper part of which is provided with a machining area, and a base plate is fixedly installed at the front end. The front end of the base plate is slidably connected to multiple sets of loading worktables through linear guide rails. Each set of loading worktables is provided with a workpiece fixture, and a machining platform is installed in the machining area of ​​the machining equipment. The multiple sets of loading worktables can sequentially transport the workpiece fixture to the machining platform.

[0005] Furthermore, the linear guide rails are symmetrically installed at the front end of the base plate to reduce the frictional resistance when the loading worktable slides.

[0006] Furthermore, each set of the loading worktable includes a table frame that is slidably disposed at the front end of the base plate, and a set of loading rollers is symmetrically installed on the upper part of the table frame for supporting the workpiece fixture.

[0007] Furthermore, a female alignment seat is fixedly installed at one front end of the seat plate, and a male alignment head is installed at one rear end of the frame of each set of feeding worktables. The female alignment seat and the male alignment head are engaged and aligned through elastic deformation.

[0008] Furthermore, the female connector is provided with a female groove, and the male connector is provided with a male protrusion that matches the female groove.

[0009] Furthermore, the processing platform includes a second platform frame installed in the processing area of ​​the machining equipment. The top of the second platform frame is provided with a clearance hole, and a cylinder is installed at the bottom. The telescopic end of the cylinder extends to the upper part of the second platform frame through the clearance hole and is equipped with a set of unloading rollers.

[0010] Furthermore, the workpiece fixture is provided with pin holes on both sides, and the second platform frame is provided with positioning pins that are compatible with the pin holes on both sides. The second platform frame is provided with a stop baffle at the rear end to prevent the workpiece fixture from overstepping its bounds.

[0011] Furthermore, the cylinder drives the unloading roller assembly to move up and down to support or release the workpiece fixture. The positioning pin is inserted into the pin hole after the workpiece fixture is in place to prevent the workpiece from shifting.

[0012] This utility model provides an exchange worktable for machining. Compared with the prior art, it has the following advantages:

[0013] This machining exchange table, employing linear guides and multiple sets of sliding loading tables, enables rapid and flexible workpiece fixture scheduling. Operators can easily push any set of loading tables to the machining platform to complete workpiece loading and unloading operations, significantly shortening workpiece exchange time and thus substantially improving overall machining production efficiency.

[0014] Furthermore, the precise engagement design of the alignment female and male connectors ensures the stability and accuracy of the workpiece fixture during transport. This design effectively avoids displacement deviations caused by inaccurate positioning during machining, thereby significantly improving machining accuracy and guaranteeing product quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a machining exchange worktable, including a machining equipment 1, a base plate 2 fixedly installed at the front end of the machining equipment 1, and a number of loading worktables 4 slidably connected to the front end of the base plate 2. Each loading worktable 4 has a workpiece fixture 5 placed on its upper part. A machining platform 6 is installed in the machining area of ​​the machining equipment 1. The multiple loading worktables 4 can all transport the workpiece fixture 5 to the machining platform 6, and at the same time, only one loading worktable 4 can transport the corresponding workpiece fixture 5 to the machining platform 6.

[0025] The front end of the seat plate 2 is slidably connected to several sets of feeding worktables 4 through linear guide rails 3. The linear guide rails 3 are symmetrically installed at the front end of the seat plate 2. The linear guide rails 3 can reduce the frictional resistance and make the sliding of each set of feeding worktables 4 smoother, thus reducing the workload of the staff in pushing the feeding worktables 4.

[0026] Each set of loading worktables 4 includes a table frame 41 that is slidably set at the front end of the seat plate 2. Loading roller sets 42 are symmetrically installed on the upper part of the table frame 41. The loading roller sets 42 support the workpiece fixture 5. During the loading and unloading process, the loading roller sets 42 can reduce the friction between the workpiece fixture 5 and the table frame 41, making it convenient to push and pull the workpiece fixture 5.

[0027] A female alignment seat 21 is fixedly installed at the front end of the seat plate 1 2. The position of the female alignment seat 21 corresponds to the middle of the processing platform 6. A second seat plate 43 is fixedly installed at the rear end of the platform frame 1 41. A male alignment head 44 is fixedly installed at the rear end of the second seat plate 2 43. A female alignment groove 22 and a male head protrusion 45 are provided at the adjacent ends of the female alignment seat 21 and the male alignment head 44, respectively. Both the female alignment seat 21 and the male alignment head 44 are components that can undergo elastic deformation. The male head protrusion 45 can be engaged inside the female alignment groove 22, and the two are compatible.

[0028] The machining platform 6 includes a second platform frame 61 installed in the machining area of ​​the machining equipment 1. A clearance hole 62 is pre-drilled at the top of the second platform frame 61, and a cylinder 64 is fixedly installed at the bottom of the second platform frame 61. The telescopic end of the cylinder 64 extends through the clearance hole 62 to the upper part of the second platform frame 61, where a feeding roller assembly 63 is installed and fixed. The feeding roller assembly 63 also supports the workpiece fixture 5. Pin holes 51 are pre-drilled on both sides of the workpiece fixture 5, and positioning pins 65 are fixedly installed on both sides of the second platform frame 61. The position, shape, and size of the pin hole 51 and the positioning pin 65 are compatible. A stop baffle 66 is installed at the rear end of the platform frame 2 61. The stop baffle 66 can prevent the workpiece fixture 5 from overstepping its position when it is loaded. Before loading, the cylinder 64 pushes the unloading roller group 63 to move upward. Then the workpiece fixture 5 is pushed to the upper part of the platform frame 2 61 and supported by the unloading roller group 63. After the workpiece fixture 5 is in place, the cylinder 64 drives the unloading roller group 63 to descend. After descending, the positioning pin 65 is inserted into the pin hole 51 to prevent the workpiece from shifting during the processing.

[0029] When the exchange worktable is in operation, each set of loading worktables 4 has a workpiece fixture 5 mounted on its upper part. The workpiece to be processed is fixed on the workpiece fixture 5 (not shown in the figure). The operator moves any set of loading worktables 4 laterally to a position corresponding to the processing platform 6, and then pushes the workpiece fixture 5 mounted on that set of loading worktables 4 onto the processing platform 6. During the pushing process, when the loading worktable 4 moves to correspond with the processing platform 6, the male protrusion 45 and the alignment female groove 22 will engage with each other, playing a positioning role, thereby... To improve the accuracy of loading, after the workpiece is processed, the operator pulls the workpiece fixture 5 back from the processing platform 6 to the loading worktable 4, and then moves the loading worktable 4 away. During the removal process, because the alignment female seat 21 and the alignment male head 44 are components that can undergo elastic deformation, the operator can easily disengage the male head protrusion 45 from the alignment female groove 22 with a little force, thereby calling other loading worktables 4 for loading. This process is repeated in a cycle, which can efficiently and quickly complete the task of loading and unloading workpieces during the machining process.
