Description

Technical Field

[0001] The utility model relates to the technical field of chassis punching, and particularly relates to a chassis processing punching machine. Background Technique

[0002] The chassis processing technology includes shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its remarkable feature is that the thickness of the same part is consistent. With the increasingly wide application of sheet metal, the design of sheet metal parts has become a very important part in the industrial development of products; when punching the chassis, since the sheet metal chassis belongs to a hollow structure, when the drill bit of the punching machine punches the sheet metal chassis, the pressure and impact force generated are likely to cause the sheet metal chassis to deform, thus affecting the quality of the sheet metal chassis.

[0003] The utility model patent CN217912958U discloses a punching machine for a sheet metal chassis, which relates to the technical field of punching equipment. The utility model includes a bottom plate, a side plate is installed on the upper side of the bottom plate, and a punching device is installed on the upper side of the side plate; two wooden boards are slidably matched on one side of the side plate, a threaded rod matched with the two wooden boards is rotatably matched in the side plate, a groove is opened on one side of the bottom plate, and a pedal in transmission cooperation with the threaded rod is rotatably matched in the groove;

[0004] Through the two wooden boards provided, the two sides of the inner wall of the sheet metal chassis can be supported, reducing the possible deformation of the sheet metal chassis when the punching device punches the sheet metal chassis; however, when the two wooden boards support the inner wall of the chassis, if the supporting force is insufficient, the vibration generated during punching may cause the chassis to come out. If the supporting force is too large, it may cause the chassis to deform, thus causing damage to the chassis. Content of the Utility Model

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a chassis processing punching machine. When punching holes in the chassis, the chassis is placed on the second clamping plate so that the inner upper side wall of the chassis abuts against the side surface of the second clamping plate.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 , the embodiment proposed in the present application is: a chassis processing punching machine, including a support seat 1, a side plate 2 is vertically provided on the left side of the upper side of the support seat 1, a punching machine 3 for punching holes is provided at the upper side of the side plate 2 corresponding to the support seat 1, the punching machine 3 here is a conventional punching machine 3 in the prior art, which will not be described here, a first clamping plate 4 is transversely fixedly provided on the right side of the side plate 2, a clearance hole 41 is opened in the middle of the first clamping plate 4 corresponding to the punching machine 3, a second clamping plate 5 is transversely provided on the lower side of the first clamping plate 4, and a driving structure 6 drivingly connected to the second clamping plate 5 is provided in the side plate 2 corresponding to the second clamping plate 5;

[0021] When punching holes in the chassis, first put the chassis on the second clamping plate 5, and place the surface to be punched on the upper side of the second clamping plate 5. The second clamping plate 5 can be driven by the driving structure 6 to drive the chassis to rise until it is in contact with the first clamping plate 4. When clamping, it will not cause deformation to the chassis, and it can effectively clamp it stably when vibration occurs during drilling, thereby improving the quality of chassis punching.

[0022] In another embodiment, see Figure 1-2 The driving structure 6 includes a vertically arranged threaded rod 61, and a movable groove 21 is longitudinally opened on the right side of the side plate 2 corresponding to the threaded rod 61. The two ends of the threaded rod 61 are rotatably inserted in the upper and lower sides of the movable groove 21. The left side of the second clamping plate 5 is slidably arranged in the movable groove 21 and is threadedly connected with the threaded rod 61. A driving motor 62 is provided at the upper end of the corresponding threaded rod 61 in the side plate 2. The driving motor 62 is drivingly connected to the threaded rod 61. By starting the driving motor 62, the threaded rod 61 is driven to rotate, so that the second clamping plate 5 threadedly connected with the threaded rod 61 is raised until it abuts against the first clamping plate 4, thereby clamping and fixing the surface to be punched of the chassis. After the punching is completed, the chassis is removed by reversing the driving motor 62. The positive and reverse rotation of the driving motor 62 here is a prior art and will not be repeated here.

[0023] In this embodiment, a limiting slider 51 fixedly connected to the left side of the second clamping plate 5 corresponding to the movable slot 21 and slidably connected to the movable slot 21 is provided. The threaded rod 61 passes through the limiting slider 51 and is threadedly connected thereto. The limiting slider 51 is used here so that it will not rotate or shake when sliding up and down in the movable slot 21. An L-shaped reinforcing rib 52 is provided on the lower side surface of the second clamping plate 5. One side of the L-shaped reinforcing rib 52 is fixedly connected to the lower side surface of the second clamping plate 5, and the other side is fixedly connected to the limiting slider 51, which increases the strength of the second clamping plate 5 and also ensures the flatness of the second clamping plate 5, enabling it to better fit with the first clamping plate 4 and achieve better clamping.

[0024] In another embodiment, please refer to Figure 1-2 , a pull rod 22 is fixedly provided obliquely at the upper end of the right side surface of the side plate 2, and the right side of the pull rod 22 is fixedly connected to the upper side surface of the first clamping plate 4, which increases the flatness and strength of the first clamping plate. At the same time, anti-slip pads 7 are provided on the opposite sides of the first clamping plate 4 and the second clamping plate 5, which increases the clamping friction and makes the clamping more stable.
