Description

Technical Field

[0001] This utility model belongs to the technical field of drilling devices, specifically relating to a drilling device for an automobile seat frame. Background Technology

[0002] The car seat frame is the skeleton and basic structure of the seat. It is a structural assembly made of metal materials (steel, aluminum, magnesium alloy) through processes such as stamping, welding, and casting. The seat frame needs to be drilled during processing, usually by drilling equipment. The existing drilling equipment is the equipment used for drilling holes in the car seat frame.

[0003] Existing drilling devices for car seat frames involve clamping and fixing the seat frame, then lowering the drill bit to contact the seat frame surface and rotating it to drill. During drilling, the drill bit and mounting base rotate downwards. Furthermore, at the moment of penetration, the electric cylinder at the end of the adjustment mechanism cannot stop immediately and continues to move downwards a certain distance. This causes the lower surface of the clamping base to contact the seat frame surface during penetration, and the contact with the frame surface during rotation can easily cause friction damage to the seat frame, reducing drilling quality and affecting the convenience of friction protection during car seat frame drilling. Therefore, this utility model proposes a new car seat frame drilling device. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for automotive seat frames, in order to solve the problems mentioned in the background art, where the drill bit and the mounting seat rotate downwards during drilling, and at the moment of penetration of the seat frame, the electric cylinder installed at the end of the adjustment mechanism cannot stop immediately and will move downwards a certain distance, thereby causing the lower surface of the clamping seat to contact the surface of the seat frame during penetration, and the contact with the frame surface during rotation is prone to friction damage to the seat frame, thus reducing the drilling quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for an automotive seat frame, comprising a support base, a top frame fixed to the upper surface of the support base, an adjustment mechanism inside the top frame, an mounting base mounted on the lower surface of the adjustment mechanism via a main electric cylinder, a drilling bit mounted on the lower surface of the mounting base via a motor and a clamping seat, clamping elements mounted on both ends of the upper surface of the support base via auxiliary electric cylinders, an anti-scratch rolling mechanism located on the lower surface of the mounting base relative to the drilling bit, and a collecting mechanism located on the upper surface of the support base;

[0008] Preferably, a PLC controller is fixed to the bottom of the front surface of the support base, and the adjustment mechanism, the main electric cylinder and the auxiliary electric cylinder are all electrically connected to the PLC controller through wires.

[0009] Preferably, the anti-scratch rolling assembly includes a support turntable disposed on the outer surface of the drill bit, a fixing ring integrally disposed at the inner surface edge of the support turntable, the fixing ring being fixed to the surface of the drill bit by fixing bolts, and two balls rolling at the lower surface edge of the support turntable via a rolling groove.

[0010] Preferably, the stabilization component includes arc-shaped stabilizing plates disposed on both sides of the upper surface of the support turntable.

Locking bolts are threaded to the side of the mounting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing an anti-scratch rolling mechanism, the support turntable can be fixedly installed on the outer surface of the drill bit. When the drill bit rotates, the top ball rolls inside the rolling groove through the arc-shaped stabilizing plate. At the same time, the ball roll contacts the surface of the mounting base and stabilizes its rotation.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a car seat frame drilling device, including a support base 101, a top frame 102 fixed to the upper surface of the support base 101, an adjustment mechanism 103 inside the top frame 102, an installation seat 104 mounted on the lower surface of the adjustment mechanism 103 via a main electric cylinder, a drilling bit 107 mounted on the lower surface of the installation seat 104 via a motor and a clamping seat, and clamping parts 105 mounted on both ends of the upper surface of the support base 101 via auxiliary electric cylinders;

[0024] A PLC controller 106 is fixed to the bottom of the front surface of the support base 101. The adjustment mechanism 103, the main electric cylinder and the auxiliary electric cylinder are all electrically connected to the PLC controller 106 through wires.

[0025] The lower surface of the mounting base 104 is provided with an anti-scratch rolling mechanism on the surface of the drill bit 107. The anti-scratch rolling mechanism includes an anti-scratch rolling component at the top of the drill bit 107, stabilizing components on both sides of the upper surface of the anti-scratch rolling component, and a fixing mounting component at the bottom of the stabilizing component. When the clamping seat drives the drill bit 107 to rotate and drill through, the anti-scratch rolling mechanism contacts the surface of the seat frame for anti-friction rolling protection.

[0026] To prevent frictional damage to the clamping seat's contact with the skeleton surface during drilling, the anti-scratch rolling assembly is preferably provided in this embodiment. It includes a support turntable 1071 on the outer surface of the drill bit 107. A fixing ring 1072 is integrally provided at the inner edge of the support turntable 1071. The fixing ring 1072 is fixed to the surface of the drill bit 107 by fixing bolts. A second set of rolling balls 1078 rolls along the lower edge of the support turntable 1071 via a second rolling groove. After the support turntable 1071 is fixedly installed by the fixing ring 1072, the surface of the skeleton is protected from friction by the rolling contact between the support turntable 1071 and the second set of rolling balls 1078 when the drill bit 107 rotates to drill.

