Description

Technical Field

[0001] The utility model relates to the field of processing equipment, in particular to a bench-type drilling machine for processing a brake caliper housing. Background Art

[0002] A brake caliper housing such as Figure 1 and Figure 2 As shown, it includes a shell body 8, on which a first column 81 is provided, one end of the first column 81 extends out of the shell body 8 and is provided with a connecting column 82, a hydraulic cavity 83 is provided on the end surface of the other end of the first column 81 along the axial direction of the column, and a mounting hole 84 is provided on the bottom wall of the hydraulic cavity 83, and a first assembly column 85 and a second assembly column 86 are fixedly connected to both ends of the shell body 8, a first assembly hole 87 is provided on the first assembly column 85, and a second assembly hole 88 is provided on the second assembly column 86, and the axis of the first assembly hole 87, the axis of the second assembly hole 88, the axis of the mounting hole 84, and the axis of the connecting column 82 are all parallel to each other.

[0003] The mounting hole 84 needs to be processed by drilling equipment, but in the actual processing process, the operator holds the shell body 8 and uses a drilling machine to drill the mounting hole 84. The handheld processing method cannot effectively limit and fix the shell body 8, which easily causes the shell body 8 to tilt during processing, making the processed mounting hole 84 not meet the requirements. Utility Model Content

[0004] The present application provides a bench-type drilling machine for machining a brake caliper housing, which positions the housing body by setting a limiting structure, thereby ensuring the machining quality of the mounting hole.

[0005] The present application provides a benchtop drilling machine for machining a brake caliper housing, which adopts the following technical solution:

[0006] A bench drilling machine for processing a brake caliper housing comprises a machine body, a processing platform arranged on the machine body, a column arranged on the processing platform, a spindle box arranged on the column, a drill bit and a handle arranged on the spindle box, a limit plate is provided on the processing platform, a socket for inserting a connecting column is opened on the limit plate, a limit block is provided on the limit plate, the limit block is located on one side of the socket, a first insertion rod for inserting into a first assembly hole is provided on the top of the limit block, when the connecting column is inserted into the socket and the first insertion rod is inserted into the first assembly hole, the processing area of ​​the mounting hole faces the drill bit.

[0007] By adopting the above technical solution, when it is necessary to process the mounting hole, the operator first holds the shell body and makes the cavity opening of the hydraulic cavity face upward, then inserts the connecting column into the socket and makes the bottom surface of the column contact with the top surface of the limit plate, and inserts the first plug rod into the first assembly hole, thereby completing the limit locking of the shell body, so that when the mounting hole is processed, the processing axis of the mounting hole can be parallel to the Z axis, thereby improving the processing accuracy of the mounting hole.

[0008] Preferably, the processing platform is also provided with an anti-deflection block for being inserted into the hydraulic cavity, and a limiting hole for the drill bit to pass through is opened on the anti-deflection block along the X-axis direction. The anti-deflection block is used to prevent the drill bit from deviating during movement.

[0009] By adopting the above technical solution, before processing the mounting hole, the anti-deviation block is first manually inserted into the hydraulic cavity, and the anti-deviation block is plugged into the hydraulic cavity. During drilling, the drill bit will pass through the limit block to perform the drilling operation. Because the diameter of the mounting hole is not large and the hydraulic cavity is relatively deep, the drill bit used to process the mounting hole is long and thin, which makes the end of the drill bit easily bent by force when drilling, so that the processed mounting hole cannot meet the requirements. Therefore, the anti-deviation block is set to prevent the end of the drill bit from bending when drilling, so that the processed mounting hole meets the requirements. The setting of the anti-deviation block also prevents the splash of processing debris, which improves the processing safety to a certain extent.

[0010] Preferably, the diameter of the anti-deflection block gradually increases from an end close to the limiting plate to an end away from the limiting plate, and the diameter of the end of the anti-deflection block away from the limiting plate is larger than the diameter of the hydraulic chamber.

[0011] By adopting the above technical solution, the anti-deviation block can be inserted into the hydraulic cavity more easily and accurately.

[0012] Preferably, a cylinder is provided on the machine body, the axis of the piston rod of the cylinder is parallel to the Z axis, a first connecting rod is provided on the piston rod of the cylinder, the anti-deflection block is provided on the end of the first connecting rod away from the cylinder, the anti-deflection block is located directly above the socket, when the connecting column is inserted into the socket and the first plug rod is inserted into the first assembly hole, the connecting column is located below the anti-deflection block, and the hydraulic chamber is located on the movement path of the anti-deflection block.

[0013] By adopting the above technical solution, after the shell body is pressed on the limit plate, the piston rod of the oil cylinder is retracted by controlling the oil cylinder, thereby driving the anti-deviation block to move downward and inserting the anti-deviation block into the hydraulic cavity. At the same time, the anti-deviation block presses the shell body on the limit plate, reducing the possibility of drill bit deviation during processing and ensuring the processing quality of the mounting hole.

[0014] Preferably, a placement groove is opened on the side wall of the body along the X-axis direction, the placement groove is located below the limiting plate, a collection frame is provided in the placement groove, and a first blanking groove connected to the placement groove is opened on the processing platform, and the bottom notch of the first blanking groove is located above the collection frame.

[0015] By adopting the above technical solution, after the mounting hole is processed, the processing debris in the hydraulic cavity can be directly poured into the first blanking chute, so that the processing debris falls into the collection frame, completing the collection of the processing debris.

[0016] Preferably, a pressing block is slidably connected to the machine body along the Z-axis direction, and a driving member for driving the pressing block to move along the Z-axis direction is also provided on the machine body. The pressing block is located on the side of the jack away from the limit block, and the pressing block is used to press the second assembly column.

[0017] By adopting the above technical solution, a pressing block is provided to press and limit the shell body, thereby further improving the stability of the shell body during processing, thereby ensuring the processing quality of the mounting hole.

[0018] Preferably, the driving member is a second connecting rod, one end of the second connecting rod is connected to the pressing block, and the other end of the second connecting rod is connected to the first connecting rod.

[0019] By adopting the above technical solution, the retraction of the piston rod of the oil cylinder will drive the first connecting rod to move downward, and when the first connecting rod moves downward, it will drive the second connecting rod to move downward, and when the second connecting rod moves downward, it will drive the pressing block to move downward, so that the pressing block presses the second assembly column. When the piston rod of the oil cylinder is extended, it will drive the first connecting rod to move upward, and when the first connecting rod moves downward, it will drive the second connecting rod to move, and when the second connecting rod moves downward, it will drive the pressing block to move, so as to release the pressing of the second assembly column by the pressing block.

[0020] Preferably, a second plug rod is provided at the bottom of the pressing block, and the second plug rod is plugged into the second assembly hole. The bottom of the second plug rod is conical, and the diameter of the bottom of the second plug rod gradually decreases from the side close to the top end of the second plug rod to the side away from the top end of the second plug rod. When the first plug rod is inserted into the first assembly hole, the second assembly hole is located on the movement path of the second plug rod.

[0021] By adopting the above technical solution, when the pressing block presses the second assembly column, it will also drive the second insertion rod to be inserted into the second assembly hole, thereby further limiting the position of the shell body.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model realizes the restricted positioning of the housing body by providing the insertion hole and the first insertion rod;

[0024] 2. The utility core is provided with an anti-deviation block to prevent the drill bit from deviating during movement;
