DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0021] See also Figure 1-Figure 4 A chamfering device for processing a vehicle threshold beam comprises a bearing plate 1 arranged above the vehicle threshold beam 6, a gear 2 rotatably arranged on the bearing plate 1, a rack 1 3 and a rack 2 4 respectively meshing with the gear 2, a drilling chamfering assembly arranged at one end of the rack 1 3, and a measuring assembly arranged at one end of the rack 2 4;

[0022] Rack 1 3 and rack 2 4 are arranged on the supporting plate 1 for parallel sliding. The supporting plate 1 is provided with an electric cylinder 31 for driving rack 1 3. The supporting plate 1 is arranged on the machine tool body. Through the pre-set drilling and chamfering position, the three-dimensional coordinate position of the supporting plate 1 is controlled by the machine tool. The drilling and chamfering assembly and the measuring assembly can switchably contact with the automobile door sill beam 6.

[0023] A trapezoidal block 11 is arranged on the bearing plate 1, and the measuring assembly includes a rotating shaft 41 arranged at one end of the rack 4, a swing arm 42 rotatably arranged on the rotating shaft 41 at one end, and a probe module arranged at the other end of the swing arm 42, and a probe 43 for measuring the door sill beam 6 of the automobile is arranged on the probe module. A spring 44 is sleeved on the outer side of the rotating shaft 41, one end of the spring 44 is connected to the rotating shaft 41, and the other end of the rotating shaft 41 is connected to the swing arm 42, and the side of the swing arm 42 is detachably abutted against the trapezoidal block 11.

[0024] The drilling and chamfering assembly includes a motor 32 arranged at one end of a rack 3, and a drilling and chamfering integrated tool 33 connected to the output shaft of the motor 32. The axis of the probe 43 coincides with the axis of the drilling and chamfering integrated tool 33 through the swing of the swing arm 42.

[0025] Two guide grooves 12 are parallelly provided on the bearing plate 1 , and guide blocks 5 are respectively provided on the sides of the rack 1 3 and the rack 2 4 . The rack 1 3 and the rack 2 4 are slidably arranged in the guide grooves 12 through the guide blocks 5 .

[0026] The probe module is connected to a controller, and the controller is electrically connected to the electric cylinder 31, the motor 32 and the machine tool body respectively.

[0027] The specific working process of this utility model:

[0028] When in use, the load-bearing plate 1 is moved to a set position above the door sill beam 6 of the automobile clamped by the clamp by the machine tool, and the electric cylinder 31 is started. Figure 1 The electric cylinder 31 drives the rack 1 3 to slide upward along the guide groove 12, and the rack 1 3 drives the rack 2 4 to slide downward along the guide groove 12 through the gear 2. Under the action of the elastic force of the spring 44, the swing arm 42 connected to the rack 2 4 slides downward along the side of the bearing plate 1, and drives the probe 43 of the probe module downward to approach the car threshold beam 6. When the swing arm 42 slides until the probe 43 contacts the car threshold beam 6, the size of the car threshold beam 6 is measured;

[0029] After the probe 43 measures the size of the car door sill beam 6, the probe module transmits the data to the controller, and the controller controls the electric cylinder 31 to move in the opposite direction. The electric cylinder 31 drives the drilling and chamfering assembly to move downward through the rack 1 3, and drives the rack 2 4 to move upward through the gear 2. The rack 2 4 drives the probe module to move upward through the swing arm 42. When the swing arm 42 slides away from the carrier plate 1 and contacts the trapezoidal block 11, the swing arm 42 overcomes the elastic force of the spring 44 and starts to rotate along the rotating shaft 41.

[0030] The drilling and chamfering assembly continues to descend. Under the support of the trapezoidal block 11, the swing arm 42 drills the probe module to the side position of the drilling and chamfering assembly, which will not affect the descent of the drilling and chamfering integrated knife 33. The controller controls the electric cylinder 31 to extend until the rack 3 continues to descend so that the drilling and chamfering integrated knife 33 contacts the vehicle door sill beam 6, and drives the drilling and chamfering integrated knife 33 to drill through the motor 32. When the drilling and chamfering integrated knife 33 drills to a certain depth, chamfering can be performed. The controller controls the electric cylinder 31 is operated to realize the drilling and chamfering operations of the drilling and chamfering integrated tool 33, and the chamfering depth is controllable. After the processing of the automobile door sill beam 6 is completed, the electric cylinder 31 drives the rack 1 3 to rise, and drives the rack 2 4 to descend through the gear 2, and the swing arm 42 is gradually separated from the trapezoidal block 11. Under the action of the elastic force of the spring 44, the probe module is reset to the coaxial line between the probe 43 and the drilling and chamfering integrated tool 33, completing a drilling and chamfering operation, and finally the load-bearing plate 1 is driven to move through the machine tool to carry out the next drilling and chamfering process.

[0031] The carrying plate 1 is connected to the machine tool. The carrying plate 1 is provided with a drilling and chamfering assembly and a measuring assembly. The automobile sill beam 6 is measured by the probe 43 of the measuring assembly, and then the drilling and chamfering integrated cutter 33 of the drilling and chamfering assembly is used to perform drilling and chamfering. The carrying plate 1 is positioned by the machine tool, and the measurement, drilling and chamfering of the automobile sill beam 6 are completed at one time. The efficiency of the chamfering processing of the automobile sill beam 6 is relatively high.

[0032] The drilling and chamfering assembly is arranged on the rack 1 3, and the measuring assembly is arranged on the rack 2 4. The rack 1 3 and the rack 2 4 are respectively slidably arranged on the bearing plate 1 through the guide block 5. The rack 1 3 and the rack 2 4 are linked by the gear 2, so that the probe 43 of the measuring assembly and the drilling and chamfering integrated knife 33 of the drilling and chamfering assembly are alternately contacted with the automobile door sill beam 6, and the processing efficiency of the drilling and chamfering of the automobile door sill beam 6 is higher and the processing effect is better;

[0033] Through the cooperation between the swing arm 42 and the trapezoidal block 11 , the probe 43 and the integrated drilling and chamfering tool 33 are coaxially arranged, and the machining accuracy of the drilling and chamfering of the vehicle door sill beam 6 is higher.

[0034] Note: The probe, also known as the CNC probe, is a commonly used auxiliary device on CNC machine tools. It can quickly and accurately detect the position and shape of the workpiece and provide accurate reference coordinates for processing. The probe includes a probe rod and a probe ball. The probe rod is generally made of stainless steel or titanium, and the probe ball is generally made of ruby, silicon nitride, zirconium oxide and other materials. The probe is installed on the probe module through the probe system, where the probe module is a module for installing the probe and transmitting data to the controller. The probe technology is an existing technology and will not be described in detail here.