[0027] To facilitate stable control of the fixed ring 1072 after installation using a stabilization component, in this embodiment, preferably, the stabilization component includes arc-shaped stabilizing plates 1075 disposed on both sides of the upper surface of the support turntable 1071. Rolling grooves 1077 are equidistantly spaced at the top of the inner surface of the arc-shaped stabilizing plate 1075. Rolling balls 1076 roll inside the rolling grooves 1077. The surface of the rolling balls 1076 contacts the bottom surface of the mounting base 104. This allows for installation and control via the arc-shaped stabilizing plate 1075 after the support turntable 1071 is installed. Furthermore, when the arc-shaped stabilizing plate 1075 rotates, the rolling balls 1076 contact the surface of the mounting base 104, stabilizing and controlling the rotation adjustment.

[0028] To facilitate the fixed installation and control of the arc-shaped stabilizing plate 1075 using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes a mounting bolt 1074 disposed at the bottom end of the arc-shaped stabilizing plate 1075, and internal threaded holes 1073 matching the mounting bolt 1074 are provided on both sides of the upper surface of the support turntable 1071. After the bottom end of the arc-shaped stabilizing plate 1075 is closed on the surface of the support turntable 1071, the mounting bolt 1074 is rotated to embed into the internal threaded hole 1073 to fix the arc-shaped stabilizing plate 1075 in place.

[0029] The upper surface of the support base 101 is provided with a collection mechanism, which includes a material feeding and falling component provided on the upper surface of the support base 101 and a collection component provided at the top inside the support base 101. When residue falls through the holes on the surface of the support base 101, the collection mechanism can collect and process the residue, making collection convenient.

[0030] In order to facilitate the feeding and processing of fallen residue onto the surface of the support base 101 by means of the feeding and dropping component, in this embodiment, preferably, the feeding and dropping component includes a groove 1011 formed on the upper surface of the support base 101. Feeding inclined surfaces 1013 are formed on both sides of the inside of the groove 1011. A discharge channel 1012 is formed at the bottom end of the two feeding inclined surfaces 1013 at the middle position of the bottom end of the groove 1011. When the residue that has been punched falls into the groove 1011 on the surface of the support base 101, it is fed to the discharge channel 1012 through the internal feeding inclined surfaces 1013 and collected by the discharge channel 1012.

[0031] To facilitate the centralized collection and processing of residue after feeding, in this embodiment, preferably, the collection component includes mounting plates 1014 welded and fixed to both sides of the top inner part of the support base 101. A collection box 1015 is engaged and installed at the top inner part of the support base 101 via the mounting plates 1014. The discharge channel 1012 communicates with the interior of the collection box 1015. Locking bolts are threaded to the side of the mounting plates 1014. After the collection box 1015 is engaged and installed via the mounting plates 1014, the locking bolts are rotated to fix the installation. When residue falls into the discharge channel 1012, it can fall into the collection box 1015 for collection, facilitating centralized collection of residue.

[0032] The adjustment mechanism 103 in this utility model is prior art, disclosed in a car seat frame drilling device disclosed in authorized patent application number CN222001942U, and will not be described in detail here.

[0033] The working principle and usage process of this utility model are as follows: When using this car seat frame drilling device, the bottom end of the support base 101 is first placed stably on the ground at the usage position. Then, the seat frame is placed on the upper surface of the support base 101 and clamped by the clamping member 105. After clamping, the drilling path of the mechanism 103 is adjusted by programming through the PLC controller 106. The clamping base and the drilling drill bit 107 are rotated by the motor inside the bottom end of the mounting base 104. The main electric cylinder drives the mounting base 104 and the drilling drill bit 107 to move down to contact the seat frame for drilling.

[0034] Then, during drilling, the drill bit 107 penetrates the interior of the seat frame. At the moment of penetration, the second ball 1078 on the lower surface of the support turntable 1071 contacts the surface of the frame, making it less prone to friction damage when the second ball 1078 rolls against the surface of the frame. When the drill bit 107 rotates during drilling, it drives the arc-shaped stabilizing plate 1075 to rotate as well. When the arc-shaped stabilizing plate 1075 rotates, the top ball 1076 rolls inside the rolling groove 1077. At the same time, the first ball 1076 contacts the surface of the mounting base 104 to stabilize and control its rotation. Thus, at the moment of penetration, the support turntable 1071 and the second ball 1078 stabilize and control the surface of the frame while minimizing wear, improving the convenience of friction protection when drilling holes in the car seat frame.

[0035] Finally, when drilling, as the drill bit 107 passes through the frame, residue easily falls off the lower surface. At this time, the residue falling from the bottom of the frame onto the surface of the support base 101 enters the inside of the tank 1011. Inside the tank 1011, the material is guided down by the feeding ramp 1013 to the discharge channel 1012, and then falls again through the discharge channel 1012 to the inside of the collection box 1015 for collection. This facilitates the collection and processing of the residue that falls off during drilling, improves the convenience of the drilling device in collecting the residue that falls off the surface of the support base 101 when drilling the car seat frame, and ensures that the frame installation area does not exceed the area of ​​the tank 1011.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
