Technical Field

[0001] This utility model relates to a self-grinding grinding head device for a horizontal machining table, belonging to the technical field of machine tool accessories. Background Technology

[0002] The rotary table is a core functional component of a machine tool. Developing its own rotary table is one of the technologies that Shenyang Machine Tool must master, but it is currently in the research and development stage. Directly manufacturing rotary table equipment is currently costly and carries technical risks, making it unsuitable for current production and operations.

[0003] Therefore, the company urgently needs to research a low-cost rotary table processing equipment that is adapted to the current production and operation environment, so as to provide a technical guarantee for the company's production and operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a self-grinding grinding head device for a horizontal machining table. The grinding head device is directly installed on the horizontal machining spindle and uses the existing horizontal machining spindle and the connected tool holder shaft as the output power to complete the precision requirements of the worktable grinding.

[0005] To solve the above problems, the specific technical solution of this utility model is as follows: A self-grinding grinding head device for a horizontal machining table, wherein a tool holder shaft and an output shaft are respectively provided in the grinding head box, and the tool holder shaft and the output shaft are arranged in parallel; one end of the tool holder shaft is matched with the horizontal machining spindle with a BT50 specification interface; the output shaft is supported in the grinding head box by a bearing assembly and a bushing, and one end of the output shaft extends out of the grinding head box and is connected to the grinding wheel; the two opposite ends of the tool holder shaft and the output shaft are connected by a transmission device to transmit the power of the horizontal machining spindle to the grinding wheel.

[0006] The transmission device includes pulleys and a belt. The two pulleys are connected to the corresponding shaft ends through expansion sleeves, and the two pulleys are connected to the belt together.

[0007] The grinding head box has a bent edge, which is connected to the fixing part of the horizontal machining center, and the other end is connected to the bushing by bolts.

[0008] The bearing assembly consists of several bearings arranged coaxially. The bearings are divided into two groups and are respectively set at both ends of the bushing. The two groups of bearings are positioned by a limiting sleeve.

[0009] The outer end of the output shaft is provided with a conical platform structure, and the conical platform is coaxially fitted with a connecting sleeve with a conical hole. The outer circumference of the connecting sleeve is provided with a grinding wheel.

[0010] The output shaft has a stud coaxially mounted on the outer end of its tapered structure; a boss is provided on one side of the grinding wheel via a connecting sleeve, and a limiting plate is provided on the other side; a nut is threaded onto the stud, and the end face of the nut is pressed against the limiting plate.

[0011] The self-grinding head device for the horizontal machining table surface of this application adopts the above-described structure and has the following advantages: 1. The existing horizontal machining center spindle power is used, and the transmission device is connected through the existing tool holder shaft to transmit the power to the parallel output shaft, which ultimately makes the grinding wheel rotate and completes the grinding of the worktable surface; 2. The self-grinding function of the worktable is achieved through the feed motion of the machine tool's own X, Y and B axes; 3. The transmission device adopts a pulley and belt transmission structure, which has an elastic buffering effect and can achieve smooth transmission; 4. In the current manufacturing of horizontal machining production lines, when a machine tool needs to be equipped with many worktables, the grinding head device of this application can be used to produce them in-house, thereby solving the problem of high cost of purchased worktables. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this application. Detailed Implementation

[0013] like Figure 1 As shown, a self-grinding head device for a horizontal machining table includes a tool holder shaft 3 and an output shaft 9 arranged parallel to each other within the grinding head housing 2. One end of the tool holder shaft 3 is fitted with a BT50 interface to the horizontal machining spindle 1, providing quick loading and unloading capabilities, strong clamping force, stable runout accuracy, and efficient and stable power output performance. The output shaft 9 is supported within the grinding head housing 2 by a bearing assembly 11 and a bushing 8, with one end extending out of the grinding head housing 2 and connected to the grinding wheel 10. The tool holder shaft 3 and the output shaft 9 are connected at opposite ends by a transmission device, transmitting the power of the horizontal machining spindle 1 to the grinding wheel 10.

[0014] To ensure smooth transmission, the aforementioned transmission device includes pulleys 4 and belt 5. The two pulleys 4 are connected to the corresponding shaft ends through expansion sleeves, and the two pulleys 4 are connected to belt 5 together.

[0015] The grinding head box 2 is provided with a bent edge, which is connected to the fixing component of the horizontal machining center to ensure the connection stability of the grinding head box 2. The other end of the grinding head box 2 is connected to the bushing 8 by bolts to axially position the bushing 8.

[0016] The bearing assembly 11 is composed of several bearings arranged coaxially. The bearings are divided into two groups and respectively set at both ends of the bushing 8. The two groups of bearings are positioned by a limiting sleeve, thereby realizing the radial positioning of the output shaft 9.

[0017] The outer end of the output shaft 9 is provided with a conical truss structure, and the conical truss is coaxially fitted with a connecting sleeve 7 having a conical hole. A grinding wheel 10 is provided on the outer circumference of the connecting sleeve 7. The conical truss structure enables automatic centering, saving time and effort in assembly.

[0018] A stud is coaxially mounted on the outer end of the tapered structure of the output shaft 9; a boss is provided on one side of the grinding wheel 10 via a connecting sleeve 7, and a limiting plate 13 is provided on the other side. A nut 14 is threaded onto the stud, and the end face of the nut 14 is pressed against the limiting plate 13. The limiting plate 13 and the connecting sleeve 7 together position the grinding wheel 10 in the axial direction.

[0019] During operation, the horizontal machining center spindle 1 is started to rotate, transmitting power to the belt conveyor via the tool holder shaft 3, and then to the output shaft 9, thereby rotating the grinding wheel 10. During the grinding process on the worktable, the self-grinding of the worktable surface can be achieved by controlling the feed of the horizontal machining center spindle 1 in each direction. After grinding is complete, the grinding head box 2 separates from the horizontal machining center spindle 1, and the tool holder shaft 3 also detaches from the horizontal machining center spindle 1 and is inserted into the next horizontal machining center spindle 1. This allows for the self-grinding of the worktable surface on another machine, significantly reducing outsourcing costs.
