Description

Technical Field

[0001] This invention relates to the technical field of tooling, and more specifically to a product fixing device for a machining center. Background Technology

[0002] In the factory, as shown in the attached diagram of the instruction manual... Figure 1 When processing the elongated workpiece shown, it is necessary not only to mill the workpiece on the machining center, but also to remove the welding slag on multiple connecting plates on both sides of the workpiece on another device. The process involves multiple steps on multiple processing devices and multiple clamping and fixing of the workpiece using tooling fixtures. The whole process is quite cumbersome and the processing efficiency is low. Summary of the Invention

[0003] The purpose of this invention is to provide a product fixing device for a machining center to overcome the above-mentioned defects in the prior art.

[0004] A product fixing device for a machining center includes a machining center body, a clamping mechanism, and a slag removal mechanism. The machining center body has symmetrically arranged limiting seats for placing workpieces on its machining table. Several support seats are evenly distributed between the two limiting seats. Each support seat is provided with a clamping mechanism for fixing the workpiece. The slag removal mechanism removes the slag on the connecting plates on both sides of the workpiece under the drive of the pressure block on the clamping mechanism.

[0005] Preferably, the clamping mechanism includes a clamping plate, a driving cylinder, and a spring. The bent part of the clamping plate is hinged to the extended plate on the side of the support seat via a pin. The cylinder body of the driving cylinder is hinged to the inside of the support seat via a pin. The piston rod end of the driving cylinder is hinged to the lower end of the clamping plate via a pin. The pressure block is located on the inner side of the upper end of the clamping plate, and its two ends are slidably connected to the guide rod on the clamping plate. The upper and lower sides of the pressure block are symmetrically provided with driving inclined surfaces. The end of the guide rod is provided with a baffle. The spring is sleeved on the guide rod and located between the pressure block and the baffle.

[0006] Preferably, the slag removal mechanism includes a slag removal frame and a second spring. Two slag removal frames are provided and symmetrically arranged on the upper and lower sides of the pressure block. The slag removal frame is slidably connected to a slide rod in the mounting groove on the clamping plate, and the second spring is sleeved on the slide rod.

[0008] Preferably, the top of the limiting seat is provided with a limiting groove that mates with the workpiece.

[0009] Preferably, the support base has a "T" shaped structure.

[0010] The present invention has the following advantages:

[0011] When in use, the clamping block on the clamping plate of the clamping mechanism moves, driving the slag removal frame of the slag removal mechanism to remove the slag on both sides and the front side of the workpiece's connecting plate. This allows the clamping mechanism to fix the workpiece while simultaneously removing the slag from both sides of the workpiece's connecting plate, achieving two goals at once. This avoids multiple clamping of the workpiece, saves time on secondary processing, and improves the workpiece's processing efficiency. Attached Figure Description

[0021] like Figure 1-7 As shown, the present invention provides a product fixing device for a machining center, including a machining center body 1, a clamping mechanism 4, and a slag removal mechanism 5. The machining center body 1 has symmetrically arranged limiting seats 2 for placing workpieces 6 on the machining table. The top of the limiting seat 2 is provided with a limiting groove 21 that cooperates with the workpiece 6, and the workpiece 6 is limited by the limiting groove 21. Several support seats 3 are evenly distributed between the two limiting seats 2. The support seats 3 have a "T" shaped structure. Each support seat 3 is provided with a clamping mechanism 4 for fixing the workpiece 6. The slag removal mechanism 5 removes the slag on the connecting plates 61 on both sides of the workpiece 6 under the drive of the pressure block 41 on the clamping mechanism 4.

[0022] It should be noted that the clamping mechanism 4 includes a clamping plate 42, a driving cylinder 44, and a spring 47. The bent part of the clamping plate 42 is hinged to the extended plate 43 on the side of the support base 3 by a pin. The cylinder body of the driving cylinder 44 is hinged to the inside of the support base 3 by a pin. The piston rod end of the driving cylinder 44 is hinged to the lower end of the clamping plate 42 by a pin. The pressure block 41 is located on the inner side of the upper end of the clamping plate 42 and its two ends are slidably connected to the guide rod 45 on the clamping plate 42. The upper and lower sides of the pressure block 41 are symmetrically provided with driving inclined surfaces 411. The end of the guide rod 45 is provided with a baffle 46. The spring 47 is sleeved on the guide rod 45 and located between the pressure block 41 and the baffle 46.

[0023] In addition, the slag removal mechanism 5 includes a slag removal frame 51 and a second spring 54. The slag removal frame 51 has two parts and is symmetrically arranged on the upper and lower sides of the pressure block 41. The slag removal frame 51 is slidably connected to the slide rod 53 in the mounting groove 52 on the clamping plate 42. The second spring 54 is sleeved on the slide rod 53. The slag removal frame 51 includes a side slag removal plate 511 and a front slag removal plate 512. The two side slag removal plates 511 are connected by the front slag removal plate 512. The side of the front slag removal plate 512 is provided with a connecting ear 513 that is slidably connected to the slide rod 53. The front slag removal plate 512 is provided with a pressing inclined surface 514 that cooperates with the driving inclined surface 411 on the pressure block 41. The top of both the side slag removal plate 511 and the front slag removal plate 512 is provided with a blade.

[0024] Detailed implementation methods and principles:

[0025] In practical application, the workpiece 6 to be processed is placed at both ends in the limiting grooves 21 of the limiting seat 2 of the machining center body 1. Then, the piston rod of the control cylinder is extended to drive the clamping plate 42 to rotate. The side slag removal plate 511 on the slag removal frame 51 contacts the connecting plate 61 on the side of the workpiece 6. During the movement, the side of the connecting plate 61 of the workpiece 6 is polished. When the pressure block 41 on the clamping plate 42 contacts the connecting plate 61, the pressure block 41 slides along the guide rod 45 under the action of pressure. The spring 47 on the guide rod 45 is compressed. The pressure block 41 drives the slag removal frames 51 on its upper and lower sides to move to the sides through the driving inclined surface 411. During the movement of the slag removal frame 51, the welding slag at the welding point between the side and front sides of the connecting plate 61 and the workpiece 6 is removed by the side slag removal plate 511 and the front slag removal plate 512. After the welding slag on the connecting plate 61 is removed, the workpiece 6 is finally fixed by the pressure block 41. Then, the workpiece 6 is processed by the machining center.

[0026] In summary, the present invention, through the movement of the pressure block 41 on the clamping plate 42 of the clamping mechanism 4, drives the slag removal frame 51 of the slag removal mechanism 5 to remove the slag on both sides and the front side of the connecting plate 61 of the workpiece 6. Thus, the clamping mechanism 4 can fix the workpiece 6 while removing the slag on both sides of the connecting plate 61 of the workpiece 6, achieving two goals at once, avoiding multiple clamping of the workpiece 6, saving secondary processing time, and thus improving the processing efficiency of the workpiece 6.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
